Tests
A thyroglobulin test measures the amount of a protein called thyroglobulin (Tg) in a sample of your blood. Your thyroid (a small, butterfly-shaped gland in your neck) makes thyroglobulin along with many other important hormones . Together, these hormones control bodily activities such as your heart rate and how fast you burn calories from food.
Indicators
Thyroglobulin (2768 aa, ~305 kDa) is encoded by the human TG gene. This protein is involved in thyroid hormone synthesis.
Tests
A thyroid antibody test measures the level of thyroid antibodies in a sample of your blood to check for an autoimmune thyroid disease . Your thyroid is a small, butterfly-shaped gland in your neck. It makes hormones that control many activities in your body, including your heart rate and how fast you burn calories from food.
Tests
Thyroxine is also called T4. T4 is a hormone that your thyroid gland makes. A T4 test measures the level of T4 in a sample of your blood. Too much or too little T4 may be a sign of a thyroid problem .

Indicators
Tissue-type plasminogen activator (562 aa, ~63 kDa) is encoded by the human PLAT gene. This protein plays a role in the cleavage of plasminogen between Arg-580 and Val-581 to form the fibrinolytic enzyme plasmin.
Indicators
This gene may play a role in the regulation of apoptosis.
Tests
The determination of the total amount of human interferon gamma present in a serum sample.
Tests
A total protein and albumin/globulin (A/G) ratio test measures the total amount of protein in your blood. Proteins have many important functions, including giving your body energy, rebuilding muscles, and helping your immune system . Your body might make too much or too little protein if you have certain health conditions.

Tests
A TP53 genetic test uses a sample of your blood, bone marrow, or tissue from a tumor to look for changes in the tumor protein 53 gene, or TP53 for short. Changes in your genes are also called gene variants or mutations.
