Cancer Antigen 15-3 (CA 15-3) Test
Test Description:
The CA 15-3 test measures the level of cancer antigen 15-3 (CA 15-3) in the blood. CA 15-3 is a protein released by certain cancer cells, particularly breast cancer cells.
Indications of the Test:
This test is used to monitor certain types of cancer, especially breast cancer. It is often employed to track the progression of advanced-stage cancer and assess how it responds to treatment. However, it is not used to diagnose early-stage or localized breast cancer, as the levels of CA 15-3 are typically not elevated in such cases.
Patient Preparation/Instructions:
The test is a simple blood test that does not require any special preparation.
Typical Reference Values:
The typical reference range for CA 15-3 is less than 30 U/mL, but the specific range may vary depending on the laboratory and the test kit used.
Turn Around Time:
The turnaround time for the test is usually 2-3 days.
