Thyroglobulin Blood Test

Measures thyroid hormones to assess metabolic regulation and thyroid gland function.

Protein blood tests measure the levels of specific proteins in your blood, most commonly albumin and globulin. Albumin is the most abundant protein in your blood, produced by the liver, and plays a crucial role in maintaining fluid balance and transporting hormones, vitamins, and medications. Low albumin can indicate liver disease, kidney disease, malnutrition, or chronic inflammation. Globulins include antibodies (immunoglobulins) that fight infection, transport proteins, and clotting factors. The albumin-to-globulin (A/G) ratio provides additional diagnostic information about liver and immune system function.
