Cancer Antigen 15-3

This Cancer Antigen (CA) 15-3 Blood Test measures antigens released into the blood by certain types of cancer cells. Breast cancer most commonly releases CA 15-3 into the blood, often after cancer treatment has been initiated.

Antigens such as CA 15-3 are often called tumor markers. However, a CA 15-3 blood test is not used as a screening tool or diagnostic test to identify cancer. The CA 15-3 test is used used with other clinical evaluations to monitor cancer treatment. Test results may take 1-3 business days after you order online and visit lab
