Does Clearblue give false negatives?
Know this: All Clearblue® pregnancy tests are over 99% accurate from the day you expect your period. False positives very rarely occur, and are often due to medical conditions or certain medications. False negatives, while more common, typically occur due to testing too early or drinking too much liquid before testing.
What are the odds of a false-negative pregnancy test?
Home pregnancy tests are usually accurate, but researchers estimate that up to 5% of tests give a false negative — meaning the test says you aren’t pregnant when you actually are. There are a few reasons why you might get a false negative. You might be taking the test too early or after drinking too much water.
How can you get a false positive on a Clearblue pregnancy test?
A test will only show a false positive if you have hCG in your system for another reason such as you were recently pregnant, are taking fertility medications containing hCG, or if you have a medical condition, like some rare ovarian cysts.

Can a pregnancy test come up negative if I didn’t pee enough? A false negative on a home pregnancy test is possible, but extremely unlikely. As long as your urine got on the test’s absorbent strip, it should be accurate.

Are Clear Blue tests more sensitive?
If a Clearblue Pregnancy Test is used from the day the period is due, it is more than 99% accurate in detecting pregnancy. The high sensitivity of Clearblue Pregnancy Tests means that pregnancy can be detected up to 6 days before the missed period for women who wish to test early.
Can peeing too much on a pregnancy test affect the results?
Excess fluids can impact the accuracy of the test results, so if your urine is diluted or pale yellow, hold off on taking a test. Diluted urine tends to also have diluted hCG levels which can skew the test results. Take a test when you naturally need to pee.
