Thyroid Panel with TSH - This panel provides an assessment of thyroid function and includes tests for thyroid stimulating hormone (TSH), total thyroxine (T4), triiodothyronine (T3) uptake (T3 resin uptake), and free T4 index. This panel may be useful for evaluating thyroid function when pituitary disease is not suspected. The results of the panel may help in the diagnosis of hyperthyroidism and hypothyroidism. T3 and T4 are hormones derived from the thyroid and released into the blood to regulate metabolism. Both T3 and T4 are produced in response to TSH from the pituitary gland. T4 circulates mostly bound to plasma proteins, with a small amount unbound and available for biological activity. To estimate free T4 concentration, a total T4 test and T3 uptake test are used to calculate the free T4 index. A normal TSH result excludes most cases of primary overt thyroid disease. Therefore, a cascaded testing approach (test code 15102) may be preferable for evaluating and monitoring thyroid f

Vitamin B12 (Cobalamin) and Folate Panel, Serum - Folic acid deficiency is common in pregnant women, alcoholics, patients with diets that do not include raw fruits and vegetables, and people with structural damage to the small intestine. The most reliable and direct method of diagnosing folate deficiency is the determination of folate levels in both erythrocytes and serum. Low folic acid levels, however, can also be the result of a primary Vitamin B12 deficiency that decreases the ability of cells to take up folic acid. B12 is decreased in pernicious anemia, total or partial gastrectomy, malabsorption and certain congenital biochemical disorders.

As a naturopathic physician, former Chief Scientific Officer of a nutraceutical company, and member of MADE SAFE’s Scientific Advisory Board, I bring a discerning eye to clean beauty and high-quality supplements. I look beyond the label, to ingredients, formulation, and the science behind them. My recommendations consider when and how to use supplements, potential interactions with medications, and how everything fits into your care.
