The pregnancy test stick has one very light line and one very dark line. What's going on?

For women whose menstruation is delayed, if they want to know whether their menstruation is delayed due to pregnancy, the easiest way is to use a pregnancy test stick. However, many women will have some problems when using the pregnancy test stick for the first time. For example, some of them have improper operation methods, resulting in inaccurate results. However, the most difficult to explain is the situation where one line of the pregnancy test stick is very light and the other is very dark. So what exactly is going on?

1. What does it mean when the pregnancy test stick shows one dark and one light? If the pregnancy test stick shows one dark and one light, it means it is a weak positive. A weak positive also means that you are pregnant, but it shows a weak positive because it has not been long. It will show a positive after a longer time.

2. How to read the results of pregnancy test sticks

Not pregnant: Only one control line appears, indicating no pregnancy. Pregnancy: If two lines appear, that is, both the control line and the test line are colored, and the test line is obviously clear, it means that you are pregnant; if the control line is obviously clear and the test line is very light, it means that you may be pregnant. Please collect morning urine with a new morning paper and retest every 2 days. Invalid: No control line appears within 5 minutes, indicating that the test is invalid or failed.

3. Precautions when using pregnancy test sticks In order to improve the accuracy of pregnancy test sticks, pay attention to the following points when using pregnancy test sticks: pay attention to the production date on the packaging box, and do not use expired early pregnancy test paper, because chemical agents will become ineffective over time or if stored improperly.

Read the instructions carefully before doing the self-test, and then follow the instructions carefully.

Pregnancy test sticks are generally more accurate when checked 7 days after the period is delayed. Because it is related to HCG in the body, it can only be clearly measured when HCG reaches a certain level, so it is best used 7 days after menstruation is delayed. If the pregnancy has just begun, or there is a possibility of ectopic pregnancy, the HCG level in the body is generally low. The test sample needs to be left to stand for more than 3 minutes (generally only 1 minute is needed), and it is necessary to carefully identify whether there is a weak positive, and the color band in the test area only appears faintly.

4. Choice of pregnancy test time: The pregnancy (positive) result can be read after 1 minute (30 seconds at the fastest), which means that if two lines are clearly shown after 1 minute of testing, it indicates a pregnancy (positive) result, and there is no need to wait for 3 minutes before reading. The result of not being pregnant must be confirmed after 3 minutes. This is because in the early stages of pregnancy, the HCG hormone content in the urine is very low, and a weakly positive result may appear during the test. The weakly positive result may not be displayed after 1 minute. As the reaction time increases, it will take 3 minutes for two lines to appear. At this time, the appearance of two lines should still be interpreted as a pregnancy (positive) result. If there is still only one control line after 3 minutes, it can be judged as a not being pregnant (negative) result.

Now you should have understood what it means when one line is very light and the other is very dark on the pregnancy test stick. For women who have had sex, regardless of whether they have had sex during the ovulation period, if this happens when using a pregnancy test stick, it means that you are pregnant. If you feel that you did not operate it correctly and caused one line to be very light and the other line to be very dark on the pregnancy test stick, you can go to the hospital for a blood test to confirm.
