  • Alkaline Phosphatase

    This blood test measures Alkaline Phosphatase levels. Alkaline phosphatase is a group of enzymes found throughout the body, specifically in the bone, liver, placenta and intestine. Like all enzymes, it is needed in small amounts to trigger specific chemical reactions. Differing forms of the enzyme occur in healthy and malignant tissues. Alkaline Phosphatase is dependent on zinc for optimal functioning. Low levels of alkaline phosphatase are associated with zinc deficiency. Common causes of elevated alkaline phosphatase include extra-hepatic or common bile duct obstruction, viral hepatitis, colitis, ulcers and fatty liver disease. Another cause of an elevated alkaline phosphatase may be due to the presence of organisms (bacteria, yeast and amoebas) and their toxins that are easily absorbed into an already compromised digestive barrier, which may precipitate an auto-immune response. Lowered levels may indicate anemia, hypothyroidism and osteoporosis.

  • Coenzyme Q10 (CoQ10)

    Coenzyme Q10 is also known as Ubiquinone. This blood test is used to measure blood levels of CoQ10. CoQ10 is critical for the basic functioning in all cells and specifically to cardiac tissue due to the high-energy demands of cardiac cells. CoQ10's primary role is to protect and nurture mitochondria the principal energy source of the cell. CoQ10 molecules play a critical role in supporting the transport of electrons between enzymes that produce energy within cells. Research has shown that CoQ10 is an extremely powerful antioxidant and helps support the nervous system. Medical studies have shown there is a relationship between low levels of CoQ10 and disease processes such as Parkinson's disease, diabetes, gum disease, hypertension, cancer and muscular dystrophy. Factors related to CoQ10 deficiency include poor diet, thyroid dysfunction, the aging process and antidepressants. Statins sold in Canada carry a warning label on them stating that CoQ10 depletion may lead to impaired cardiac function in patients with known heart failure.

  • Folate (Folic Acid) Vitamin B9

    This blood test measures folate levels within blood. Folate is categorized as a B vitamin. Folate is needed for the synthesis of DNA in rapidly dividing cells. Symptoms associated with folate deficiency may include mental confusion, forgetfulness, cognitive decline, depression, irritability, diarrhea, macrocytic anemia with weakness or shortness of breath, peripheral neuropathy, sore or swollen tongue, peptic or mouth ulcers, headaches and heart palpitations. Low levels of folate can also lead to elevated levels of homocysteine. DNA synthesis and repair may be impaired and this could lead to the development of a potential cancer. Folic acid levels may be elevated when Vitamin B 12 is low, since Vitamin B 12 is needed in order for folate to enter the cells.

  • Glucose-6-Phosphate Dehydrogenase (G6PD) Quant Blood and RBC

    This blood test is used to detect a Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency. G6PD is found in all human cells but plays a significant role in red blood cells. Glucose-6-Phosphate Dehydrogenase is an enzyme that uses metabolic reactions to support the cell's ability to keep glutathione in its reduced form and support the metabolic roles that support vitamin C and E's antioxidant functions. G6PD deficiency is a sex-linked trait and is the most prevalent enzyme deficiency in the world. Approximately 400 million people live with this enzyme deficiency. It is most prevalent in people of Mediterranean, African and Asian descent. Glucose-6-Phosphate Dehydrogenase deficiency is also known as favism and primaquine sensitivity. Other substances that should be used with caution in those affected with G6PD deficiency are antimalarials and sulfonamide antibiotics. Questions have been raised about the safety of vitamin C use in G6PD deficient persons. The iron level in G6PD deficient cells may interact with the Vitamin C causing red blood cells to rupture promoting a hemolytic crisis. To prevent complications, administration of Vitamin C in those affected by a G6PD deficiency should be closely observed.

