False negative pregnancy tests and what causes them
If you take a home pregnancy test too early, you may get a false negative result. A false negative result is when the test says you are not pregnant but you are. This can be misleading and when using home pregnancy tests you must be very careful of avoiding any factors that may cause false results.
There could be various reasons for a false negative test.

There could be various reasons for a false negative test.
- Early Detection Attempt
- One reason for a false negative pregnancy test could be that you took the test too early. Pregnancy tests vary in their sensitivity which means how soon they can detect the hormone Human Chorionic Gonadotropin (hCG) in your urine. It is possible that although your ovum might be fertilized, meaning you may be pregnant, but your body has not started secreting enough Human Chorionic Gonadotropin (hCG) for the test to measure. Your body needs time for the hormone to rise to a high enough level to be detected in a test.
- Erratic Technique
- There is a possibility that while using the home pregnancy test strip you either did not dip it well or did not hold it well in your urine stream. This error in technique may give false negative results.
- Missed Reaction Time
- For accuracy in home pregnancy tests it is essential that you read the test results in the stipulated reaction time. If you let the test sit for too long (after the instructions on the box tell you), the test is invalid. This may cause it to show false negative results.
