What does ‘invalid’ mean on a pregnancy test?

How Does A Pregnancy Test Work?

You need to be aware of how tests function in detail before we discuss the results. All pregnancy tests work on the same basis.

Human chorionic gonadotropin, also known as hCG, is a hormone that they are looking for in your urine. This hormone is typically only produced by placental cells, so a woman can only have it when she is pregnant. After conception, your body begins to produce this hormone six to twelve days later.

What should I do after an invalid pregnancy test result?

Try once more, maybe with a different brand that’s simpler to use. You don’t have to wait until the morning to take a test; you can take one at any time of the day.

To ensure that there is enough urine for a result, keep the test in your urine stream for the recommended amount of time.

To ensure that you receive a result regardless of the test, it is best to adhere to the instructions in the packet.

What can affect a pregnancy test results?

Knowing when to take a pregnancy test in relation to the potential conception day is crucial. Human chorionic gonadotropin, or hCG, is a hormone that is measured by pregnancy tests and is produced by the placenta after a fertilized egg attaches to the uterine lining. Every day following conception, hCG levels rise, so the longer you wait to test, the more reliable and powerful the results will be. At 20mIU/hCG, or around 7 to 10 days after ovulation, Stix can detect hCG. However, we do advise taking the test at least three days before your missed period or 19 days after you had sex for the best outcomes. As your urine is more concentrated and likely to contain higher levels of hCG first thing in the morning, taking a test before you’ve had anything to drink will result in more accurate results.
