What is wrong with blue dye pregnancy tests?

Are blue dye pregnancy tests reliable?

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 causes a dye run on a pregnancy test?

Only urine that contains a sufficient level of hCG can cause the test’s dye to stain in a way that shows a positive result. In early pregnancy, there may be very little hCG in the urine, and the positive line may be faint.

Can you mess up a Clear Blue pregnancy test?

And while they do pretty well at what they’re supposed to do — detect the pregnancy hormone human chorionic gonadotropin (hCG) — to get accurate results, you need to follow package instructions as written. So no, you can’t reuse a pregnancy test.

Can you get a very faint positive pregnancy test?

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. Your body starts producing hCG right after implantation.

Can a pregnancy test go from negative to positive overnight?

After getting a negative result on a home pregnancy test, it’s fair to conclude that you’re not pregnant. However, if you happen to glance back at the test later in the day, you may be surprised to see that a positive line has magically appeared.

How do you tell if it’s a faint positive or evaporation line?

When did the line show up? If a pink line showed up quickly, then it is likely a positive, pregnant result. If the line only showed up much later (say ten minutes or more) than the control line, it may be an evaporation line.

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.

What if I accidentally pee on the pregnancy test window?

I peed on the test result window; does it affect the result? It happens! As we stated above, the test window isn’t waterproof, so it’s possible you could get an inaccurate result. Try taking another test (use a cup and dip the test if that’s easier!) to ensure you’re getting accurate results.

What does the second box mean On a Clear Blue pregnancy test?

Negative Pregnancy Test

For two-window tests, the first window would show the test line and the second window would show a single line that looks like a minus (-) symbol. This means you are not pregnant.
