- The ferritin test measures the level of ferritin, the major iron storage protein in the body.
- The ferritin test is a simple blood test.
- High levels of ferritin can indicate an iron storage disorder, such as hemochromatosis, or a chronic disease process.
- Low levels of ferritin are indicative of iron deficiency, which causes anemia (a reduction in the number of red blood cells).
Brain natriuretic peptide (BNP) test measures the amount of the BNP hormone in your blood. BNP is made by your heart and shows how well your heart is working.
A hormone secreted by the adrenal glands that sit above the kidneys. Known as the "stress hormone," cortisol makes blood pressure and blood sugar levels rise. Chronic elevated blood pressure can increase an individual's risk for heart disease, high blood pressure, diabetes and obesity. Effectively managing stress may also help keep cortisol levels down and protect the immune system. Cortisol plays an important role in helping the body release insulin, maintain glucose levels and keep the immune system healthy.
TSH (Thyroid Stimulating Hormone)
Test is used to check for thyroid gland problems. TSH is produced when the hypothalamus releases a substance called thyrotropin-releasing hormone (TRH). TRH then triggers the pituitary gland to release TSH.
TSH causes the thyroid gland to make two hormones: triiodothyronine (T3) and thyroxine (T4). T3 and T4 help control your body's metabolism.
Triiodothyronine (T3) and thyroxine (T4) are needed for normal growth of the brain, especially during the first 3 years of life. A baby whose thyroid gland does not make enough thyroid hormone (congenital hypothyroidism) may, in severe cases, be mentally retarded. Older children also need thyroid hormones to grow and develop normally.
This test may be done at the same time as tests to measure T3 and T4.
