Cov ntaub ntawv pov tseg no yog qhia tshwj xeeb rau cov txheej txheem ntshav hloov cov txheej txheem. Cov txheej txheem sib txuas ua ntej ua kom yooj yim rau cov txheej txheem teeb tsa, txo qhov peev xwm rau tib neeg yuam kev thiab paug. Nws yog sib xws nrog DOLINGA90 lub kaw-voj, cia rau kev sib koom ua ke hauv kev sib xyaw thiab sib cais ntawm ntshav. Cov teeb tsa yog tsim los ua haujlwm sib haum nrog lub tshuab ceev ceev Centrifugation txheej txheem, kom sib cais ua kom muaj zog thiab nyab xeeb ntawm kev ncaj ncees ntawm lwm cov ntshav.
Cov qauv sib txuas ua ntej ntawm cov chaw pov tseg tsis tsuas yog txuag sijhawm tab sis kuj tseem muaj kev pheej hmoo tsis huv, uas yog qhov tseem ceeb hauv Plasma pauv cov txheej txheem. Cov teeb tsa yog tsim nrog cov khoom uas yog maj mam rau ntshav thiab lwm yam ntsiab lus cell yog tshwj tseg hauv lawv lub xeev zoo. Qhov no pab kom ua kom muaj txiaj ntsig zoo ntawm cov txheej txheem ntshav sib pauv thiab txo qhov kev pheej hmoo ntawm kev phom sij. Ib qho ntxiv, cov teeb tsa tau tsim rau kev tuav yooj yim thiab pov tseg, ntxiv txhim kho tag nrho cov neeg siv khoom thiab kev nyab xeeb.