  • Magnesium RBC (Red Blood Cell)

    RBC Magnesium is the most precise blood test measuring intracellular magnesium levels. Magnesium is a critical mineral to overall health and well-being. It is estimated that over one half of all Americans may be deficient in magnesium. Studies have shown that those with cardiovascular disease and diabetes have depleted levels of magnesium and postmenopausal women are severely depleted. Magnesium plays many vital roles in preventing heart disease, controlling blood pressure and maintaining healthy cholesterol levels. Magnesium is needed for over 300 enzymatic reactions in the body, including the intracellular production of energy, and muscle contraction and relaxation. Magnesium deficiency contributes to a wide range of imbalances such as muscle cramps and spasms, tremors, neuromuscular disorders and may cause cardiac arrhythmias that result in sudden cardiac death.

  • Reverse Triiodothyronine (rT3)

    This blood test measures levels of Reverse T3 (rT3). A Reverse Triiodothyronine (rT3) is a thyroid hormone that disrupts the activity of the active the form of thyroid hormone, triiodothyronine (T3). When thyroid hormone is functioning properly, thyroxine (T4) is converted to the active hormone (T3). When reverse T3 is elevated, metabolic rhythms orchestrated by the active thyroid hormone (T3) act as if they were hit by a stun gun. Elevated levels of reverse T3 is also known as thyroid resistance because it mimics many of the same symptoms seen in those who suffer with low thyroid function (hypothyroidism). Some of those symptoms are fatigue, weight gain, cold hands, dry skin, hair loss, moodiness and a decline in cognitive function. Research has cited multiple factors that can generate an elevation in reverse T3. Some of those causes are: physical stress/trauma, strict dieting, chemical exposure, liver and kidney disease, severe illness, heavy metal toxicity, certain medications such as Propranolol (beta blockers), elevated cortisol, low iron levels, and lack of certain cofactors such as selenium and zinc which are crucial for healthy thyroid function.

  • Selenium (24 Hour Urine)

    This 24-hour urine test measures selenium levels. Selenium is an essential trace element. It is widely recognized as a key nutrient in cancer prevention and is a crucial cofactor for the conversion of T4 to T3 in healthy thyroid function. Selenium protects genes from inflammatory disease processes such as dementia, stroke, heart disease, diabetes and asthma. Selenium plays a crucial role by helping the body detoxify naturally from heavy metals such as cadmium. Cigarettes are a significant source of cadmium exposure worldwide. Cadmium has been found in toxic levels in fertilizers, pesticides and PVC plastics. Cadmium toxicity affects the lungs, brain, kidneys and bones and may lead to problems such as fatigue, confusion, depression and cardiac arrhythmias.

    Test Preparation For Optimal Results:

    A 24-hour urine collection must be submitted for this test to be completed. The specimen container for the 24-hour urine collection can be picked up at any Quest Diagnostics lab collection site. The Quest Diagnostics staff will be happy to answer any questions or concerns. Instructions for a 24-hour urine are as follows:


    1. The specimen collection starts by discarding the first urine passed upon rising. It is important to empty the
    bladder completely.

    2. Except for the discarded urine passed upon the morning rise, place ALL of the urine passed during the next 24 hours in the specimen container obtained at the Quest Diagnostics collection site. Urine passed during bowel movements must be included in the collection process.

    3. Maintain the specimen container at room temperature.

    4. Avoid contact with metal during the collection process.

    5. At the same time the following morning, empty the bladder completely one more time and add this sample to
    the collection container. This completes the collection process.

  • Vitamin A

    This test is used to evaluate the amount of Vitamin A in the blood.

    Test Description:
    We have twice as many Vitamin A receptors than Vitamin D receptors. Vitamin A is needed for growth and for strong teeth and bones, as well as for healthy skin and for eye health. Sources of Vitamin A are liver, dairy products, fish liver oils, dark green and yellow-orange vegetables and in some fruits.

