The CA 125 test is a simple blood test that measures a protein called cancer antigen 125. You may also hear CA-125 or cancer antigen 125 test. You can book at participating labs on LabFinder and we’ll guide you every step.
The CA-125 blood test, also called cancer antigen 125 or CA125, looks for the CA 125 protein in your blood. Levels can rise with some ovarian conditions and other causes of pelvic inflammation. This helps your doctor track changes over time.
Common reasons: your doctor is monitoring a known ovarian condition, checking treatment over time, investigating pelvic symptoms, or building a baseline for future comparison. If you are unsure, LabFinder’s physician oversight helps confirm the right test for you.
Check in at your chosen lab, share your ID and order, and roll up a sleeve. A small sample of blood is taken from your arm. Most visits take 15 to 30 minutes, and the draw itself is only a few minutes. The lab teams will work to keep you comfortable.
Yes, this is a quick, routine blood draw and is considered very safe. You might feel a quick pinch, notice a small bruise, or feel a little lightheaded for a moment afterward, but those effects usually fade quickly. Be sure to tell the staff if you take blood thinners, have a bleeding disorder, a rash or infection where blood will be drawn, or if you have fainted during blood draws before. They will take extra care to keep you comfortable. Your period, pregnancy, or a current pelvic infection can affect CA 125 levels, so mention these at check in.
Simple prep: fasting is not usually needed. Drink water so your veins are easy to find. Wear short sleeves or loose sleeves. Bring your photo ID and insurance card. Tell the team if you are on your period, pregnant, or recently had pelvic surgery. Follow any instructions from your doctor or the lab.
