Tests
This test measures the amount of a protein called CA-125 (cancer antigen 125) in a sample of your blood. CA-125 is a type of tumor marker. Tumor markers are substances that are often made by cancer cells or by normal cells in response to cancer.

Indicators
Calcitonin (32 aa, ~3 kDa) is encoded by the human CALCA gene. This protein is involved in the modulation of blood calcium and phosphate concentrations through promoting incorporation of these ions into bone.
Indicators
A heterodimeric or heterotetrameric protein complex comprised of protein S100A8 and protein S100A9. This complex is expressed in the cytosol of neutrophils and macrophages and plays a role in multiple host defense related processes including immunomodulation, neutrophil chemotaxis and both antibacterial and antifungal responses.
Tests
A calprotectin stool test measures a protein called calprotectin in a sample of your stool (poop). The test is also called a fecal calprotectin test. It's used to check for inflammation (swelling and irritation) in your intestines.

Indicators
This gene plays a role in calcium binding and protein folding.
Article
Research record from Diagnostics (Basel), 2026-03-27. PMID 41975718.
Indicators
A tricyclic compound chemically related to tricyclic antidepressants (TCA) with anticonvulsant and analgesic properties. Carbamazepine exerts its anticonvulsant activity by reducing polysynaptic responses and blocking post-tetanic potentiation. Its analgesic activity is not understood; however, carbamazepine is commonly used to treat pain associated with trigeminal neuralgia.
Tests
A carbon dioxide (CO2) blood test measures the amount of carbon dioxide in your blood. Carbon dioxide is an odorless, colorless gas. It is a waste product from metabolism, the process your body uses to make energy from food you eat.

Indicators
A cancer-specific antigen associated with both tumors and the developing fetus. The main use of this antigen is as a tumor marker, especially with respect to intestinal cancers. Production of the antigen ceases shortly before birth, but may reappear in people who develop certain types of cancer.
Indicators
Proteins released into blood when heart muscle is injured; the central laboratory marker in suspected heart attack.
Tests
Blood proteins released when heart muscle is injured; the primary laboratory marker in the evaluation of possible acute myocardial infarction.

Indicators
This gene is involved in G-protein-coupled receptor signaling and calcium homeostasis.
