Prostata-spetsiifiline antigeen on eesnäärme toodetud valk, mida mõõdetakse vereprooviga eesnäärmehaiguste, sealhulgas vähiriski hindamiseks, sõeluuringuks ja jälgimiseks, aidates sõeltestida eesnäärmevähki, jälgida ravitulemusi ja uurida kuseteede vaevusi.
PSA kontsentratsiooni normiks vere bioloogilisel analüüsil peetakse väärtust kuni 4,0 ng/mL, kuid see sõltub vanusest, noorematel meestel on norm madalam, nt alla 2,5 ng/mL.
Prostate-specific antigen is a protein produced by the prostate gland that is measured via a blood test to assess, screen for, and monitor prostate diseases - including the risk of cancer - thereby aiding in prostate cancer screening, the monitoring of treatment outcomes, and the investigation of urinary tract disorders.
Traditionally, a PSA value of up to 4,0 ng/mL is considered the norm, but this depends on age; for younger men, the norm is lower, for example, below 2,5 ng/mL.
