• Yadda akeyin gwajin mahaifin
• Gwajin DNA yayin ciki
• Inda za a yi gwajin mahaifin

Gwajin mahaifin wani nau'i ne na gwajin DNA wanda yake da nufin tabbatar da matsayin dangi tsakanin mutum da mahaifinsa da ake tsammani. Ana iya yin wannan gwajin yayin ciki ko bayan haihuwa ta hanyar nazarin jini, yau ko igiyar gashi na uwa, yaro da uba da ake zargi.

Babban nau'ikan gwajin mahaifin sune:

• Gwajin haihuwa na haihuwa: ana iya yin shi daga mako na 8 na ciki ta amfani da ƙaramin samfurin jinin uwa, tunda ana iya gano DNA ɗin tayi a cikin jinin uwar, kuma idan aka kwatanta shi da abin da ake zargi na mahaifin;
• Amniocentesis gwajin uba: ana iya yin shi tsakanin ranar 14 da 28 na ciki ta hanyar tattara ruwan amniotic da ke kewaye da tayi da kuma kwatanta shi da abin da ake zargin mahaifinsa da shi;

Yadda akeyin gwajin mahaifin

Ana yin gwajin mahaifin ne daga nazarin samfurin da aka aika dakin gwaje-gwaje, inda ake gudanar da gwaje-gwajen kwayoyin da ke nuna matsayin dangi tsakanin mutanen da aka yi wa gwajin ta hanyar kwatanta DNA. Learnara koyo game da gwajin DNA.

Sakamakon gwajin mahaifa ana sakashi tsakanin sati 2 zuwa 3, ya danganta da dakin binciken da aka yi shi, kuma abin dogaro ne 99.9%.

Gwajin DNA yayin ciki

Ana iya yin gwajin DNA a lokacin daukar ciki daga mako na 8 na ciki ta tattara jinin uwa, tunda a wannan lokacin ana iya samun DNA na tayi tana zagayawa a cikin jinin uwa. Koyaya, lokacin da gwajin DNA ya gano DNA na uwa, yana iya zama dole a sake tattara shi ko jira aan makonni kaɗan don tattara sauran kayan.

Yawancin lokaci a cikin mako na 12 na ciki, ana iya tattara DNA ta hanyar chorionic villus biopsy, wanda a ciki ne ake tattara samfurin ɓangaren mahaifa wanda ke ɗauke da ƙwayoyin tayi, ana ɗauka don bincike a cikin dakin gwaje-gwaje da kuma kwatanta su da kayan halittar tayi.ya kamata uba. Game da makon 16 na ciki, za a iya tattara ruwan amniotic kuma kusan mako na 20, jini daga igiyar cibiya.

Kowace hanya ake amfani da ita don tattara kayan halittar haihuwa, ana kwatanta DNA da mahaifin DNA don kimanta matsayin dangi.

Inda za a yi gwajin mahaifin

Za'a iya yin gwajin mahaifin kansa ko ta hanyar umarnin kotu a cikin dakunan gwaje-gwaje na musamman. Wasu dakunan gwaje-gwaje da ke yin gwajin haihuwa a Brazil sune:
