Tsis tas li ntawd, 2 yam tseem ceeb ntawm cov ntshav yog dab tsi?
Cov khoom sib txawv uas ua rau ntshav. Plasma , cov qe ntshav dawb, cov qe ntshav liab, cov platelets.
Cov ntshav thiab qhov feem pua yog dab tsi?

Los ntawm ntim, cov cov qe ntshav liab suav txog 45% ntawm tag nrho cov ntshav , cov ntshav ntshav txog 54.3%, thiab dawb hlwb txog 0.7%.
