Cancer Antigen 125 Serum Cost Comparison

86304 (CPT)

A Cancer Antigen 125 (CA-125) serum test is a simple blood test that measures the level of a protein called CA-125 in your bloodstream. Your doctor might order this test to help monitor certain cancers, particularly ovarian cancer, or to track how well cancer treatment is working. During the test, a healthcare provider will draw a small sample of blood from your arm, similar to a routine blood draw, and the sample will be sent to a laboratory for analysis.
