How to use the early pregnancy test paper

Place 5 drops of fresh centrifuged urine supernatant into the detection hole on the test paper and observe the results with the naked eye within 5 minutes. In general, there are three types of results for early pregnancy test strips: if only a colored band appears in the control area of ​​the test strip (some test strips appear red, some test strips appear blue), it means that there is no pregnancy; conversely, if obvious colored bands appear in both the test area and the control area, it means that the test is positive, indicating pregnancy; if there is no colored band in the control area (regardless of whether there is a colored band in the test area), it means that the test strip is invalid. This test has the advantages of being rapid, convenient, sensitive and highly specific.

Quality Control

Use fresh urine. Specimens that cannot be monitored in time should be stored at 2-8°C and the storage period should not exceed 48 hours. The test strips stored at low temperatures can be opened and used only after returning to room temperature. Pay attention to the validity period of the test strips. The methods of kits produced by different manufacturers vary. The operating requirements of the kit used shall prevail.

It is easy to collect 100ml of the first morning urine (midstream urine), centrifuge it and take the supernatant for examination. If it is proteinuria, it should be heated and boiled for 3 minutes, then centrifuged and the supernatant should be examined. Specimens with severe hematuria, bacteriuria, and proteinuria should not be used. During the testing process, positive and negative controls should be set for each batch of tests.

LH, FSH, TSH, etc. in urine can cross-react with HCG in the test, resulting in a false positive. Methods to avoid false positives: ① Try to use monoclonal antibody two-point enzyme immunoassay to reduce cross-reaction; ② Urine should be collected for testing during the ovulation period or 3 days after ovulation; ③ For patients who have undergone bilateral oophorectomy, intramuscular injection of testosterone propionate can be used to reduce LH, and then urine can be collected for testing.
