YUAV TSUM SIV

Diagnostic Kit for free Prostate Specific Antigen (fluorescence immunochromatographic assay) yog ib qho fluorescence immunochromatographic assay rau kom muaj nuj nqis nrhiav tau dawb Prostate Specific Antigen (fPSA) hauv tib neeg cov ntshav los yog ntshav. Qhov piv ntawm fPSA / tPSA tuaj yeem siv rau hauv kev kuaj mob sib txawv ntawm prostate cancer thiab benign prostatic hyperplasia. Tag nrho cov qauv zoo yuav tsum tau lees paub los ntawm lwm cov txheej txheem. Qhov kev sim no yog npaj rau kev siv kws kho mob nkaus xwb.
