Can diluted urine cause a false positive pregnancy test?
Don’t Drink A Lot Of Water Before Taking The 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. This way, you’ll avoid diluting your hCG level and getting a false ‘Not Pregnant’ result.

What can affect a urine pregnancy test?
Home pregnancy tests work by detecting the presence of human chorionic gonadotropin (hCG) in a urine sample. There are a few things that can cause a false negative reading, namely the improper use of the test, testing too early, using an expired test, or diluting the urine by drinking too much water in advance.
Can I take a pregnancy test with any pee?
Pregnancy tests look for a special hormone – human chorionic gonadotropin (hCG) – that only develops in a woman’s body during pregnancy. These tests can use either your urine or blood to look for hCG.
What happens if you mix water and pee for a pregnancy test?
After peeing in a cup, add a few tablespoons of water to your urine so it becomes lighter in color. This might work because it reduces how much hCG you have in your urine. You’ll still have enough of this hormone for the pregnancy test to “read,” but not so much that it’s overwhelmed.
What happens if you wet a pregnancy test with water?
Presumably, water will give a negative result (we hope!), but you still can’t then add your urine to the strip as well. If you reuse a strip that has gotten wet — either with water or urine and even if it’s dried — you may get a false positive. That’s because as an HPT dries, an evaporation line can appear.
Can you mess up a pregnancy test?
Not reading the instructions
It is important to read the pregnancy test instructions prior to even starting the test. Failure to do this can cause you to mess it up, particularly if you are just assuming that the test you bought will work the same way as other tests you’ve used in the past.
Is a faint line on a pregnancy test positive?
A faint line on a pregnancy test probably means that it’s very early in your pregnancy. Even a faint positive pregnancy test indicates that you have some of the pregnancy hormone human Chorionic Gonadotropin (hCG) in your system.
Can I be 5 weeks pregnant and still test negative?
Even if you did miss your period but it hasn’t been at least a couple of weeks since you conceived, you could still get a “false negative.” That’s because you need a certain level of a hormone called HCG (human chorionic gonadotropin) in your urine for the test to work.
Can a clear blue positive test be wrong?
Most home pregnancy tests are reliable, for example Clearblue’s tests have an accuracy of over 99% from the day you expect your period, and while it’s possible a test showing a negative result is wrong, particularly if you’re testing early, getting a false positive is extremely rare.
Why do I feel like I’m pregnant but the test says negative?
If you feel pregnant but had a negative test result, you may have experienced a very early miscarriage (also known as a chemical pregnancy). This occurs when there is a problem with the fertilized egg, most commonly a chromosomal disorder that makes the pregnancy non-viable.
