Siab lossis qis hemoglobin: nws txhais tau li cas thiab siv qhov tseem ceeb

Zoo Siab

• Glycated hemoglobin
• Hemoglobin hauv kev tso zis

Hemoglobin, lossis Hb, yog lub cev tiv thaiv cov ntshav liab thiab nws lub luag haujlwm tseem ceeb yog thauj oxygen mus rau cov ntaub so ntswg. Hb muaj cov pab pawg heme, uas yog tsim los ntawm hlau, thiab cov saw caj dab, uas tuaj yeem yog alpha, beta, gamma lossis delta, uas ua rau muaj ntau hom hemoglobin, xws li:

• HbA1, uas yog tsim los ntawm ob lub dag zog alpha thiab ob txoj sia txuas thiab tam sim no muaj kev cuam tshuam ntau dua hauv cov ntshav;
• HbA2, uas yog tsim los ntawm ob lub alpha chains thiab ob qho txuas raws;
• HbF, uas yog tsim los ntawm ob lub alpha chains thiab ob lub gamma chains thiab yog tam sim no muaj kev kub siab ntau dua hauv cov menyuam yug tshiab, nrog lawv cov concentration poob qis raws li kev txhim kho.

Ntxiv rau cov hom tseem ceeb no, tseem muaj Hb Gower I, Gower II thiab Portland, uas muaj nyob hauv lub neej embryonic, nrog lawv qhov kev txo qis thiab nce hauv HbF raws li kev yug menyuam.

Glycated hemoglobin

Glycated hemoglobin, tseem hu ua glycosylated hemoglobin, yog cov kev kuaj mob uas lub hom phiaj los kuaj xyuas cov ntshav qabzib hauv kev kho mob hauv cov ntshav hauv 3 lub hlis, ua tau zoo heev rau kev kuaj mob thiab saib xyuas ntshav qab zib, nrog rau kev ntsuas nws qhov hnyav.

Tus nqi qub ntawm glycated hemoglobin yog 5.7% thiab ntshav qab zib tau paub meej thaum tus nqi sib npaug lossis ntau dua 6.5%. Kawm ntxiv txog glycated hemoglobin.

Hemoglobin hauv kev tso zis

Piv txwv li, hemoglobin nyob rau hauv cov zis yog hu ua hemoglobinuria thiab feem ntau yog qhia txog kev mob raum, mob npaws lossis lom taug txhuas. Kev txheeb xyuas hemoglobin hauv cov zis yog ua tiav los ntawm kev kuaj zis yooj yim, hu ua EAS.

Ntxiv nrog rau hemoglobin, hematocrit tseem ceeb kuj qhia txog cov kev hloov pauv hauv cov ntshav xws li ntshav liab thiab ntshav roj. Saib seb hematocrit yog dab tsi thiab yuav ua li cas to taub nws tshwm sim.
