How does early pregnancy test paper go from deep to shallow?

1、 Urine sample 1 this reagent uses human urine as the test sample. 2. Collect urine in clean and clean containers. Urine can be detected within one day. It is recommended to use urine in the morning. 3 after taking urine, if it can not be used in time, it should be put in the refrigerator for 6-8 hours.

2、 Methods 1. Use disposable urine cup or clean container to collect urine. 2. Tear along the incision of the aluminum foil bag and take out the test paper for testing. 3. Strip type: immerse the end of the test paper with the arrow mark into the container containing the urine sample to be tested (the urine sample is not allowed to exceed the max line), take it out and lay it flat after about 3 seconds（ Card type: suck 0.2ml (3-4 drops) of urine sample into the sample adding area with a straw. Pen type: pull out the cap, let the urine drench directly in the sample adding area when urinating, and maintain the urine receiving time of 3 seconds (please note: the urine should not exceed the arrow, so as not to wet the test area and affect the test results). 4. Observe the test results of the test area: observe the test results within 5-10 minutes. It was strongly positive within 40 seconds. Positive: the upper and lower ends of the test strip have color bands, indicating pregnancy. Negative: only a purplish red band appears at the upper end of the test strip, but no band appears at the lower end, indicating that she is not pregnant. Invalid: no color band appears. It indicates that the strip is invalid.

3、 Results 1. Negative: there is a purplish red line (control line C) in the test area, indicating that she is not pregnant. 2. Positive: two purplish red lines (control line C and test line T) appear in the test area, indicating pregnancy. The color intensity of detection line in different pregnancy stages changed with the change of hCG concentration. Therefore, the test paper of early pregnancy from deep to shallow should be the concentration problem. 3. Invalid: there is no purple red line in the test area or there is only one purple red line (test line t line) in the test area, indicating that the test fails or the test paper is invalid, so it should be retested.

matters needing attention

If you do a urine test too early, the negative reaction may be wrong. If you do pregnancy self-test at night, the accuracy will be more or less affected. Pay attention to the shelf life and whether the seal is in good condition.
