Domshak puttar, most strips have two corners marked 'C' and 'T' on the test card. 'C' indicates control. This line must always appear because this is the comparison line. 'T' indicates the test sample. If only one pink/purple lines appear, in the region marked 'C', it means that the test is negative for pregnancy. If two pink/purple line appears, one in the region marked 'C' and the other in the region marked 'T', it means that the test is positive for pregnancy. In case no lines appear, then the test is invalid. Repeat the test with a new kit after 72 hours. If the line formed in region 'T' is faint, this could be due to low levels of hCG hormone. If you get a faint line, repeat the test with a new kit after 72 hours.
