C-Reactive Protein (CRP) Test
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 .
Indicators
An antigen expressed by tissues derived from mullerian epithelium (tubal, endometrial and endocervical) or celomic epithelium (mesothelial cells of the pleura, pericardium and peritoneum). Although its biochemical nature has not been clearly defined, CA125 has been described as a glycosylated, high-molecular-weight protein that may be released from damaged cells. Measurable in plasma, CA125 is a sensitive, nonspecific tumor marker for ovarian cancer; as such it is much more useful for monitoring clinical responses to the treatment of ovarian cancer than for the diagnosis of ovarian cancer. Elevated plasma CA125 may occur in association with other malignancies and non-malignant gynecologic disorders. (NCI04)
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.
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
Hemoglobin where the heme group has formed a stable complex with carbon monoxide (CO). This complex is produced after CO has been inhaled or as a byproduct of hemoglobin, protoporphyrin or dichloromethane catabolism. The heme-CO complex is approximately 200 times more stable than heme-oxygen complexes. Thus, high levels of carboxyhemoglobin in the circulation can lead to tissue hypoxia and death.
Tests
Blood proteins released when heart muscle is injured; the primary laboratory marker in the evaluation of possible acute myocardial infarction.
Glossary Term
Enzymatic (e.g. dUTP/UNG) and physical measures that stop amplified DNA from contaminating later runs. Labs with high daily volumes usually require dUTP/UNG chemistry in purchased assays; confirm this when comparing kits from different manufacturers.
Tests
The determination of cellular CD64 expression in a biological specimen.
Tests
A ceruloplasmin test measures the amount of ceruloplasmin in a sample of your blood. Your liver makes ceruloplasmin by attaching copper to a protein. Your liver releases the ceruloplasmin into your bloodstream so it can carry copper to the parts of your body that need it.
