Pali mitundu inayi yayikulu yamagazi: A, B, O, ndi AB. Mitunduyi imapangidwa ndi zinthu zomwe zili pamwamba pamaselo amwazi. Mtundu wina wamagazi umatchedwa Rh. Rh factor ndi mapuloteni pama cell ofiira amwazi. Anthu ambiri amakhala ndi kachilombo ka Rh; ali ndi Rh factor. Anthu opanda Rh alibe. Rh factor amabadwa kudzera mu majini.

Mukakhala ndi pakati, magazi ochokera kwa mwana wanu amatha kulowa m'magazi anu, makamaka pakubereka. Ngati mulibe Rh ndipo mwana wanu ali ndi Rh, thupi lanu lidzayankha magazi amwanayo ngati chinthu chachilendo. Idzapanga ma antibodies (mapuloteni) motsutsana ndi magazi a mwana. Ma antibodies amenewa nthawi zambiri samayambitsa mavuto panthawi yapakati.

Koma kusagwirizana kwa Rh kumatha kubweretsa mavuto m'mimba pambuyo pake, ngati mwanayo ali ndi Rh. Izi ndichifukwa choti ma antibodies amakhala mthupi lanu akangopanga. Ma antibodies amatha kuwoloka pa placenta ndikuukira maselo ofiira amwana. Mwanayo amatha kudwala matenda a Rh, vuto lalikulu lomwe lingayambitse kuchepa kwa magazi m'thupi.

Kuyezetsa magazi kumatha kudziwa ngati muli ndi Rh factor komanso ngati thupi lanu limapanga ma antibodies. Majekeseni a mankhwala otchedwa Rh immune globulin amatha kuteteza thupi lanu kuti lisapangitse ma Rh antibodies. Zimathandiza kupewa mavuto a Rh osagwirizana. Ngati chithandizo chofunikira kwa mwana, chingaphatikizepo zowonjezera kuti zithandizire thupi kupanga maselo ofiira amwazi komanso kuthiridwa magazi.
