Yog tias thaum ECO hCG tsis tshua muaj, uas yog tsawg dua 25 mE / ml, qhov no qhia tau hais tias lub tswv yim tsis tshwm sim. Tsis tas li ntawd, tus nqi qis ntawm qhov ntsuas tau qhia tau hais tias tsis raug nyob rau hauv kev muab xam ntawm lub sij hawm gestation, thaum txiav txim siab hCG dhau lawm.
