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 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
A second generation radioimmunoassay to measure serum levels of CA-125.
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
An element with atomic symbol Ca, atomic number 20, and atomic weight 40.08.
Tests
A calcium in urine test measures the amount of calcium in your urine (pee). If your urine calcium levels aren't normal, it may be a sign of kidney disease , a parathyroid disorder , bone diseas e, or another condition that affects how your body uses calcium.
Tests
The determination of the amount of cancer antigen 19-9 present in a sample.
