What Does One Line In C And One Line In T In Pregnancy Tests Indicate?

Hi yesterday i did a pregnancy test (Pregcolor premium) the result was one line in C and no line on T but that was in the 3-5 minutes range, but 2 hours later I saw the test and there was a thin light line on T.. What that means? Is an evaporation line or what?

Hi and welcome to HCM

C means control line and it will be dark line always. You are suppose to compare T line (test line ) with C line.

Two dark or slightly dark line in T indicates pregnancy. Usually the test result is valid if read with in 5 minutes. Any result after 1 hour or 2 hour is invalid even if a line develops in T section

In your case it is negative, dont take readings after 2 hours, which will show false positive sometimes.

If you have missed your periods then wait for one more week and redo the test using early morning urine sample.
