Le khithi isetshenziswa ekutholweni kwekhwalithi ye-in vitro ye-polymorphism ye-CYP2C9*3 (rs1057910, 1075A>C) ne-VKORC1 (rs9923231, -1639G>A) ku-DNA ye-genomic yamasampuli egazi lonke lomuntu.
Le kit isetshenziselwa ukutholwa kwekhwalithi ye-in vitro ye-polymorphism ye-CYP2C19 yofuzo i-CYP2C19*2 (rs4244285, c.681G>A), CYP2C19*3 (rs4986893, c.636G>A), CYP2C19*20 c1485 (rs168) >T) ku-DNA ye-genomic yamasampula egazi eliphelele lomuntu.
Le kit isetshenziselwa ukutholwa kwekhwalithi ye-DNA kuma-antigen subtypes e-leukocyte yabantu i-HLA-B*2702, HLA-B*2704 kanye ne-HLA-B*2705.
Le khithi isetshenziselwa ukuthola izindawo ezi-2 zokuguqulwa kofuzo lwe-MTHFR.Ikhithi isebenzisa igazi eliphelele lomuntu njengesampula lokuhlola ukuze linikeze ukuhlolwa kwekhwalithi kwesimo soguquko.Ingasiza odokotela ukuthi baklame izinhlelo zokwelashwa ezifanele izici zomuntu ngamunye kusukela ezingeni lamangqamuzana, ukuze kuqinisekiswe impilo yeziguli ngezinga elikhulu kakhulu.
