The visual indicator system mentioned above will show the pregnancy test results. Two important lines or symbols are shown here, the control line (C) and the test line (T). The control line functions to indicate whether the test is functioning properly or not. The appearance of the C line signifies that the test has been carried out properly and the results will be highly accurate.
On the other hand, the T line appears only when there is a sufficient level of HCG hormone present in the urine. The HCG hormone is produced in the body during pregnancy at high levels. If the T line appears on the test strip, then it indicates a positive result. The intensity of the test line does not affect the test results or its accuracy. Even if it appears boldly or faintly, the presence of the T line will confirm that the woman is pregnant.
If the T line doesn’t appear at all after the designated waiting time or more, then it will indicate a negative result. This will suggest that there is no presence of HCG hormone in the urine sample and hence, the woman is not pregnant during the time of testing.
