Understanding Unusual Home Pregnancy Test Results: Blue Line Explained

A solid blue vertical line in the square window and a negative circle window on a home pregnancy test usually means that the test is invalid. This can happen for a number of reasons, such as:

* The test was not performed correctly. Make sure that you followed the instructions on the test package carefully.

* The test is expired. Check the expiration date on the test package to make sure that it is still valid.

* The test is defective. If you think that the test may be defective, contact the manufacturer.

If you are still not sure what the results of your home pregnancy test mean, you should talk to your doctor.
