Tests
This test measures the level of C-peptide in a sample of your blood or urine (pee). C-peptide is a chain of amino acids (the building blocks of proteins) that your pancreas makes in the process of making insulin. Insulin is a hormone that your pancreas makes to help blood glucose (blood sugar) get into your cells, where it can be used for energy. This helps keep your blood glucose at healthy levels.
Tests
A c-reactive protein test measures the level of c-reactive protein (CRP) in a sample of your blood. Your liver makes CRP in response to inflammation.
Tests
A CA 19-9 test measures the amount of a protein called CA 19-9 (cancer antigen 19-9) in a sample of your blood. CA 19-9 is a type of tumor marker. Tumor markers are substances made by cancer cells or by normal cells in response to cancer .
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
CA 19-9 is a fucosylated glycosphingolipid carbohydrate antigen that is soluble and is adsorbed to erythrocytes and to many adenocarcinomas of the digestive tract, especially pancreatic tumors. By structure CA 19-9 is related to the Lewis blood group antigens.
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.
Tests
A calcitonin test uses a sample of your blood to measure your levels of calcitonin, a hormone made in your thyroid gland by cells called “C cells.” Your thyroid is a small, butterfly-shaped gland in your neck, and C cells grow on the inside part of your thyroid (the medulla).
Tests
A calcium blood test measures the amount of calcium in your blood. Too much or too little calcium in your blood may be a sign of a wide range of medical conditions, such as bone disease , thyroid diseas e, parathyroid disorders , kidney disease , and other conditions.

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
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.
