Testsealabs PSA Prostate Specific Antigen Test
Inkcazelo emfutshane:
Uvavanyo lwe-PSA lweProstate Specific Antigen luvavanyo olukhawulezayo lwe-chromatographic immunoassay yokufumanisa umgangatho wePSA kwigazi elipheleleyo/serum/plasma.
 Iziphumo eziKhawulezayo: ILab-Chanekile kwiMizuzu | Ukuchaneka kweBanga leLebhu: ethembekileyo kwaye ethembekileyo |
| Vavanya naphi na: Akukho tyelelo lwaseLab olufunekayo | Umgangatho oqinisekisiweyo: 13485, CE, iMdsap iyahambelana |
| Ilula kwaye iSetyenzisiwe: Kulula ukuyisebenzisa, iZero Hassle | ULulelo olugqibeleleyo: Vavanya ngokukhululeka ekhaya |
I-Prostate Specific Antigen (PSA) yi-single-chain glycoprotein ene-molecular weight malunga ne-34 kDa. Ikho kwiindlela ezintathu eziphambili ezijikeleza kwiserum:
- I-PSA yasimahla
- I-PSA ibotshelelwe kwi-α1-antichymotrypsin (PSA-ACT)
- I-PSA ehlanganiswe ne-α2-macroglobulin (PSA-MG)
I-PSA ifunyenwe kwizicubu ezahlukahlukeneyo zenkqubo ye-urogenital yamadoda, kodwa ifihliwe kuphela yi-prostate glandular kunye neeseli ze-endothelial.
Kumadoda anempilo, inqanaba le-PSA le-serum liphakathi kwe-0.1 ng / mL kunye ne-4 ng / mL. Amanqanaba ePSA aphakamileyo angenzeka kuzo zombini iimeko ezinobungozi kunye nezibi:
- Iimeko ezinobungozi: umzekelo, umhlaza wedlala lobudoda
- Iimeko ezinobungozi: umzekelo, i-benign prostatic hyperplasia (BPH) kunye ne-prostatitis
Utoliko lwenqanaba lePSA:
- Inqanaba le-4 ukuya kwi-10 ng / mL lithathwa njenge "gray zone."
- Amanqanaba angaphezu kwe-10 ng / mL abonisa kakhulu umhlaza.
- Izigulana ezinexabiso le-PSA phakathi kwe-4–10 ng/mL kufuneka ziqhubeke nohlalutyo lwedlala lobudoda nge-biopsy.
Uvavanyo lwe-PSA sesona sixhobo sibaluleke kakhulu sokuxilonga umhlaza wedlala lobudoda kwangoko. Izifundo ezininzi ziqinisekisile ukuba i-PSA yeyona nto iluncedo kwaye inentsingiselo ye-tumor marker kumhlaza wedlala lesidoda, usulelo lwe-prostate, kunye ne-BPH.
Uvavanyo lwe-PSA lweProstate Specific Antigen lusebenzisa indibaniselwano ye-colloidal gold conjugate kunye ne-antibody ye-PSA ukuze ibone ngokukhethekayo iyonke i-PSA egazini, kwiserum, okanye kwiplasma. Ibe:
- Ixabiso lokunqunyulwa kwe-4 ng / mL
- Ixabiso lereferensi ye-10 ng / mL
