Qhov sib txawv tseem ceeb ntawm PSA dawb thiab tag nrho PSA yog tias PSA dawb tsuas yog tus nqi ntawm cov dawb do ntab prostate-cov tshuaj tiv thaiv tshwj xeeb hauv cov hlab ntsha thaum tag nrho PSA yog tus nqi ntawm ob qho tib si ywj pheej ntab prostate-specific antigen hauv cov hlab ntsha thiab cov prostate-specific antigen khi rau lwm cov proteins.
Prostate-specific antigen (PSA), tseem hu ua gamma-seminoprotein lossis kallikrein-3, yog glycoprotein enzyme encoded los ntawm KLK3 noob. Epithelial hlwb ntawm prostate caj pas secrete prostate-specific antigens. PSA yog tsim rau ejaculation. PSA liquefies phev nyob rau hauv lub seminal coagulum thiab tso cai rau cov phev mus ua luam dej dawb do. Qhov no tso cai rau cov phev nkag mus rau hauv lub tsev menyuam. PSA tuaj yeem ntab hauv cov hlab ntsha. Daim ntawv no hu ua unbound los yog dawb PSA. Ntawm qhov tod tes, qhov khi PSA cuam tshuam nrog lwm cov proteins hauv lub cev. Qib PSA tag nrho yog hais txog tus nqi ntawm ob qho tib si khi thiab tsis muaj ntaub ntawv ntawm prostate-specific antigen.
PSA Dawb yog dab tsi?
PSA pub dawb yog tus nqi ntawm cov dawb do ntab prostate-specific antigen hauv cov hlab ntsha. Feem ntau PSA hauv cov ntshav yog khi rau cov ntshav cov protein. Tsuas yog ib qho me me xwb tsis yog khi rau cov ntshav cov protein. Qhov PSA no hu ua PSA dawb. Kev kuaj PSA pub dawb tuaj yeem ntsuas tus nqi PSA dawb hauv lub cev. Tsis tas li ntawd, qib PSA dawb yog qhov tseem ceeb heev los txiav txim siab qhov yuav ua rau mob qog noj ntshav hauv cov txiv neej. Feem ntau, cov qib PSA dawb feem ntau yog siab dua rau cov uas tsis yog mob qog noj ntshav ntawm prostate. Txawm li cas los xij, qib PSA dawb yog qis dua rau cov neeg mob qog nqaij hlav prostate.
Yog tias ib tus neeg muaj PSA tag nrho ntawm 4 txog 10 ng / mL, cov kws kho mob tuaj yeem kuaj cov ntshav kom dawb PSA qib. Ib qho piv txwv ntawm tus nqi ntawm PSA dawb rau tag nrho PSA siab dua 25% yog suav tias yog qhov qub.

PSA tag nrho yog dab tsi?
Tag Nrho PSA yog tus nqi ntawm ob qho tib si ywj pheej ntab prostate-specific antigen hauv cov hlab ntsha thiab cov prostate-specific antigen khi rau lwm cov proteins. Tag nrho PSA kuaj ntsuas ob qho tib si khi thiab tsis muaj ntaub ntawv ntawm PSA hauv lub cev los ntawm kev siv ntshav. Cov txiaj ntsig feem ntau tau tshaj tawm raws li nanograms ntawm PSA ib milliliter ntawm cov ntshav.
Cov kws kho mob yuav txiav txim siab tag nrho PSA qib ntawm 4 ng / mL thiab qis dua li qub. Yog li ntawd, yog tias ib tug neeg muaj PSA qib siab dua 4 ng / mL, cov kws kho mob feem ntau pom zoo kom kuaj xyuas cov qog nqaij hlav prostate los txiav txim seb puas muaj qog nqaij hlav hauv prostate. Txawm li cas los xij, tag nrho PSA yog qhov nyuaj thaum txiav txim siab mob qog noj ntshav. Qhov no yog vim cov kev tshawb fawb tsis ntev los no tau pom qee tus txiv neej uas muaj PSA tag nrho qis dua 4 ng / mL muaj mob qog noj ntshav prostate. Tsis tas li ntawd, qee cov neeg mob uas siv tshuaj xws li finasteride thiab dutasteride rau kev kho mob ntawm BPH tej zaum yuav muaj PSA qis dua vim muaj kev cuam tshuam ntawm cov tshuaj no.
Dab tsi zoo sib xws ntawm Dawb PSA thiab Tag Nrho PSA?

- Ob qho PSA dawb thiab tag nrho PSA yog qhov tseem ceeb rau cov txiv neej dua li poj niam.
- Lawv tuaj yeem ntsuas los ntawm kev ntsuas tshwj xeeb los ntawm kev siv ntshav.
- Ob leeg PSA dawb thiab tag nrho PSA raug yuam kom txiav txim siab PSA dawb rau tag nrho PSA piv.
- Tus nqi ntawm ob qho PSA dawb thiab tag nrho PSA yog qhov tseem ceeb los txiav txim siab txog kev pheej hmoo ntawm kev mob qog noj ntshav hauv cov txiv neej thiab xav tau tom ntej rau kev kuaj mob qog nqaij hlav prostate.
Qhov txawv ntawm PSA dawb thiab tag nrho PSA yog dab tsi?
PSA pub dawb tsuas yog tus nqi ywj pheej ntab prostate-cov antigen tshwj xeeb hauv cov hlab ntsha, thaum tag nrho PSA yog tus nqi ntawm ob qho tib si ywj pheej ntab prostate tshwj xeeb antigen hauv cov hlab ntsha thiab cov prostate-specific antigen khi rau lwm cov proteins. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm PSA dawb thiab tag nrho PSA. Tsis tas li ntawd, qib PSA dawb feem ntau yog siab dua rau cov neeg uas tsis muaj mob qog noj ntshav ntawm prostate.

Summary – Free PSA vs Total PSA
Prostate-specific antigen (PSA) yog glycoprotein enzyme uas tsim los ntawm cov qog prostate. PSA tuaj yeem txav mus rau hauv cov hlab ntsha dawb lossis tuaj yeem khi rau cov proteins hauv cov ntshav. Dawb PSA yog hais txog kev ywj pheej ntab prostate-specific antigen hauv cov hlab ntsha. Tag Nrho PSA yog hais txog tus nqi ntawm ob qho tib si ywj pheej ntab prostate-specific antigen hauv cov hlab ntsha thiab cov prostate-specific antigen khi rau lwm cov proteins. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm PSA dawb thiab tag nrho PSA.
