C-peptide, izwi kandi guhuza peptide, ni aside amine ikomeye mu musemburo wa insuline. Irekurwa na pancreas hamwe na insuline kandi ikora nk'ikimenyetso cyingenzi cyo gusuzuma imikorere ya pancreatic. Mugihe insuline igenga isukari mu maraso, C-peptide igira uruhare rutandukanye kandi ni ngombwa mu gusobanukirwa ubuzima butandukanye, cyane cyane diyabete. Mugupima urwego C-peptide, abatanga ubuvuzi barashobora gutandukanya diyabete yo mu bwoko bwa 1 na 2, kuyobora ibyemezo byo kuvura, no gukurikirana imikorere yubuvuzi.

Gupima urwego C-peptide ni ngombwa mugupima no gucunga diyabete. Abantu barwaye diyabete yo mu bwoko bwa 1 mubusanzwe bafite urugero ruke cyangwa rutamenyekana rwa insuline na C-peptide kubera sisitemu yumubiri yibasiye selile itanga insuline. Ku rundi ruhande, abantu barwaye diyabete yo mu bwoko bwa 2 barashobora kugira urwego rusanzwe cyangwa rwazamutse C-peptide kubera ko imibiri yabo itanga insuline ariko ikarwanya ingaruka zayo. Kugenzura urwego C-peptide ku barwayi, nk'abaterwa mu ngirabuzimafatizo ya islet, birashobora gutanga ubumenyi bw'ingenzi ku ntsinzi y'ubuvuzi.

Ubushakashatsi bwakoze kandi ubushakashatsi ku ngaruka zishobora gukingira C-peptide ku ngingo zitandukanye. Ubushakashatsi bumwe bwerekana ko C-peptide ishobora kuba ifite imiti igabanya ubukana ishobora gufasha kugabanya ingorane ziterwa na diyabete, nko kwangiza imitsi nimpyiko. Nubwo C-peptide ubwayo itagira ingaruka ku buryo butaziguye mu maraso ya glucose, ikora nka biomarker ifite agaciro mu gucunga diyabete no kudoda gahunda yo kuvura ibyo umuntu akeneye. Niba ushaka gucengera cyane gusobanukirwa diyabete, komezaamakuru yubucuruzibijyanye n'ubuvuzi n'iterambere ry'ubuvuzi birashobora gutanga ubumenyi bwingirakamaro kubanyamwuga n'abarwayi.
