The method of using the early pregnancy stick, or pregnancy test, is as follows: i. Put on 1 time gloves when you wake up early in the morning and use a clean container to take an appropriate amount of urine for the first time in the morning. Place the pregnancy test in a container with urine, taking care not to go beyond the red color of the stick label, and then leave it for 1 minute. 3. Then turn the stick over and turn the observation window upward, and continue to hold the stick diagonally. When you observe a purple liquid crawling across the observation window, a purple line will appear in the observation window within 1 minute. The result of pregnancy can be read after 1 minute, while the result of not pregnant can be determined after 3 minutes, and the result read after 5 minutes is invalid. If a control line appears on the pregnancy test stick, it means no pregnancy; if two lines appear, that is, both the control line and the detection line show color, and the detection line is obviously clear, it means pregnancy; if the control line is obviously clear and the detection line shows light color, it means possible pregnancy, use a new pregnancy test stick and retest with morning urine every 2 days; if no control line appears within 5 minutes, it means the test is invalid or failed.
