Iqembu Igazi.

Iqembu igazi lomuntu luthathwe isici futhi inqunywa genotype abazali. Kukhona izinhlelo eziningana wamaqembu igazi. Ethandwa kakhulu iyona ABO, okuyinto kunqunywa izakhi zofuzo elihambisana.

Igazi yokwenza iqembu kuyadingeka ukuze sizuze ukumpontshelwa (igcwele abomvu egazi ne-plasma), kanye ukufakelwa imisebenzi. Noma yimuphi manipulation ezicutshini zomzimba womuntu zidinga ukuhambisana antigenic ofanayo, okuyinto kunqunywa uhlelo iqembu AB0.

Namuhla, kunezindawo ezimbili eziyinhloko (indlela) lapho ukuzimisela lwegazi. Zombili zingezakhe onokwethenjelwa. Esokuqala futhi iningi elula - igazi iqembu ukuphendula izogemagglyutinatsii. Okwesibili - indlela Cross (agglutinogens eyenziwa ekuboneni indlela yokuqala futhi eminye definition agglutinin usebenzisa i-erythrocyte ukumiswa). I ukushintshashintsha indlela yokuqala - Colyclons igazi eqenjini (ngokungafani kuya indlela sera ejwayelekile bangaveziwe ukungcoliswa Colyclons HIV kanye ne-hepatitis).

Ekwakhiweni izivivinyo sera izogemagglyutiniruyuschimi

Kulezi sera equkethwe agglutinins (amasosha omzimba) emaqenjini amane, okuyinto kunqunywa umsebenzi titer.

Lapho ukuxuba serum ngezimbobo nesineke sera ukucacisa iqembu agglutination waphawula lapho (omuhle ukusabela - kunenze nisondelane zama-erythrocyte kulandele flocculation, decolorized nge serum). Ukusabela okunge- kuboniswa iyunifomu color pink ngaphandle flocculation.

ukuhumusha imiphumela

Uma kulungiselelwa ukuphendula 3 serum ukunikeza ukusabela kabi ke - iqembu legazi O (I).

Ukuze O omuhle (I) kanye in (III) nemibi A (II) - Iqembu igazi (II).

Uma serum O (I) A no (II) - enhle, futhi (ii) - negative, iqembu Ngo (III).

Lapho bonke sera ezintathu ukunikeza ukusabela okuhle, iqembu legazi AB (IV). Esimweni esinjalo, kudingeka ukuba aqhube isifundo eyengeziwe nge serum legazi AB (IV) iqembu. agglutination Negative kuqinisekisa AB (IV) lwegazi.

Nge Colyclons lwegazi kunqunywa ngendlela efanayo. Umehluko omkhulu kusukela ejwayelekile Colyclons sera poliagglyutinatsii iyona sokungabi nhlobo erythrocyte ngenxa ukusabela non-ethize. Esinye isici esikhethekile tsoliklonalnyh ukusabela emaqenjini uphethwe AB0 - avidity okusezingeni eliphezulu (ie ezibukwayo Inkulumo agglutination). Uma eqhathaniswa ejwayelekile sera avidity Colyclons siphezulu, okwandisa ukunemba isethi amasampula.

Indlela yokunquma lwegazi ngokuyisisekelo kuyehla kube ekwakhiweni ethize agglutination ukusabela. On planchette (noma plate) kusetshenziswa ekhethekile imithombo Colyclons noma umutsi ejwayelekile, bese ngamunye wabo ungeze Amaconsi ambalwa egazi ihlolwa. Ukusabela itholwa ngaphakathi imizuzu emibili noma emithathu ne planchettes shaking (amapuleti) ne reagents. Njengoba kushiwo ngenhla - amafomu ishq ezinkulu okukhanyayo ukukhombisa ukusabela okuhle, ie khona antigen ojwayelekile serum amasosha omzimba kuleli qembu igazi.

Ngakho, ekutholweni zamaqembu egazi kuqondile futhi ukusabela kungenziwa iqhutshwe ukuhluka ezimbili eziyisisekelo inqubo. Khona-ke abakhululiwe ezilukhuni kunazo zonke kakhulu futhi enokwethenjelwa. Ukubaluleka kahle kutholakala ukuthi uphethwe yini igazi iqembu kuphezulu kakhulu, njengoba ukuba kucatshangelwe ngesikhathi ukumpontshelwa ehlukahlukene Ukufakelwa. Yingakho ngaphambi yimuphi operation kwenziwa isiteji amasampula ukucacisa iqembu igazi esigulini.
