Positive ( ): Two dark purple bands appear. One is located in the testing area (T) and the other is located in the quality control area (C). Indicates pregnancy.

Negative (-): Only a dark purple band appears in the quality control area (C), and no dark purple band appears in 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.

Common problems with using test strips

1. It is more accurate to test the first urine in the morning, because if you are already pregnant, the HCG level in the morning urine is the highest;

2. The urine used for testing should be close to room temperature. This does not mean that old urine can be used. Therefore, the urine should be tested within ten minutes after being obtained.

3. Pay attention to the production time of the early pregnancy test paper. Although the shelf life of the early pregnancy test paper is more than one year, due to the influence of the storage method, the early pregnancy test paper may become invalid before the expiration date. Therefore, try to use the early pregnancy test paper within one year to ensure reasonable results;

4. Drink less water the day before the test, so that the urine concentration can be higher the next morning. If you are already pregnant, the HCG content will be higher, and the test will be more accurate.

If a woman uses the pregnancy test strip correctly and the pregnancy test strip is not expired or moldy, the test results are generally more accurate. In addition, if you want a more accurate result, you should be careful not to drink too much water the day before the test and use the first urine of the morning for the test.
