Isifinyezo

Kunezinhlobo ezine ezinkulu zegazi: A, B, O, no-AB. Izinhlobo zisuselwa ezintweni ezingaphezulu kwamaseli egazi. Olunye uhlobo lwegazi lubizwa ngeRh. I-Rh factor yiprotheni emangqamuzaneni abomvu egazi. Abantu abaningi bane-Rh; bane-Rh factor. Abantu abangenayo i-Rh abanayo. I-Rh factor izuzwa ngofuzo.

Uma ukhulelwe, igazi elivela enganeni yakho lingangena egazini lakho, ikakhulukazi ngesikhathi sokubeletha. Uma ungenayo i-Rh futhi ingane yakho ine-Rh, umzimba wakho uzosabela egazini lengane njengento engaziwa. Izokwakha amasosha omzimba (amaprotheni) alwa negazi lengane. Lawa masosha omzimba ngokuvamile awazibangeli izinkinga ngesikhathi sokukhulelwa kokuqala.

Kodwa ukungahambelani kwe-Rh kungadala izinkinga ekukhulelweni kamuva, uma ingane ine-Rh. Lokhu kungenxa yokuthi ama-antibody ahlala emzimbeni wakho uma esekhile. Ama-antibody angawela i-placenta futhi ahlasele amangqamuzana egazi abomvu engane. Ingane ingathola isifo i-Rh, isimo esibi esingadala uhlobo olubi lwe-anemia.

Ukuhlolwa kwegazi kungasho ukuthi unayo yini i-Rh factor nokuthi umzimba wakho unawo yini amasosha omzimba. Imijovo yomuthi obizwa nge-Rh immune globulin ingavimbela umzimba wakho ekwenzeni ama-Rh antibodies. Kuyasiza ukuvimbela izinkinga zokungahambelani kwe-Rh. Uma kudingeka ukwelashwa kwengane, kungafaka izithasiselo zokusiza umzimba ekwenzeni amangqamuzana abomvu egazi nokumpontshelwa igazi.
