Radioimmunoassay (RIA) refers to a biochemical test that uses radioactive isotopes (radioisotopes) to measure the presence and quantity of antigens in a given sample. At the Asian Hospital and Medical Center’s Nuclear Medicine Services unit, we offer a series of RIA laboratory tests to assess thyroid function and measure hormone levels for accurate diagnosis of a variety of diseases.
We offer our patients a full range of RIA laboratory tests, as follows:
- TSH (thyroid-stimulating hormone) – This is a blood test that measures the level of hormones that the thyroid gland produces. It is typically done to check for hormonal imbalances and thyroid disorders such as hyperthyroidism and hypothyroidism.
- T4 (thyroxine) – This blood test is used to measure the amount of thyroxine (T4) hormones in the body and diagnose thyroid diseases.
- T3 (triiodothyronine) – This blood test is used to measure the amount of triiodothyronine (T3) hormones in the body and diagnose thyroid diseases.
- FT4 (free thyroxine) – This blood test measures the amount of T4 that is not bound by protein.
- FT3 (free triiodothyronine) – This blood test measures the amount of T3 that is not bound by protein.
- Combination of 3 (TSH, FT4 and FT3) – These three tests are used to assess the function of the thyroid and detect hormonal issues and thyroid diseases.
- Thyroid Profile (TSH, T4, T3) – These three tests are used to measure the hormone levels of the body, assess thyroid function and diagnoses thyroid diseases.
- Anti-TPO (anti-thyroid peroxidase) – This test is used to detect autoimmune diseases affecting the thyroid gland and its functions.
- Anti-Thyroglobulin – This test detects the presence of an antibody called anti-thyroglobulin, which disrupts the production of the thyroglobulin protein that is responsible for producing thyroid hormones.
- Thyroglobulin – This is a protein produced by the thyroid gland that allows it to produce the hormones that the body needs to sustain its many metabolic processes. This test measures the amount of thyroglobulin and the body and can also be used to detect thyroid tumors.
- Thyroid receptor (TRAb) – This is a diagnostic test used to diagnose an autoimmune disorder called Graves’ disease that causes an overactive thyroid (hyperthyroidism).
- Cortisol – This test measures levels of cortisol, a steroid hormone that regulates metabolism and immune response.
- PTH (Intact PTH) – This test is used to measure calcium levels and diagnose parathyroid disorders.
- ACTH (adrenocorticotropic hormone) – This test is used to measure the level of adrenocorticotropic hormone, which regulates cortisol production.
- Aldosterone – This test measures levels of aldosterone, which regulates blood pressure by controlling salt and potassium levels in the body.
- Renin – This test measures levels of renin, an enzyme produced by the kidney to help regulate blood pressure.
- Prolactin – This test is used to measure levels of prolactin, a hormone produced by the pituitary gland that stimulates milk production and lactation after childbirth.
- LH (luteinizing hormone) – This test measures LH, which regulates the function of the ovary and testes
- FSH (follicle-stimulating hormone) – This test is used to assess the levels of FSH, which triggers ovulation in women and sperm production in men.
- DHEAS (dehydroepiandrosterone) – This test measures DHEAS, which contributes to the production of estrogen in women and testosterone in men.
- Estradiol – This test measures levels of estradiol, which is a form of estrogen produced by the ovaries.
- PSA (prostate-specific antigen) – This test measures levels of PSA protein in both normal and cancer cells, and is used to diagnose prostate problems such as an enlarged prostate gland, prostatitis or prostate cancer.
- Testosterone – This test measures levels of testosterone, which is the male sex hormone that controls sex drive and sperm production.
- Beta human chorionic gonadotropin (HCG) – This test can be used to detect the HCG hormone and confirm or monitor pregnancy.
- 17-OH Progesterone (17-hydroxyprogesterone – This test is used to check for congenital adrenal disorders.
- Insulin assay – This test is used to diagnose hyperglycemia and pancreatic tumors.
- Parathyroid hormone-related protein (PTHrP) – This test is primarily used to diagnose hypercalcemia.
