The consensus online among frequent testers is that pink dye tests are the best overall option. Many people believe that, compared to their blue counterparts, pink dye tests are less prone to getting an evaporation line.
Can you trust blue dye pregnancy tests?
The blue dye tests have been known to be more likely to give you an evaporation line than the pink dye tests. You can also only read the result within the time limit! Each brand of pregnancy test should indicate on the box when the test results should be read.
What pregnancy tests detect the lowest amount of hCG?
One kit, the First Response Early Result Pregnancy Test, emerged as the most reliable and sensitive test. “It detected hCG at concentrations as low as 6.5 mIU/ml (thousandths of an International Unit per milliliter) – that’s almost sensitive enough to detect any pregnancy soon after implantation,” CR wrote.
Does clear blue have pink dye tests?
So excited Clear Blue has finally come out with a pink line test.
What color is the pregnancy test for positive?
In early pregnancy, there may be very little hCG in the urine, and the positive line may be faint. Even a faint positive line has color, and this distinguishes it from an evaporation line, which is colorless. Any coloration in a positive line indicates that a woman is pregnant.
Can a pregnancy test turn positive overnight?
This usually ranges between a couple of minutes up until 10 minutes later. If you see a positive result beyond this time frame, you may be left second-guessing the results. However, the false-positive reading, in this case, is due to something called an evaporation line.
When does your body start producing hCG?
A woman’s body begins to produce hCG from cells in the developing placenta (tissue that nourishes a growing fetus) soon after implantation of a fertilized egg inside the uterus. Around eight days after ovulation, trace levels of hCG can be detected from an early pregnancy.
What happens if you pee too much on a pregnancy test?
The hook effect happens when you have too much hCG in your blood or urine. How is this possible? Well, the high levels of hCG overwhelm the pregnancy test and it doesn’t bond with them correctly or at all. Rather than two lines saying positive, you get one line that incorrectly says negative.
How sensitive are clear blue dye tests?
Results: First Response Early Result had an analytical sensitivity of 6.3 mIU/mL, which was estimated to detect greater than 95% of pregnancies on the day of missed period. The sensitivity of Clearblue Easy Earliest Results was 25 mIU/mL, which indicated detection of 80% of pregnancies.
