Patient discussion about HI test

Q. hi everyone……I would like to ask everyone how reliable are the self tests that are being carried out for this. hi everyone……I would like to ask everyone how reliable are the self tests that are being carried out for pregnancy? I did try few at home and results are negative but I can see that my symptoms are pretty positive...……. Should I visit the doctor or can I rely on the test that I did myself?

A. They are very reliable, however if they are done too soon or not done properly they can be negative when there is actually a pregnancy. However, they will NOT give a positive if there is NOT a pregnancy.

The best time to take the test is first thing in the morning and using the first urine of the day. It contains the highest level of the pregnancy hormones.
