Home pregnancy tests, which can be obtained from practically any pharmacy, are pretty reliable. In fact, most of them can detect pregnancy with an accuracy of 97%, even from the day after one's menstrual period. The tests work by indicating if the pregnancy hormone (human chorionic gonadotropin) is present in the urine.
But, as with anything else, certain medical or environmental conditions can alter the result and lead to a "false positive." The most common are:
1. Ovary diseases such as PCOD or PCOS
Polycystic ovarian syndrome consists of the development of cysts on the ovaries. These cysts are groups of featureless tissues which affect the functioning of the ovaries. Ovarian cysts can produce hCG even without pregnancy. The hormone is detected in the urine and can give a false positive reading on a pregnancy test.
