You asked: Is blue or pink dye pregnancy test better?

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.

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 the color of a pregnancy test matter?

When taking a pregnancy test, any line in the test indication area is considered a positive pregnancy test, even if it is lighter than the control line. The darker line is usually the control line.

Is clear blue ever 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.

Can 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.

When does your body start producing hCG?

One thing that happens very quickly is production of hCG. This chemical is only found in pregnant women and it starts to build up once the fertilized egg implants in the uterus (womb) — about 10 days after conception.

How long does it take for hCG to reach 25 mIU?

Urine hCG concentrations reach 10 to 25 mIU/mL by 7 to10 days after conception. Urine pregnancy tests have a sensitivity of 90% to 97% and a specificity of 99% for pregnancy during the first week after a missed menstrual period.

Why am I only getting faint positives?

You’re pregnant

Some women see a clearly distinguishable positive line after taking a home test. But in other cases, the positive line appears faded. In these instances, a faint positive can be caused by low levels of the pregnancy hormone human chorionic gonadotropin (hCG).
