The principle of test strips
Test strips test urine to determine pregnancy. After pregnancy occurs, a woman produces a hormone called human chorionic gonadotropin (hCG) in her urine. The test strips contain substances called antibodies that recognize and bind to hCG. When the hCG content in the urine reaches a certain level, the test paper will be stained with a different color, thus determining whether you are pregnant.
Correct usage
The correct use of test strips is crucial. Here are the steps to use it correctly:
1. Choose the test strips that apply to you. On the market, some test strips are relatively sensitive and can detect pregnancy in the early stages of pregnancy, while others need to be detected in the early or late stages of pregnancy.
2. Try to test in the morning. Collect urine for testing from the first urination in the morning because hCG levels are highest at this time.
3. Collect clean urine. Use a clean cup to collect urine and ensure that the test strips are not contaminated or interfered with by other substances.
4. Use test strips correctly. Dip the test strip into the urine, wait a few seconds to a few minutes, and then remove the test strip according to the instructions on the instructions.
Result Judgment
The detected results need to be viewed properly, and there are several aspects that need to be paid attention to:
1. Read the result determination rules in the instruction manual. Different test strips will have different judgment rules, and these rules must be followed to correctly judge the results.
2. Check the test time. Generally, if a dark-colored line is displayed in the control window during the specified test time and another line is displayed in another detection window, the test result is positive.
3. Test multiple times. If you have a negative pregnancy test but still feel like you might be pregnant after having sex, you can retest after a few days or a week to get an accurate result.
Notes
When using test strips to test pregnancy, there are some things you need to pay attention to:
1. Storage of test strips. Test strips can only be used if stored correctly. Test strips should be stored in a clean, dry, and cool place.
2. Readings in the test window on the right. Try tapping the test strip gently so that the urine in the test window is evenly added to the window. Do not stir the test strips in the urine as this may cause false readings.
3. Test the recovery period. hCG levels may be high in the weeks after treatment or a miscarriage. In this case, the result will show a false positive, so it is recommended not to take a test strip pregnancy test during this period.
