The quantitative hCG test is one of the most accurate tests for confirming pregnancy. However, it has also been known to give false-positive or false-negative results. If the quantitative hCG test is performed too soon in the pregnancy when the body has not had the chance to produce enough amounts of the hormone, one may receive a negative result despite being pregnant, while there are several conditions like germ cell tumours, certain cancers, etc. that can elevate the hCG levels, resulting in a positive report even when one is not pregnant. A doctor can prescribe further tests as a follow-up to clear any doubt.
