Positive OR Evap after the time limit?


Just wondering if anyone has ever had a faint second line appear on a hpt after the time limit, and what the result ended up being. I'm having this exact problem and each day the line gets a tiny bit darker but is still rather colourless and doesn't appear until AT LEAST 10 minutes later, usually more. From there it remains on the test. I'm so confused!!!

I think colorless=evap. At least that is what someone else posted to me when I put up a photo. I felt like my colorless evap was more pronounced this morning, but I think I am just getting my hopes up.

Try to test again--maybe wait 2 days or something so you will really see a difference in the lines, ykwim?

If it's showing up after the time limit, it's just an evap. The accurate results show within the 1-3 minute time limit, after that test can't be used for an accurate reading. The following link may help explain this a bit better:

http://www.peeonastick.com/hptfaq.html#7

A real positive is identified by its color (pink or blue, whatever the color of the test's dye is) and its appearance within 10 minutes of urinating on the stick. A line that appears after 10 minutes, regardless of color, must be considered an evap line and is caused by the test's chemicals changing. HPT's are rapid assay diagnostics, which means any results appearing after the "rapid" time limit of 10 minutes are invalid.

If you got a faint positive earlier, I would just wait a few days and test again. It could just be that there exists a minimal amount of hCG in your urine.

Thanks for the link!
So does that mean that every brand of hpt has a maximum 10 minute time limit for results?

My FRER just got a nasty evap line several hours after I used it (stupid me should have just thrown it out!!). Based on my numbers, 6 out 7 hpts have evap lines on them, isn't that a bit much?? Maybe I'm just super unlucky. Of course I like to think this means I'm well on my way to a but I know I can't read into it until I get an obvious line WITHIN the time limit!! Anyone else getting second lines on almost every single test but after the limit??

Oddly enough I have an example of the contrary. I fully support to go ONLY by the directions on the box. However, I took a dollar tree test on Wednesday that came up negative. Later I went and looked and it had popped the FAINTEST pink line and then next to it was the evap. I laughed and tossed it back in the drawer and grumbled something about stupid mind tricks. Then Friday I took an equaline test and got a solid BFP. Then next day positive FRER. Apparently, that stupd dollar tree test was telling the truth! I am not condoning my clearly bad behavior! But occasionally these tests do weirdo things!

Not every brand has the same, I don't think. Whatever time limit it gives on the box is the time limit you should go by. Interestingly enough, I've never peed on an HPT before, haha. So, I may have to stop by the Dollar Tree this week!

Oooh, so there could be hope!! I'm so happy to read this even though I feel like I'm grasping at straws. All my recent dollar store tests have produced a faint second line but never within the 1-3 minutes. So frustrating!!
