Qhov kev kuaj ncaj qha antiglobulin (DAT) yog siv feem ntau rau pab txiav txim seb qhov ua rau hemolytic anemia yog vim cov tshuaj tiv thaiv txuas nrog RBCs. Hemolytic anemia yog ib qho mob uas cov qe ntshav liab (RBCs) raug rhuav tshem sai dua li lawv tuaj yeem hloov pauv.
ATYA zoo txhais li cas?
Cov txiaj ntsig kev xeem kuj tseem tuaj yeem txawv txav yam tsis muaj laj thawj meej, tshwj xeeb tshaj yog cov neeg laus. Qhov txawv txav (zoo) tsis ncaj ncees Coombs kuaj txhais tau tias koj muaj cov tshuaj tiv thaiv uas yuav tawm tsam cov qe ntshav liab uas koj lub cev pom zoo li txawv teb chaws.
Lub hauv paus ntsiab lus ntawm kev kuaj Antiglobulin yog dab tsi?
PRINCIPLE: Kev kuaj ncaj qha antiglobulin (DAT) yog siv los ua kom pom qhov muaj lossis tsis muaj IgG thiab C3 ntawm cov ntshav liab. Cov qe ntshav liab uas muaj IgG thiab/lossis C3 absorbed rau lawv qhov chaw raug xa mus rau cov qe ntshav liab sensitized.
Dab tsi yog qhov tseem ceeb ntawm kev sim Coombs tsis ncaj?
Qhov kev kuaj tsis ncaj rau Coombs feem ntau ua tiav kom pom cov tshuaj tiv thaiv hauv tus neeg tau txais lossis tus neeg pub ntshav ua ntej hloov pauv. Kev ntsuam xyuas los txiav txim seb tus poj niam puas muaj Rh-positive lossis Rh-negative ntshav (Rh antibody titer) ua tiav thaum cev xeeb tub. Yog tias nws yog Rh-negative, cov kauj ruam tuaj yeem tiv thaiv tus menyuam.
DAT ua rau qhov zoo?
Muaj ntau yam ua rau DAT zoo, suav nrog cov tshuaj tiv thaiv hemolytic, kab mob hemolytic ntawm tus menyuam hauv plab thiabMe nyuam mos (HDFN), autoimmune hemolytic anemia (AIHA), thiab tshuaj tiv thaiv kab mob hauv tus neeg mob.
