Nutrition
Tests that determine whether you’re receiving proper nutrition can help identify underlying causes of chronic symptoms and provide important information during major physical events, such as pregnancy.
This test measures B12 and folate—two vitamins that cannot be produced in the body and must be supplied by the diet. They are required for normal red blood cell (RBC) formation, repair of tissues and cells, and the synthesis of DNA. B12 is essential for proper nerve function.
Test description: In addition to health reasons, B12 and folate tests may be used to help evaluate an individual with an altered mental state or other behavioral changes, especially in the elderly. A B12 test may be ordered with folate, by itself, or with other screening laboratory tests such as a complete blood count (CBC), comprehensive metabolic panel (CMP), antinuclear antibody (ANA), C-reactive protein (CRP), and rheumatoid factor (RF) to help determine why a person shows signs and symptoms of a condition affecting nerves (neuropathy).
This test is recommended for: Pregnancy ante-natal work-up, diagnosing and monitoring treatment of anemia, suspected folate/B12 deficiency, strict vegetarians.

This profile is designed to evaluate your current nutrition status or to evaluate certain anemias.
Test description: This test evaluates your current nutrition status and includes:
-
- Vitamin B12
- Folate
- Hemoglobin
- Lipid Profile
- A1c Hemoglobin
Both vitamin B12 and folic acid are vitamins that help the body make red blood cells. Hemoglobin is a component of the CBC used to check for anemia. A lipid panel is completed to determine the risk of developing heart disease due to cholesterol build up in the arteries. Patients who are at risk may include those who are overweight, physically inactive, diabetics, and those who eat diets high in fat. The A1c Hemoglobin is used to screen and monitor diabetes.
Patients must fast for 12 hours prior to the test.

This test is used to asses a patient’s vitamin D status, and rule out vitamin D deficiency as a cause of bone disease.
Test description: When calcium is low and/or a person has symptoms of vitamin D deficiency, such as bone malformation in children (rickets) and bone weakness, softness, or fracture in adults (osteomalacia), 25-hydroxyvitamin D usually is ordered to identify a possible deficiency in vitamin D.
The test may be requested when an individual is known to be at risk of vitamin D deficiency or to monitor levels of those taking supplements. Older adults, people who are institutionalized or homebound and/or have limited sun exposure, those who are obese, who have undergone gastric bypass surgery, and/or who have fat malabsorption are at an increased risk of a vitamin D deficiency. Also included in this group are people with darker skin and breastfed infants.
The determination of 25-OH vitamin D in serum or plasma is used in the assessment of vitamin D sufficiency. Since 25-OH vitamin D is the predominant circulating form of vitamin D in the normal population, it is considered to be the most reliable index of vitamin D status. The measurement of 25-OH vitamin D is becoming increasingly important in the management of patients with various disorders of calcium metabolism associated with rickets, neonatal hypocalcemia, pregnancy, nutritional and renal osteodystrophy, hypoparathyroidism, and postmenopausal osteoporosis.
This test can reveal problems related to bone metabolism or parathyroid function, possible Vitamin D deficiency, or malabsorption.
