What exactly a light line on a pregnancy test means depends on the patient’s test results. If there is only one line on the patient’s pregnancy test stick, and this line is the control line, and the control line is light in color, it proves that the patient’s pregnancy test stick is problematic, and the test result is inaccurate if the quality is not up to the mark, so the patient needs to change to another good quality pregnancy test stick for the test. If the patient’s pregnancy test has two lines, the control line is a normal color, the test line is a shallow one, suggesting that the patient is very likely to conceive, because this result suggests that the urine pregnancy test is weakly positive. The patient needs to be tested again the next day with morning urine, and if it becomes strongly positive, it means that the patient is pregnant. The patient can also confirm the pregnancy by checking the blood chorionic gonadotropin, if the patient’s blood chorionic gonadotropin is more than three times the normal value, it also means that the patient is pregnant.
