Ib tug serum muaj anti-A tshuaj tiv thaiv yog tov nrog ib co ntawm cov ntshav. Piv txwv li, yog tias ib tus neeg cov ntshav kuaj tau agglutinated los ntawm anti-A tshuaj tiv thaiv kab mob , tab sis tsis yog tiv thaiv -B tshuaj tiv thaiv , nws txhais tau hais tias A antigen tam sim no tab sis tsis yog B antigen. Yog li, hom ntshav yog A.
Ib yam li ntawd, koj tuaj yeem nug, anti A antibody txhais li cas?
A. Ib tiv thaiv - tshuaj tiv thaiv yog ib tshuaj tiv thaiv uas khi rau lwm tus tshuaj tiv thaiv ! Koj coj tus neeg mob lub hlwb liab thiab ntxiv me ntsis Coombs 'reagent (ib tshuaj tiv thaiv kab mob uas yuav khi rau qhov pib ntawm tib neeg immunoglobulin. Nws yog tsim los ntawm kev txhaj tshuaj tib neeg Ig rau lwm tus tsiaj, zoo li nas.).
Qhov thib ob, dab tsi yog anti A thiab anti B antibodies? Cov tshuaj tiv thaiv (agglutinins) rau antigens A thiab B muaj nyob rau hauv lub plasma thiab cov no yog term anti-A thiab anti - B . Qhov sib thooj antigen thiab tshuaj tiv thaiv yeej tsis pom nyob hauv tib tus neeg txij li thaum, thaum sib xyaw, lawv tsim antigen- tshuaj tiv thaiv complexes, zoo agglutinating cov ntshav.
Ib sab saum toj no, cov tshuaj tiv thaiv kab mob A ua dab tsi?
Cov tshuaj tiv thaiv ua tawm tsam ABO ntshav pawg antigens Anti -A thiab tiv thaiv -B khi rau RBCs thiab qhib qhov sib ntxiv cascade, uas lyses RBCs thaum lawv tseem nyob rau hauv txoj kev (intravascular hemolysis). Kev tuag feem ntau tshwm sim los ntawm kev hloov ntshav yog qhov tshwm sim ntawm kev hloov pauv ABO - ntshav tsis sib haum.
Hom ntshav twg muaj cov tshuaj tiv thaiv kab mob?
Cov ntshav B muaj B antigens nrog anti-A cov tshuaj tiv thaiv hauv cov ntshav. Cov ntshav pawg A muaj A antigens ntawm cov qe ntshav liab nrog cov tshuaj tiv thaiv. B cov tshuaj tiv thaiv kab mob hauv cov ntshav. Qhov sib xyaw ua ke ntawm antigens thiab tshuaj tiv thaiv kab mob txiav txim seb hom ntshav twg koj tuaj yeem tau txais kev nyab xeeb rau lub hom phiaj kho mob.

Sm RNP antibody kuaj ntshav yog dab tsi?
Extractable Nuclear Antigen Antibodies Yog li, cov panels uas kuaj rau cov ENAs tshwj xeeb tuaj yeem pab tau rau hauv kev ntsuam xyuas ntawm SARDs. Sm/RNP (U1 RNP) yog ENA txuam nrog MCTD. Anti-Sm / RNP cov tshuaj tiv thaiv yog cov cim ntawm MCTD thiab pom nyob rau hauv feem ntau ntawm cov neeg mob uas muaj tus kab mob
Puas yog Rh yog antigen lossis antibody?
Rh cov tshuaj tiv thaiv yog IgG cov tshuaj tiv thaiv uas tau los ntawm kev kis tau rau Rh-positive ntshav (feem ntau yog los ntawm cev xeeb tub lossis hloov ntshav cov khoom lag luam). D antigen yog qhov tiv thaiv kab mob tshaj plaws ntawm txhua qhov tsis-ABO antigens
