Yog li, muaj yim hom ntshav muaj peev xwm:
- O tsis zoo Hom ntshav no tsis muaj A lossis B cov cim, thiab nws tsis muaj Rh factor.
- O zoo. Hom ntshav no tsis muaj A lossis B cov cim, tab sis nws muaj Rh factor.
- Qhov tsis zoo.
- Qhov zoo.
- B tsis zoo
- B zoo.
- AB tsis zoo
- AB zoo.
Ntawm no, hom ntshav sib txawv yog dab tsi?
Tib neeg ntshav yog pawg ua plaub hom : A, B, AB, thiab O. Txhua tsab ntawv hais txog hom antigen, lossis protein, nyob saum cov xim liab ntshav hlwb. Piv txwv li, qhov saum npoo ntawm liab ntshav cell hauv Hom A ntshav muaj antigens hu ua A-antigens.
Kuj Paub, dab tsi ua rau hom ntshav sib txawv ntawm ib leeg? ABO grouping system yog hais txog qhov sib txawv ntawm cov noob caj noob ces nyob rau hauv lub xub ntiag ntawm ob antigens (A thiab B), uas txhawb kev tsim cov khoom. txawv tshuaj tiv thaiv. Hom -O ntshav muaj ob qho tib si cov tshuaj tiv thaiv uas tsim nyob rau hauv yam -A thiab yam -B, as yam - AB no.
Ua kom pom qhov no, hom ntshav twg feem ntau yog dab tsi?
Muaj 4 pawg ntshav tseem ceeb: A, B, AB thiab O , ntawm pawg twg O yog qhov feem ntau. Hauv Tebchaws Meskas, qhov faib nruab nrab ntawm cov ntshav yog raws li hauv qab no: O-zoo : 38 feem pua. O -tsis zoo: 7 feem pua.
Dab tsi yog hom ntshav tsawg tshaj plaws?
Feem ntau, hom ntshav tsis tshua muaj neeg yog AB -tsis zoo thiab feem ntau yog O -zoo. Ntawm no yog kev sib cais ntawm hom ntshav tsawg tshaj plaws thiab ntau hom los ntawm haiv neeg, raws li American Red Cross.
