UKUSETYENZISWA OKUJOLISWEYO
Ikhithi yokuxilongakwiProstate Specific Antigen (uvavanyo lwe-fluorescence immunochromatographic) yi-fluorescence immunochromatographic
uvavanyo lokufumanisa ubungakanani be-Prostate Specific Antigen (PSA) kwi-serum okanye kwi-plasma yomntu, esetyenziswa kakhulu ekuxilongeni isifo se-prostate. Zonke iisampulu ezilungileyo kufuneka ziqinisekiswe zezinye iindlela. Olu vavanyo lwenzelwe
ukusetyenziswa kweengcali zempilo kuphela.
ISISHWANKATHELO
I-PSA（Prostate Specific Antigen） yenziwe kwaye ikhutshwe ziiseli ze-prostate epithelial kwiiseli zesidoda kwaye yenye yezona zinto ziphambili kwi-plasma yesidoda. Iqulethe ii-amino acid residues ezingama-237 kwaye ubunzima bayo be-molecular bumalunga ne-34kD. Inomsebenzi we-serine protease we-single chain glycoprotein, ithatha inxaxheba kwinkqubo yolwelo lwesidoda. I-PSA egazini yi-PSA edibeneyo kunye ne-PSA edibeneyo. Amanqanaba e-plasma yegazi, kwi-4 ng/mL yexabiso elibalulekileyo, i-PSA kumhlaza we-prostate Ⅰ ~ Ⅳ ixesha lobuthathaka be-63%, 71%, 81% kunye ne-88% ngokulandelanayo.
