Can Pregnancy Tests Be Wrong?

Most of the pregnancy tests are about 97% accurate. A false negative can happen due to test errors

How common are false negative pregnancy for urine tests?

Follow the instructions of the pregnancy test. Read the result within the time frame given to avoid confusion. Don’t wait too long to read the result as it may provide a false negative result

If taken too early most likely you will have a false negative result.  It is possible that your hormone hCG in your system is too low to get a positive result, meaning there is not enough of the hormone hCG in the urine.

Levels of hCG decrease if you drink too much water, diluting your urine, so it is recommended to take the test in the morning as hCG concentration is higher when you held your urine for awhile.

Is it possible to test positive and not be pregnant?

A false positive pregnancy test can be devastating to people who are trying to conceive for a long period of time. Good thing, false positives are rare.

Some factors that may provide a false positive result:

• Reading the result beyond the time frame given on the instructions
• Expired pregnancy test kit
• Fertility medication increases hCG levels
• An early miscarriage

Do early pregnancy tests work?

Early pregnancy tests can never diagnose the presence of the hCG hormone until after implantation.

1. hCG is a hormone produced by the placenta
2. Placenta starts developing at the time of implantation
3. Implantation is the stage of pregnancy at which the embryo adheres to the wall of the uterus

How many days are required to confirm pregnancy?

A week after your missed period, however if you can’t wait until you’ve missed your period, wait at least a month or two after you last had sex.

• The body needs time to develop detectable hCG level, which takes to 7 – 12 days after successful implantation.
