Current pregnancy tests are accurate, but there are a few reasons why the results can be wrong.Inaccurate results can arise due to a number of factors and are more likely with home urine pregnancy testing than with a blood test.There is always a chance the urine test kit you are using is defective and cannot accurately detect HCG in your urine.Consider buying a different brand and retest your urine if you think your results are wrong.If your early HPT is negative and you are anxious to know if you are pregnant, go see your doctor for a blood pregnancy test. The Office on Women's Health writes pregnancy tests are at least 99 percent accurate if the test is done correctly.However, an analysis of studies on the accuracy of home pregnancy test kits published in 1998 in the Archives of Family Medicine found user error was a significant cause of inaccurate results.It is more common to have a false negative result than a false positive one.

A few of these women can curiously have a false positive pregnancy test.
Some even have symptoms of pregnancy, including morning sickness, a growing belly, and subsequent false labor pains.
The abnormal pregnancy makes lower levels of HCG, which might be slow to detect.
The HCG level can subsequently increase and become detectable though more slowly than with a normal pregnancy.
