IKORESHWA RYITEGANYANYE

Ikizamini cyo gusuzuma indwara ku buntu Ikizamini cya Prostate Specific Antigen (ikizamini cya fluorescence immunochromatographic assay) ni ikizamini cya fluorescence immunochromatographic assay cyo gupima ingano ya Prostate Specific Antigen (fPSA) mu maraso y'umuntu cyangwa mu maraso. Igipimo cya fPSA/tPSA gishobora gukoreshwa mu gusuzuma kanseri ya prostate na hyperplasia ya prostate idakabije. Ikizamini cyose cyagaragaye kigomba kwemezwa n'ubundi buryo. Iki kizamini kigenewe gukoreshwa n'abaganga gusa.

INSHAMAKE

Antigen ya prostate yihariye (fPSA) ni antigen ya prostate yihariye irekurwa mu maraso mu buryo bw'ubwisanzure igasohoka n'uturemangingo twa prostate epithelial. PSA (Prostate Specific Antigen) ikorwa kandi igasohoka n'uturemangingo twa prostate epithelial mu masohoro kandi ni kimwe mu bice by'ingenzi bigize plasma y'imisemburo. Irimo ibisigazwa 237 bya aside amine kandi uburemere bwayo bungana na 34kD. Ifite imikorere ya serine protease ya glycoprotein imwe, igira uruhare mu gikorwa cyo gushonga kw'amasohoro. PSA mu maraso ni igiteranyo cya PSA yigenga na PSA ihujwe. Igipimo cya plasma y'amaraso, muri 4 ng/mL ku gaciro k'ingenzi, PSA muri kanseri ya prostate Ⅰ ~ Ⅳ igihe cy'ubuhanga bwa 63%, 71%, 81% na 88% hakurikijwe uko bikurikirana.
