There are many among us who have gone on to perform more than one pregnancy test just to be sure. This is considering the mere fact that you might be satisfied with the results of one. Now the question is are we crazy that we really find it hard to ascertain the results of one major test. Most of the hormone based tests go on to claim that they are 99 % accurate and the precision did vary from 54 % to 97 % which if you go on to analyse from the first date of the missed period. The first response test assumes to be the highest.

The main causes of a false negative test result (this does appear to be the case when you do become pregnant)
- One of the main reasons for a false negative could be that the test can be undertaken soon. This means that there is less amount of HCG in your urine. HCG goes on to form the placenta. This you cannot detect the fertilized attaches to the uterus and this takes place after a week of ovulation. If after conception you go on to undertake a pregnancy test it makes it really difficult to detect HCG.
What has to be done at this point of time? A general suggestion would be to wait for a week and then retake the test. You need to wait for 14 days till the date of your last sexual activity which may have led to conception. This would be more precise while opting for a home pregnancy test. This is all the more true if you are known to have irregular cycles or are not aware when did your last menstrual cycle take place.
- Hook effect- This is a complicated situation where you come across a situation where there is too much of HCG in your urine. If the levels are too high then the test will not be able to detect it. This is a very uncommon situation and you are likely to come across when you are having a molar pregnancy.
What is to be done if the results show negative and you have symptoms of pregnancy? It would be better to get in touch with your doctor.
