Blue HPT

I've heard several people claim that blue tests are unreliable. Is there any truth to this? What makes pink lines better?

The dye in the blue ones is harder to read. I think positives trend to come up fainter.

Pink-dye tests are less likely to give you an evaporation line that might be mistaken for a positive, particularly when you test early.

Personally, I have never had a problem with blue-dye tests. All three of my pregnancies were confirmed with blue-dye tests only, and I've trusted them to tell me I was not pregnant as well. I would probably still use them if I could find them cheaper than Wondfos, or the Dollar General brand, I use (both of which are pink-dye).

Blue dye tests are the devil...infamous for false positives.