    Detailed Information:
    Vitamin A is an oil- soluble vitamin also known as retinol. Beta Carotene is not actually a vitamin. It is a precursor of Vitamin A. Vitamin A has specific maintenance roles in our body and carotenoids such as beta carotene are stored in reserves and are easily converted into Vitamin A. Research shows that beta carotenes also act as antioxidants. Vitamin A supports vision, skin growth and repair, bone growth as well as protection from diseases such as cancer, macular degeneration, atherosclerosis and Alzheimer’s Disease. Deficiencies can be caused by lack of Vitamin A in the diet, malabsorption problems such as diarrhea or fat malabsorption & problems with recurrent infections. Insufficient levels of vitamin A are a major nutritional problem throughout the world to include the United States. Vitamin A is present in liver, fish liver oils, dairy products, dark green and yellow-orange vegetables, and in fruits. Beta-carotenes are antioxidants that protect cells against oxidative damage that predisposes cellular balances that may lead to inflammatory processes such as caner. Carotenoids, including beta-carotene are very low in people with Alzheimer’s disease. Carotenoids are found in dark colored fruits and vegetables.

    Test Preparation for Optimal Results:
    For optimal results, please fast a minimum of eight hours. No foods containing vitamin A should be eaten 48 hours prior to the lab test.

  • Vitamin B1 (Thiamine)

    This blood test measures Vitamin B1 (Thiamine) levels. Vitamin B1 (Thiamine) was the first B Vitamin discovered. All of the water-soluble B vitamins work as a team to help promote healthy nerves, skin, eyes, hair, liver, muscle tone and cardiovascular function. Vitamin B1 is a water-soluble vitamin and acts as a coenzyme and is essential for a number of reactions in metabolism. Vitamin B1 is involved in many body functions including the nervous system, muscle function, metabolism and digestion. Because Vitamin B1 is water soluble and very little is stored in the body, depletion of this vitamin can occur rapidly. Vitamin B1 metabolism is extremely complex and is the focus of continuing research. Vitamin B1 is an essential nutrient as it plays a vital role in carbohydrate, protein and lipid metabolism. Thiamine deficiency can develop after only one month of a thiamine-free diet. Mild thiamine deficiency occurs in pregnant women (due to their increased requirement), diabetics, the elderly and in malabsorption syndromes. Severe thiamine deficiency is a disorder called beriberi.

    Test Preparation For Optimal Results:

    If possible, have the lab collected early in the morning or shortly after waking. Do not take supplements on the day of the test. For comparison purposes, have subsequent labs collected close to the same time.

  • Vitamin B12

    This blood test measures Vitamin B12 levels. All of the water-soluble B vitamins work as a team to help promote healthy nerves, skin, eyes, hair, liver, muscle tone and cardiovascular function. Vitamin B12 is necessary for red blood cell production and neural function. Deficiencies in Vitamin B12 may be due to an inherited factor, limited dietary intake or problems with absorption (due to lack of intrinsic factor or gastric secretions in the stomach). A Vitamin B12 deficiency can cause anemia, neurologic disorders and an elevation in the inflammatory marker homocysteine, which has been implicated in Alzheimer's disease. If B12 is deficient, the body can have a difficult time using the B vitamin, folate.

    Test Preparation For Optimal Results:
    If possible, have the lab collected early in the morning or shortly after waking. For comparison purposes, have subsequent labs collected close to the same time.

  • Vitamin B12 & Folate

    This blood test measures both Vitamin B12 and Folate levels. All of the water-soluble B vitamins work as a team to help promote healthy nerves, skin, eyes, hair, liver, muscle tone and cardiovascular function. Adequate levels help to protect from the mental strain caused by depression and anxiety. Vitamin B12 helps spark the production of healthy red blood cells and is needed to support the nervous system. Vitamin B12 helps support the synthesis of the neurotransmitter, serotonin. Conditions associated with decreased levels of Vitamin B12 include anemia, nervous system disorders, memory, muscle strength, hypochlorhydria (low levels of needed stomach acid) and inflammatory bowel diseases. A Vitamin B12 deficiency can cause neuropathy in a treatable dementia, which is most often seen after the age of forty. Folic Acid is the co-enzyme required for purine synthesis and blood production. A deficiency of folic acid can cause symptoms similar to those seen in a deficiency of Vitamin B12, which is why it is recommended both of these B vitamins be checked at the same time. Current research has shown that B vitamins may help reduce levels of homocysteine, an inflammatory marker strongly associated with Alzheimer's disease.

