There is a faint gray mark on the early pregnancy test paper

Generally speaking, when pregnant women find that their menstrual period is delayed and they are in the pregnancy preparation stage, they will first think of buying pregnancy test strips for self-testing. Due to the convenience and simplicity of the test paper, some women will not understand the results, and sometimes even some strange situations such as gray marks will appear, which will make people more confused.

What is the reason for a faint gray mark on the early pregnancy test paper?

1. Carry out an early pregnancy test. Under normal circumstances, it is possible to show whether you are pregnant in about 10 minutes.

2. If a gray mark appears on the test paper one hour later, indicating a weak positive result, it should not be considered as a sign of pregnancy and should be considered invalid.

How to judge the results of early pregnancy test paper

1. Clarify on-site sampling: the test can be carried out on the day the menstrual period is due, or 7-10 days after intercourse.

2. Test method: Collect urine (preferably the first morning urine), insert a small test strip, and observe the result within 5 minutes.

3. Interpretation of test results: Positive ( ): Dark purple bands appear above and below the test strip, one is located in the test area (T) and the other is located in the quality control area (C). Indicates pregnancy. Negative (-): Only a dark purple band appears on the upper part of the test strip - the quality control area (C) and no color band appears on the lower part - the detection area (T). Indicates not pregnant. Failure: No dark purple bands appear in the quality control area (C), indicating an incorrect operating procedure or that the experimental reagent strip has become moldy and damaged. Note: The printed color of the test strip quality control line and the test connection line may show different shades of color depending on the amount of hCG in the urine. The result judgment is carried out according to the above standards.

Before using the pregnancy test strip, you need to read the instructions carefully and start the test after you have confirmed everything is correct. After the test is completed, relevant standards need to be matched to distinguish the results. If the result is beyond the instructions for use, you need to purchase the test paper again and check again. It is recommended to go to a reliable hospital for a blood test, which will be more accurate.
