If only one coloured line appears on the strip, the test is negative and you are not pregnant. If two coloured lines appear, the test is positive, which means you are pregnant. Even if the lines are light in colour, you may assume you are pregnant. 22 февр. 2019 г. The pregnancy tests kits come with strips that have specific dye in them. Once the urine sample is placed, a chemical reaction produces either pink or blue lines to indicate a positive pregnancy test along with the control line used as a reference. Even though they come in different colors, they work on the same mechanism and are effective.
How do you know if it’s a positive pregnancy test?
Positive Pregnancy Test
For single window tests a positive result would show both the test line and another line to indicate that you are pregnant. For the two-window tests, in one window a test line would appear and in the second window a plus sign (+) will appear even if it is faint to indicate that you are pregnant.
Why is my positive pregnancy test line so light?
The strength of the positive test line depends on how much hCG is in your urine. If the line is faint, it usually means that the hCG level is low. One reason why hCG levels may be low could be because you’re still very early into your pregnancy.
What does a positive pregnancy test look like?
A positive pregnancy test result should be pink (or blue) just like the control line. It should also run from the top of the test window to the bottom and have the same thickness as the control line. Essentially, the test line should look like the control line, but it does not need to be as dark.