All of the water-soluble B vitamins work as a team to help promote healthy nerves, skin, eyes, hair, liver, muscle tone and cardiovascular function. Vitamin B6 is needed to make red blood cells and maintain a healthy immune and nervous system. Vitamin B6 appears to offer significant protection against the development of diabetic nerve disease (neuropathy). Research has shown that individuals with long-standing diabetes, or those developing signs of peripheral nerve abnormalities, may benefit from Vitamin B6 supplementation. Elevated homocysteine levels due to a B6 deficiency may damage arterial walls, which can cause cholesterol to build up and block the vessels. A decreased level of Vitamin B6 impairs immune function by inhibiting the production of interleukin 2 and lymphocyte proliferation. Vitamin B6 deficiency may be related to heart disease, stroke, neurologic conditions, carpal tunnel syndrome, and even PMS.

    Preparation For Optimal Results:
    If possible, have the lab collected early in the morning or shortly after waking. Do not take supplements on the day of the test. For comparison purposes, have subsequent labs collected close to the same time.

  • Vitamin D 25-Hydroxy

    This blood test measures Vitamin D 25 (OH) levels. Vitamin D, known as the "sunshine vitamin." Vitamin D is a fat-soluble prohormone that the body can synthesize as Vitamin D3 (cholecalciferol) when the skin is exposed to ultraviolet-B (UBV) rays from the sun. Vitamin D is needed for strong bones and teeth, Vitamin D helps your body absorb the amount of calcium and phosphorus it needs. It also has other roles in the body, including modulation of cell growth, neuromuscular and immune function, and reduction of inflammation. Though controversial at times, research demonstrating the importance of Vitamin D3 continues to accumulate, while illuminating the threats that low levels pose to overall health and well-being. There are associations between low Vitamin D levels and peripheral vascular disease, certain cancers, multiple sclerosis, rheumatoid arthritis, juvenile diabetes, Parkinson's, and Alzheimer's disease.In May of 2009, an article published by William B. Grant, PhD of the Sunlight, Nutrition, and Health Research Center (SUNARC) demonstrated that a strong correlation exists between Alzheimer's and Vitamin D deficiency. In 2010, it was reported at the Alzheimer's Association International conference in Hawaii that older men and women with low levels of Vitamin D were approximately four times as likely to suffer from memory deficits. There are two primary ways that people lose teeth - dental caries and periodontal disease. Both conditions are linked to low Vitamin D levels. Low serum Vitamin D levels have been associated with a rise in the incidence of cardiovascular diseases, diabetes mellitus, depression, dental caries, cancer, osteoporosis, and periodontal disease, all of which are either considered risk factors for dementia and cognitive decline. Low Vitamin D levels also plays a role in hypertension, chronic pain, muscle weakness, muscle wasting, pre-term births as well as birth defects and autoimmune diseases and the list is mounting. In 2008, a number of studies reported that those with higher Vitamin D serum levels had greatly reduced risk of incidence or death from cardiovascular diseases. Research has shown that Vitamin D is neuroprotective and plays a vital role in reducing inflammation and plays an integral role in brain development and function. Vitamin D may also remove toxins from brain tissue. Some researchers are declaring Vitamin D deficiency as "pandemic". Research has shown that 41% of outpatients in the United States between the ages of 49-83 had low circulating Vitamin D levels. In the first year of being institutionalized, almost all elderly people are at risk for becoming Vitamin D deficient. Vitamin D is critical for everyone's optimal health.

