Hemoglobin A1c (HcbA1c) – Quest Diagnostics

Only $24

DLS Regular Price: $34

Fasting Required:

Specimen: Blood

Results: 1-2 Business Days

Description: This non-fasting test, also known as A1c, HbA1c, or Glycated hemoglobin, indicates how well you have controlled your diabetes over the last few months. Even though you may have some very high or very low blood glucose values, Hemoglobin A1C will give you a picture of the average amount of glucose in your blood over that time period. While the Hemoglobin A1C is the standard tool to determine blood sugar control for patients with diabetes, it is not a substitute for daily, routine blood glucose testing.

Fasting Required:
Yes, 10-12 Hours

Specimen: Blood

Results: 3-5 Business days

Tests Included:

Lipids: This is a group of simple blood tests that reveal important information about the types, amount and distribution of the various types of fats (lipids) in the bloodstream. Includes Total Cholesterol, HDL (good) Cholesterol, LDL (bad) Cholesterol, Risk Ratio (good to total), and Triglycerides.

Complete Blood Count (CBC's): It is a blood test that checks hemoglobin, hematocrit, red blood cells (RBC), white blood cells (WBC), and platelets. Used as a broad screening test to check for such disorders as anemia, infection, and many other diseases. Changing levels of red or white blood cells can indicate disease or infection and are very helpful in a health screening.

Fluids and Electrolytes: Electrolytes are minerals in your body that have an electric charge. They are in your blood, urine and body fluids. Maintaining the right balance of electrolytes helps your body's blood chemistry, muscle action and other processes. Sodium, potassium, chlorine, and carbon dioxide are all electrolytes. You get them from the foods you eat and the fluids you drink. Levels of electrolytes in your body can become too low or too high. That can happen when the amount of water in your body changes, causing dehydration or overhydration. Causes include some medicines, vomiting, diarrhea, sweating or kidney problems. Problems most often occur with levels of sodium, potassium or calcium. It includes: Chloride, Potassium, Sodium and Carbon Dioxide.

TSH: The thyroid-stimulating hormone (TSH) is produced in the pituitary gland and stimulates the production of thyroid hormones. The TSH helps identify an underactive or overactive thyroid state.

Liver: The liver panel includes several blood tests measuring specific proteins and liver enzymes in the blood. This combination of blood tests is designed to give you a complete picture of the state of your liver and help detect liver disease and measure potential liver damage. Some of the blood tests are associated with the integrity of the liver cells (i.e. ALT), some with liver function (i.e. albumin) and some with disease linked to the biliary system (i.e. alkaline phosphatase). Includes: Albumin, Alkaline Phosphatase, Alanine Transaminase (ALT or SGPT), Aspartate Transaminase (AST or SGOT), Total Bilirubin, Total Protein, LDH, Total Globulin, Albumin/Globulin Ration and GGT.

Kidney: This basic metabolic panel is a group of blood tests that provides information about your body's metabolism. This test is done to evaluate kidney function, blood acid/base balance, blood sugar levels. It includes Blood Urea Nitrogen (BUN), Creatinine, BUN/Creatinine Ratio, eGFR, and Uric Acid.

Glucose Changes in blood glucose are a good indicator of metabolic function and can help detect diseases like diabetes mellitus. Since diabetes is the most common cause of kidney disease in adults, it is important to monitor for this disorder when evaluating kidney function.

Mineral and Bone: In addition to its mechanical functions, the bone is a reservoir for minerals (a "metabolic" function). The bone stores 99% of the body's calcium and 85% of the phosphorus. It is very important to keep the blood level of calcium within a narrow range. If blood calcium gets too high or too low, the muscles and nerves will not function. In times of need, for example, during pregnancy, calcium can be removed from the bones. It includes: Total Iron, Calcium, and Phosphorus.

Vitamin D, 25-Hydroxy: This highly automated test measures both D2 and D3 together and reports a total 25-hydroxy.

Vitamin D is also known as the "sunshine vitamin" because the body manufactures the vitamin after being exposed to sunshine. Ten to 15 minutes of sunshine 3 times weekly is enough to produce the body's requirement of vitamin D. Needed for strong bones and teeth, Vitamin D helps your body absorb the amount of calcium it needs. It also has other roles in the body, including modulation of cell growth, neuromuscular and immune function, and reduction of inflammation. 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.

