CA 15.3 is generally used for monitoring, not as a standalone screening test.
Ca 15.3 is a laboratory blood test. It is commonly used as a breast cancer marker. The test used mainly for monitoring selected breast cancer cases.
Doctors may also include it in treatment response assessments. The result should be read with the laboratory range, symptoms, medical history and other relevant results. The listed sample type is Blood (Serum).
A routine blood draw is low risk. You may feel a brief sting when the needle goes in, and some people notice temporary bruising, soreness or light-headedness afterwards. Fainting and infection are uncommon. The sample is collected at your home by a trained phlebotomist using sterile equipment, and the draw takes only a few minutes. If you feel unwell during or after collection, tell the phlebotomist or speak to your doctor.
