UKUSETSHENZISWA OKUHLOSIWE

Ikhithi Yokuxilonga yamahhala I-Prostate Specific Antigen (i-fluorescence immunochromatographic assay) iyi-fluorescence immunochromatographic assay yokuthola inani le-Prostate Specific Antigen (fPSA) yamahhala ku-serum noma ku-plasma yomuntu. Isilinganiso se-fPSA/tPSA singasetshenziswa ekuxilongweni okuhlukile komdlavuza we-prostate kanye ne-benign prostatic hyperplasia. Wonke amasampula abonisa ukuthi akhona kumele aqinisekiswe ngezinye izindlela. Lokhu kuhlolwa kuhloselwe ukusetshenziswa kochwepheshe bezempilo kuphela.

ISIFINYEZO

I-antigen ye-prostate-specific (fPSA) yamahhala iyi-antigen ye-prostate-specific ekhishwa egazini ngendlela ekhululekile futhi ikhishwa ngamaseli e-epithelial ye-prostate. I-PSA（Prostate Specific Antigen） ikhiqizwa futhi ikhishwe ngamaseli e-epithelial ye-prostate ibe yi-semen futhi ingenye yezingxenye eziyinhloko ze-plasma yesimila. Iqukethe ama-amino acid residues angu-237 futhi isisindo sayo sama-molecule singama-34kD. Inomsebenzi we-serine protease we-single chain glycoprotein, ihlanganyela enkambisweni yoketshezi lwesimila. I-PSA egazini iyisamba se-PSA yamahhala kanye ne-PSA ehlanganisiwe. amazinga e-plasma yegazi, ku-4 ng/mL ngenani elibalulekile, i-PSA kumdlavuza we-prostate Ⅰ ~ Ⅳ isikhathi sokuzwela okungu-63%, 71%, 81% kanye no-88% ngokulandelana.
