Also found in: Dictionary.

complexed prostate-specific antigen

(kŏm-plekst′, kom′plekst″),

cPSA

A laboratory test that assays levels of prostate-specific antigen bound to alpha-1-chymotrypsin. The cPSA test is slightly more useful in the detection of prostate cancer than the simple PSA test but may not be as accurate as assessments of serum unbound or free PSA.
