What can cause a False Pregnancy Positive Test?

Incorrect Testing Method

However, sometimes when a test sample is kept for too long after the stipulated period a faint line displaying a positive pregnancy test can appear. Also sometimes women tend to reaffirm the test and look at it after the time of testing is over. In all probably a second faint line might appear on the test kit making the woman believe that she is pregnant.


Evaporation lines on Pregnancy Tests

An evaporation line on a pregnancy test can also cause a false positive pregnancy test. An evaporation line occurs on a home pregnancy test kit when the urine sample begins to dry on the test kit. It is most often taken as a positive pregnancy test. The best way to not let this evaporation line and a false positive test fool you is to check for the result within the stipulated time as mentioned in the pregnancy test at home kit. However, do see a doctor if you see an evaporation because sometimes a low level of human chorionic gonadotropin or hCG in the body can cause a faint li8ne resembling a positive test to appear.

Some diseases of the liver, cancers such as choriocarcinoma that is an extremely rare type of cancer found in the uterus can cause the hCG level in the body to shoot up. Some types of breast cancers and ovarian cancers can also cause a false positive pregnancy test.

Medications that can cause a False Positive Pregnancy Test

Women who are undergoing fertility treatment and hCG therapy might get a false positive pregnancy test. Medicines such as phenothiazine can cause a false positive pregnancy test. These medicines interfere with the hCG level in the body.
