Zine iindidi zegazi eziphambili: A, B, O, kunye noAB. Iindidi zisekwe kwizinto ezikumphezulu weeseli zegazi. Olunye uhlobo lwegazi kuthiwa yiRh. I-Rh factor yiprotein kwiiseli ezibomvu zegazi. Uninzi lwabantu lune-Rh; bane-Rh factor. Abantu abangenayo i-Rh abanayo. I-Rh factor izuzwe njengelifa ngemfuza.

Xa ukhulelwe, igazi elivela kusana lwakho linokuwela kwigazi lakho, ngakumbi ngexesha lokuhanjiswa. Ukuba awunayo i-Rh kwaye umntwana wakho une-Rh, umzimba wakho uya kusabela kwigazi lomntwana njengesixhobo sasemzini. Iya kudala ii-antibodies (iiproteni) ngokuchasene negazi lomntwana. Ezi antibodies zihlala zingabangeli iingxaki ngexesha lokukhulelwa kokuqala.

Kodwa ukungahambelani kweRh kunokubangela iingxaki ekukhulelweni kamva, ukuba umntwana une-Rh-positive. Kungenxa yokuba izilwa-buhlungu zihlala emzimbeni wakho zakuba zenziwe. Amachiza omzimba anokuwela kwi-placenta kwaye ahlasele iiseli ezibomvu zegazi lomntwana. Usana lunokufumana isifo seRh, imeko enzulu enokubangela uhlobo olubi lwe-anemia.

Uvavanyo lwegazi lunokuxelela ukuba unayo i-Rh factor nokuba umzimba wakho wenze izilwa-buhlungu. Inaliti yeyeza elibizwa ngokuba yiRh immune globulin inokuwugcina umzimba wakho ungenzi iintsholongwane zeRh. Inceda ukuthintela iingxaki zokungahambelani kweRh. Ukuba unyango luyafuneka emntwaneni, lunokubandakanya izongezo zokunceda umzimba ukuba wenze iiseli ezibomvu zegazi kunye notofelo-gazi.
