Testsealabs PSA Prostate Specific Antigen Test
Lus piav qhia luv luv:
PSA Prostate Specific Antigen Test yog qhov ntsuas chromatographic immunoassay sai rau kev kuaj pom zoo ntawm PSA hauv tag nrho cov ntshav / ntshav / ntshav.

Prostate Specific Antigen (PSA) yog ib txoj hlua glycoprotein uas muaj qhov hnyav ntawm kwv yees li 34 kDa. Nws muaj nyob rau hauv peb hom loj circulating nyob rau hauv cov ntshav:
- Dawb PSA
- PSA khi rau α1-antichymotrypsin (PSA-ACT)
- PSA complex nrog α2-macroglobulin (PSA-MG)
PSA tau raug kuaj pom nyob rau hauv ntau cov ntaub so ntswg ntawm tus txiv neej urogenital system, tab sis nws tsuas yog secreted los ntawm prostate glandular thiab endothelial hlwb.
Hauv cov txiv neej noj qab haus huv, cov ntshav ntshav PSA nyob nruab nrab ntawm 0.1 ng / mL thiab 4 ng / mL. Kev nce qib PSA tuaj yeem tshwm sim hauv ob qho tib si malignant thiab benign tej yam kev mob:
- Cov mob tsis zoo: xws li mob qog noj ntshav prostate
- Benign tej yam kev mob: piv txwv li, benign prostatic hyperplasia (BPH) thiab prostatitis
PSA theem txhais:
- Ib theem ntawm 4 txog 10 ng / mL yog suav tias yog "grey cheeb tsam."
- Qib siab tshaj 10 ng / mL yog qhov qhia tau tias mob qog noj ntshav.
- Cov neeg mob uas muaj PSA qhov tseem ceeb ntawm 4-10 ng / mL yuav tsum tau soj ntsuam ntxiv ntawm prostate ntawm biopsy.
Kev kuaj PSA yog cov cuab yeej tseem ceeb tshaj plaws rau kev kuaj mob qog noj ntshav thaum ntxov. Ntau cov kev tshawb fawb tau lees paub tias PSA yog qhov muaj txiaj ntsig zoo tshaj plaws thiab muaj txiaj ntsig zoo rau cov qog nqaij hlav cancer prostate, kab mob prostate, thiab BPH.
PSA Prostate Specific Antigen Test siv kev sib xyaw ua ke ntawm colloidal kub conjugate thiab PSA antibody los xaiv kuaj pom tag nrho PSA hauv cov ntshav, ntshav, lossis ntshav. Nws muaj:
- Tus nqi txiav tawm ntawm 4 ng / mL
- Kev siv tus nqi ntawm 10 ng / mL
