Ib yam li qhov muag lossis xim plaub hau, peb hom ntshav tau txais los ntawm peb niam thiab txiv. Txhua tus niam txiv txheeb ze pub ib ntawm ob tus noob ABO rau lawv tus menyuam. Cov noob A thiab B yog qhov tseem ceeb thiab O cov noob tau rov ua haujlwm. Piv txwv li, yog tias O gene tau ua khub nrog A gene, tus hom ntshav yuav yog A.
Tom qab ntawd, ib tus tseem tuaj yeem nug, Puas yog Menyuam mos ib txwm muaj leej txiv cov ntshav?
Tsis yog nws tsis. Tsis yog koj niam thiab txiv muaj rau muaj tib yam hom ntshav zoo li koj. Piv txwv li yog tias ib tus ntawm koj niam thiab txiv yog AB+ thiab lwm tus yog O+, lawv tuaj yeem ua tau muaj A thiab B cov menyuam. Hauv lwm lo lus, feem ntau tsis muaj leej twg ntawm lawv cov menyuam yuav koom nrog niam txiv hom ntshav.
Ib qho ntxiv, puas yog cov niam txiv dhau cov ntshav? Txhua yam lom niam txiv pub ib qho ntawm lawv ob ABO alleles rau lawv tus menyuam. Leej txiv leej twg yog hom ntshav AB ka dhau txawm yog A lossis B allele rau nws tus tub lossis tus ntxhais. Cov khub niam txiv no tuaj yeem muaj menyuam ntawm ib qho hom ntshav A (O los ntawm niam thiab A los ntawm txiv) lossis hom ntshav B (O los ntawm niam thiab B los ntawm txiv).
Ib yam li ntawd, nws tau nug, tus menyuam puas tuaj yeem muaj hom ntshav sib txawv dua li lawv niam lawv txiv?
Thaum a menyuam yuav muaj tib yam hom ntshav raws li ib qho ntawm nws / nws niam thiab txiv , nws tsis tshwm sim li ntawd. Piv txwv li, niam txiv nrog AB and AW hom ntshav tuaj yeem ua tau ib yam muaj menyuam nrog hom ntshav A los yog hom ntshav B. Ob qho no hom yog twv yuav raug hu txawv dua niam txiv ' hom ntshav ! Lawv yuav sib tw ob niam txiv.
Puas yog O+ thiab O+ muaj menyuam?
Qhov ntawd txhais tau tias txhua tus menyuam ntawm cov niam txiv no muaj muaj 1 hauv 8 txoj hauv kev muaj me nyuam nrog rau hom O-ntshav. Txhua tus ntawm lawv cov me nyuam yuav thiab muaj ib 3 in8zv muaj A+, 3 hauv 8 txoj hauv kev los ua O+ , thiab muaj 1 hauv 8 txoj hauv kev los ua A-. A+ niam txiv thiab ib tus O+ niam txiv tau mas muaj ib O- menyuam.

Cov tshuaj twg dhau los ua ntej dhau cov metabolism?
Thawj kis cov metabolism tuaj yeem tshwm sim hauv lub siab (rau propranolol, lidocaine, chloromethiasole thiab GTN) lossis hauv lub plab (rau benzylpenicillin thiab insulin). Tom qab cov tshuaj tau nqos, nws tau nqus los ntawm lub plab zom mov thiab nkag mus rau hauv lub cev hepatic portal

Cov ntshav hom twg tuaj yeem tau txais kev tso ntshav hom A ruaj ntseg?
Qhov tseem ceeb tshaj ntawm cov no yog ABO thiab RhD. Kev hloov pauv nrog ABO cov ntshav tsis sib haum tuaj yeem ua rau muaj qhov tshwm sim hnyav thiab muaj peev xwm ua rau tuag taus.