Vitamins Panel – Quest Diagnostics

Only $269

DLS Regular Price: $346

Fasting Required:
Yes, 10-12 Hours

Specimen: Blood

Results: 7-10 Business days after receiving specimen

Special Instructions: Refrain from vitamins, alcohol and fruits 24 hours prior to sample collection. Dietary supplements containing biotin may interfere in assays and may skew results to be either falsely high or falsely low. For patients receiving the recommended daily doses of biotin, draw samples at least 8 hours following the last biotin supplementation. For patients on mega-doses of biotin supplements, draw samples at least 72 hours following the last biotin supplementation. No foods containing vitamin A should be ingested in the previous 48 hours before blood draw.

Tests Included:

Vitamin A: Also known as retinoids, Vitamin A ensures good eyesight and healthy skin. It also helps to strengthen the immune system.

Vitamin B1: Vitamin B1 (thiamine) acts as a coenzyme in the metabolism of the body. Deficiency of thiamine leads to the disease beriberi, a disease affecting the heart and nervous system.

Vitamin B6: A cofactor for enzymes. Deficiency in this leads to inflammation of the skin and mouth, nausea, vomiting, dizziness, weakness and anemia.

Vitamin B9(Folic Acid): Aids in the diagnosis of central nervous system disorders and anemia. This important nutrient also plays a significant role in making red blood cells, making DNA, energy level, muscle strength and memory.

Vitamin B12: The main function of vitamin B12 is forming red blood cells and sustaining the nervous system. Deficiency of Vitamin B12, disturbs the DNA causing abnormalities. The abnormalities show through excessive tiredness, breathlessness and a defective immune system.

Vitamin C: Aids in several metabolic reactions and is therefore extremely important for digestion. It is an important antioxidant as well. Along with that, it helps in the formation of collagen which is a principal protein that structures the bones, muscles, cartilages and blood vessels. It aids in the maintenance of teeth, bones and capillaries and advances the absorption of iron. It also helps in maintaining healthy body tissues and a strong immune system. Having a high content of vitamin C leads to healthy gums. It improves vision and is extremely effective in healing wounds and burns. It also reduces the effects of sun exposure and decreases the blood sugar of people suffering from diabetes.

Vitamin D, 25 Hydroxy: Used in the absorption of calcium and phosphorus in the body. As it promotes calcium absorption, it aids in proper growth and development of bones. Vitamin D also helps in strengthening teeth and bones. Secondly, one of the most important benefits of vitamin D is that it enhances the immune system of the body which consequently helps in reducing the risk of several diseases and infections.

Vitamin E: Splendid antioxidant properties. Vitamin E plays a protective and restorative part in several body functions. It protects the body cells from oxidative damage and improves overall health of a person.

Vitamin K: Vitamin K is produced by bacteria present in our large intestine. It is required for clotting of blood and also for bone formation.

Hemoglobin A1c – Ayumetrix Kit

Only $45

DLS Regular Price: $69

Note: This is a home specimen collection kit that will be mailed to you.

Fasting Required:

Specimen: Breath

Results: 5-7 Business days after receiving specimen

Special Instructions: Sample should be collected within the first 30 minutes of waking in the morning.

Description: Hemoglobin A1C is a form of hemoglobin (a blood pigment that carries oxygen) that is bound to glucose. Blood HbA1c levels are reflective of how well diabetes is controlled. The normal range for level for hemoglobin A1c is less than 6%. HbA1c levels are reflective of blood glucose levels over the past six to eight weeks and do not reflect daily ups and downs of blood glucose. High HbA1c levels indicate poorer control of diabetes than levels in the normal range.

Vitamin D – Ayumetrix Kit

Only $64

DLS Regular Price: $89

Note: This is a home specimen collection kit that will be mailed to you.

Fasting Required:

Specimen: Blood Spot

Results: 5-7 Business days after receiving specimen

Special Instructions: Sample should be collected within the first 30 minutes of waking in the morning.

Description: Vitamin D is a fat-soluble vitamin critical to calcium absorption which helps in bone growth, density, and strength. Without sufficient vitamin D, bones can become brittle or misshapen. Varying levels of vitamin D in the blood are associated with common variants in the following genes: (1) GC (transports vitamin D to organs), (2) NADSYN1/DHCR7 (needed for bioavailability of the vitamin D precursor molecule), and (3) CYP2R1 (helps convert inactive vitamin D to its active form). Maintaining adequate levels of Vitamin D has been shown to benefit patients in the maintenance of bone health for osteoporosis treatment, and in the prevention of fractures.
