Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Rh factor, inozivikanwawo seRh D antigen, inonzi antigen inowanikwa pamasero matsvuku eropa; vanhu vane Rh-positive (Rh+) vane antigen iyi pamasero avo matsvuku eropa uye vanhu vane Rh-negative (Rh<unk>) havana. Mukati mokubereka kwomuzvarirwo, kukuvadzwa kwokubereka kana kuti zvinetso mukati mokubata pamuviri, ropa rinobva muchibereko rinogona kupinda mumuviri waamai. Muchiitiko chaamai nomwana vane Rh- isingawirirani, kusanganiswa kweropa kunotevera kunogona kuita kuti amai vane Rh- vanzwe Rh antigen iri pamasero eropa remwana ane Rh+ zvichiita kuti pamuviri pasare nguva yakawanda, uye pamuviri chero kupi zvako kunotevera, pave nengozi yechirwere chehemolytic chemucheche achangoberekwa. Anti-RhD antibodies inopiwa sechikamu chechirongwa chokurapa mwana asati aberekwa kuti kudzivirirwe kunzwisisika kunogona kuitika apo amai vane Rh- negative vane mwana ane Rh- positive. Kurapa amai nemishonga inorwisa Rh antibodies vasati vakuvara uye vachangoberekwa kunoparadza Rh antigen iri mumuviri waamai kubva kumwana ari mudumbu. Zvinokosha kucherechedza kuti izvi zvinoitika antigen isati yakwanisa kukurudzira masero aamai B kuti "ayeuke" antigen yeRh nokugadzira masero aB anoyeuka. Nokudaro, gadziriro yake yomuviri yokudzivirira zvirwere haizogadziri masoja anorwisa Rh, uye haizorwisi maantigen eRh evana vari kuberekwa iye zvino kana kuti vanouya. Rho(D) Kurapa neImmune Globulin kunodzivisa kuita kuti munhu anzwe chirwere chinogona kukonzera chirwere cheRh, asi hakudzivisi kana kurapa chirwere chacho.  Mubvunzo: Chii chinogadzirwa neRh antigen?
