Lub neej hacker xam pom tias cov ntaub so ntswg ua pa nyob ntawm cov xim nrog hlau.

Dab tsi yog hemoglobin

Hemoglobin Fetal hemoglobin yog qhov tsawg dua rau DNA cleavage piv rau cov neeg laus cov protein (Hb) yog cov pigment protein uas muaj hlau ions. Nws muaj peev xwm ntawm oxidizing. Qhov no txhais tau hais tias oxygen atoms txuas nrog cov hlau. Hemoglobin thauj lawv mus rau cov ntaub so ntswg rau cov hlwb siv rau kev ua pa. Yog tias tsis muaj xim txaus, lub cev yuav pib ua haujlwm tsis raug.

Dawb hemoglobin yog tshuaj lom thiab tuaj yeem ua rau lub cev puas tsuaj. Yog li ntawd, nws muaj nyob rau hauv erythrocytes, cov qe ntshav liab.

Dab tsi yog hemoglobin

Nws tuaj yeem sib txawv hauv cov qauv. Lub peev xwm ntawm hemoglobin los khi rau oxygen nyob ntawm qhov no. Cov kws tshawb fawb tau tshawb pom ntau hom hemoglobin Electrophoresis, thiab tsis yog txhua tus ntawm lawv yuav tsum nyob hauv tus neeg noj qab haus huv:

• Hb A yog ib qho Sickle Cell Tests pigmented iron-muaj protein ntau uas tshwm tom qab yug me nyuam thiab tseem nyob mus ib txhis.
• Hb F yog fetal hemoglobin uas tuaj yeem nqa oxygen ntau dua li cov protein hauv cov laus. Feem ntau, tus me nyuam hauv plab muaj nws thaum lub sij hawm kev loj hlob ntawm intrauterine, tab sis tom qab yug me nyuam nws tus nqi txo hemoglobin Electrophoresis mus rau 50-80%, los ntawm rau lub hlis - mus txog rau 8%, thiab tom qab rau lub hlis ntawm lub neej, tsis ntau tshaj 1-2% ntawm xws li hemoglobin. seem.
• Hb S yog cov xim uas hloov cov qauv molecular, yog li ntawd, xws li hemoglobin nqa oxygen tsawg dua Hb A. Cov protein no tshwm sim hauv cov kab mob ntshav qab zib, cov kab mob tshwj xeeb hauv cov ntshav, yog li nws yuav tsum tsis txhob ua li qub.
• Hb C yog ib hom kab mob ntawm hemoglobin uas tau txais los. Cov txheej txheem no tuaj yeem ua rau kev loj hlob ntawm hemolytic Hemoglobin C Disease anemia, thaum cov qe ntshav liab raug rhuav tshem.
• Hb A1c yog ib hom protein uas tshwm sim hauv Hemoglobin A1C (HbA1c) Test rau cov neeg mob ntshav qab zib. Nws tseem hu ua glycosylated hemoglobin vim tias nws tsim cov ntawv cog lus muaj zog nrog cov piam thaj thiab tsis tshua muaj oxygen.

Dab tsi yog qhov ntsuas ntawm hemoglobin hauv cov ntshav

Nws nyob ntawm poj niam txiv neej thiab hnub nyoog. Cov kws kho mob ua raws li cov txiaj ntsig hemoglobin hauv qab no:

• cov txiv neej hnub nyoog tshaj 18 xyoo - 140-175 g / l;
• cov poj niam hnub nyoog tshaj 18 xyoo - 123-153 g / l;
• Cov menyuam yug tshiab Anemia ntawm cov menyuam yug tshiab kev kuaj mob, kev tiv thaiv, kev kho mob ntawm 1-2 lub lis piam ntawm lub neej - siab dua 150 g / l;
• cov menyuam mos ntawm 3-4 lub lis piam - ntau dua 120 g / l;
• cov menyuam yaus hemoglobin concentration rau kev kuaj mob ntshav qab zib thiab kev ntsuas ntawm nws qhov hnyav txog 59 lub hlis - siab dua 110 g / l;
• cov menyuam hnub nyoog 5-11 xyoos - siab dua 115 g / l;
• cov menyuam yaus hnub nyoog 12-18 xyoo - siab dua 120 g / l.

Yuav ua li cas paub koj qib hemoglobin

Cov kws kho mob tshawb xyuas hemoglobin Test nrog cov ntshav ua tiav. Feem ntau nws raug coj los ntawm tus ntiv tes txhua lub sijhawm yam tsis muaj kev npaj tshwj xeeb. Thiab nyob rau hauv cov me nyuam mos liab, pob taws yog punctured kom tau txais cov ntshav kuaj. Cov txiaj ntsig kev tshawb fawb tau npaj tiav hauv ob peb teev.

Yuav ua li cas yog tias qib hemoglobin txawv txav

Hemoglobin tuaj yeem nce lossis txo qis, qhov tom kawg yog ntau dua thiab hu ua anemia. Txhawm rau nrhiav cov laj thawj ntawm kev hloov pauv, koj yuav tsum mus ntsib tus kws kho mob. Tus kws kho mob yuav xaj kom kuaj ntxiv. Piv txwv li:

• Hematocrit lossis Hematocrit. Qhov no yog ib qho qhia txog qhov sib piv ntawm qhov ntim ntawm cov qe ntshav liab mus rau tag nrho cov ntshav plasma Cheebtsam.
• Iron Iron Tests Research. Tshawb xyuas cov ntshav cov hlau, cov proteins ferritin thiab transferrin, nrog rau tag nrho cov hlau tsis muaj peev xwm khi rau cov ntshav.
• Haptoglobin Haptoglobin. Qhov no yog lub npe ntawm kev tsom xam rau cov protein uas pab hloov hemoglobin, uas yog sab nraud cov qe ntshav liab.
• Hemoglobinopathy Electrophoresis Kev Ntsuam Xyuas ntawm hemoglobin. Siv los txheeb xyuas hom hemoglobin txawv txav.