  • Vitamin D, 1,25-Dihydroxy

    Vitamin D, 1,25-Dihydroxy Vitamin D. Also known as: 1,25-Dihydroxycholecalciferol, Vitamin D, 1,25-Dihydroxy. This test is frequently used to measure Vitamin D levels in the blood.

    Test Description:
    This test may be used when evaluating a Vitamin D deficiency or to evaluate parathyroid function or bone metabolism.

    Detailed Information:
    Vitamin D is certainly an important topic and news about Vitamin D can be found all over social media, health journals and commercials. The only way to know your vitamin D status is to test for it. There are two major metabolites of vitamin D: Vitamin D 25 OH and Vitamin 1, 25 - Dihydroxy. Vitamin D 1,25-Dihydroxy is the most potent of the various vitamin D metabolites. Its action stimulates calcium absorption in the intestine and its production is tightly regulated through concentrations of serum calcium, phosphorus, and parathyroid hormone.

    Vitamin D is rapidly metabolized in the liver to form 25-hydroxy (OH) vitamin D. Additional hydroxylation of 25-OH vitamin D takes place in the kidney by 1-alpha hydroxylase, under the control of parathyroid hormone, to yield 1,25-dihydroxy vitamin D. Vitamin D 1,25-Dihydroxy levels are frequently decreased in hypoparathyroidism and in chronic renal failure.

    Test Preparation for Optimal Results:
    No fasting required.

  • Vitamin K1

    This blood test measures Vitamin K1 levels. Vitamin K1 is also known as phylloquinone or phytomenadione. Vitamin K1 is necessary for the production of circulating coagulation factors. A deficiency in Vitamin K may result in excessive bleeding. Vitamin K1 deficiency maybe induced by malabsorption conditions such as Celiac Disease, pancreatitis, diarrhea and antibiotic use. According to a study published in 2008 in The American Journal of Epidemiology, an increase in vitamin K1 intake may reduce the prevalence of chronic inflammation that has been linked to numerous disease processes. Chronic inflammation occurs when the body's natural protective mechanisms overreact. Research has demonstrated that chronic inflammation is associated with numerous health threats including Alzheimer's disease, cardiovascular disease, arthritis and diabetes.

    Test Preparation For Optimal Results:
    If possible, have the lab collected early in the morning or shortly after waking. For comparison purposes, have subsequent labs collected close to the same time.

  • Zinc

    This blood test measures Zinc levels. Zinc is a crucial trace element required for the growth and healthy development of all living organisms. Zinc deficiency can lead to immune system dysfunction and impairments in growth, cognitive dysfunction, poor carbohydrate metabolism and hormonal function. Low dietary zinc is associated with hypogonadism, low Insulin Growth Factor-1, low testosterone and low levels of the thyroid hormone Free T4. It is estimated that nutritional zinc deficiency affects over 2 billion people worldwide, especially those in developing countries. The USDA's 1996 Continuing Survey of Food Intake has documented that over 70% of Americans do not consume the recommended daily allowance for zinc. Zinc is second to iron in body content and is found largely in the intracellular components of tissues in the liver, pancreas, kidney, bone, muscles, eyes, prostate, fingernails and skin. It is a cofactor for more than 300 known enzymes and plays a crucial role in maintaining the healthy function of DNA, RNA and transcription factors. Zinc is necessary to maintain normal serum testosterone. Inadequate zinc levels prevent the pituitary gland from releasing luteinizing and follicle stimulating hormones, which stimulate testosterone production. Zinc deficiency may have an impact on the male prostate gland. Research is ongoing to assess a possible correlation between zinc levels and prostate health. Zinc competes with copper and may contribute to a copper imbalance.

    Test Preparation For Optimal Results:
    If possible, it is best to have these labs drawn early in the morning (shortly after waking) and to have subsequent labs drawn for comparison purposes drawn at this same time.
