Hematocrit txo qis tus me nyuam - qhov ua rau
Raws li lub ntsiab txhais, peb tuaj yeem xav tias tus nqi ntsuas ntawm qhov hematocrit txo nrog tus thawj ntawm cov erythrocytes hauv cov ntshav ntawm tus menyuam. Tus hematocrit yog xav tias yuav raug txo kom tsawg ntawm 20-25% thiab qhov no yuav ua rau muaj cov teeb meem:
- ncua kev tsim ntawm erythrocytes hauv cov pob txha pob txha;
- ib qho kev nce nyob rau hauv tus nqi ntawm kev puas tsuaj ntawm erythrocytes nyob rau hauv cov ntshav;
- nce ntshav ntim rau hauv tus menyuam;
- nce nyob rau hauv lub concentration ntawm proteins nyob rau hauv cov ntshav (hyperproteinemia);
- ntshav thinning (hyperhydration);
- mob ntshav;
- anemia.
Nws yuav tsum tau muab sau tseg tias ib qho qhia tau tias tsawg ntawm cov tshuaj tua kab mob tsawg tsis tuaj yeem tham txog qhov muaj teeb meem hauv tus menyuam lub cev.
