one more question about evap lines?

Question

what do they look like? are there any color to them? are there one or two? these preg tests are drivin me mad! lol

Answer 1

:)
Stop looking at old tests!!! Look at the time limit that the instructions give you. Once that time is over, wrap up the test and bury it in the trash can and leave it alone. I know it's hard ;)

The best thing that I ever did was to buy a digital test. That way, the lines mean absolutely nothing. The EPT digital test was my hero! You wait a few seconds and find out you are either "Pregnant" or "Not Pregnant." No evap line to worry about. No imaginary line to create in my head.

Answer 2

What's an evaporation line? Evaporation ("evap") lines result with the test's antibody strip just looks slightly different than the space around it. There is a line of antibodies (usually made from mouse cells) in the Control and Test section. The Control line binds with any liquid and turns pink (or blue, in tests using blue dye.) The Test/Result line turns pink only if pregnancy hormone is detected. If not, the moisture passes over this strip and does not turn pink. It may, however, become more visible when the light hits the moisture on the strip-- it may appear gray, colorless, like a "dent" in the test, or like a "ghost line." It may appear at any time-- as soon as the urine hits it, after a few minutes as the test absorbs the moisture, or after the 10-minute time limit. It may appear when the test is drying, or after it has dried. It may disappear as the test is drying, or after the test has dried, or not disappear at all.

The simple fact is that there is always "something there" that is slightly visible-- it's simply the antibodies on the test that would turn pink in the presence of hCG. When the test becomes wet, or as it dries, or after it dries, the antibody strip may become more visible. Therefore, all tests may have them. It is not a defect; it's just how tests are made.

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.

They say to disregard the test results after ten minutes. In my expierence with my friends when we were sixteen, seventeen, etc... I have NEVER seen a negative turn positive. Peeonastick.com has pictures of tests that turned positive after a couple days, it also talks about evaporation lines. I did the same thing she did. I took three clear blue easy tests to see if what happened to her was common. Mine came out positive and my friend who thought she may be pregnant came out negative. A couple days later they are still negative and mine is still positive. The best thing to do is call you dr. tell him/her you have a postive home pregnancy test and I'm sure they will order a blood test for you. Take care!<3

Answer 4

They are more greyish than the color they are suppose to be. Just make sure to check the test in time then you'll be fine♥
