TE WHAKAMAHINGA I WHAKATAURANGIA
Kete Tātaritangamō te Prostate Specific Antigen (fluorescence immunochromatographic assay) he whakamātautau fluorescence immunochromatographic
whakamātautau mō te kitenga tauanga o te Prostate Specific Antigen (PSA) i roto i te toto tangata, i te plasma rānei, e whakamahia ana hei āwhina i te tautuhi i te mate prostate. Me whakaū katoa ngā tauira pai mā ētahi atu tikanga. Ko tēneiwhakamātautaumō
mō te whakamahinga a ngā tohunga hauora anake.
WHAKARĀPOPOTONGA
Ka hangaia te PSA (Prostate Specific Antigen) e ngā pūtau epithelial prostate ki roto i te purapura, ā, ko tētahi o ngā wāhanga matua o te plasma purapura. Kei roto e 237 ngā toenga waikawa amino, ā, ko tōna taumaha ngota he tata ki te 34kD. He mahi serine protease tōna e rite ana ki te glycoprotein mekameka kotahi, e whai wāhi ana ki te tukanga waimeha purapura. Ko te PSA i roto i te toto ko te tapeke o tā rātou PSA me te PSA whakakotahi. Ko ngā taumata plasma toto, i roto i te 4 ng/mL mō te uara matua, ko te PSA i roto i te mate pukupuku prostate Ⅰ ~ Ⅳ wā o te tairongo o te 63%, 71%, 81% me te 88% ia.
