White vinegar makes pregnancy test stick show pregnancy

Some friends have heard that white vinegar can make the pregnancy test stick show the result of pregnancy. In fact, this statement is incorrect, because the pregnancy test stick detects human chorionic gonadotropin in urine, and white vinegar does not contain such a substance, so it will not show pregnancy. Friends, when using pregnancy test sticks, you should use them correctly according to the instructions.

Principle of pregnancy test stick: Pregnancy test stick is a kind of in vitro diagnostic product. The so-called test is to use the pregnancy test stick to detect human chorionic gonadotropin n (HCG) in urine. HCG is a troponin secreted by the placenta of pregnant women. It is distributed throughout the body with the blood, thereby acting on target organs. A certain concentration of HCG is also present in the urine. Currently, most pregnancy test products on the market use the colloidal gold method, which conducts qualitative or semi-quantitative detection of HCG in urine based on the double antibody sandwich principle to determine whether a woman is pregnant. It is worth noting that such pregnancy test products are not 100% accurate, and certain diseases may also cause increased HCG concentrations in the body, resulting in false positive results.

If two control lines appear after the pregnancy test stick test, that is, both the control line and the test line are colored, and the test line is obviously clear, it means that you are pregnant; if the control line is obviously clear and the test line is very light in color, it means that you may be pregnant, and you need to collect morning urine with a new pregnancy test stick after 2 days to retest; if only one control line appears, it means you are not pregnant. If no control line appears within 5 minutes, it means the test is invalid or failed. At this time, you need to test again with a pregnancy test stick. From the testing principle of the pregnancy test stick, we can know that white vinegar will not make two lines appear on the pregnancy test stick. However, if the pregnancy test stick is not used correctly, it is possible to misread it. When you are in doubt about the test results, it is best to test it several times or go to the hospital for a blood test to test whether you are pregnant.

When should I use the pregnancy test stick?

Pregnancy test sticks are commonly used tools for early detection of pregnancy. The principle is to determine whether pregnancy is achieved by checking the HCG content in urine. HCG is the abbreviation of human chorionic gonadotropin. Five to ten days after successful implantation, the HCG content in human urine will increase. If you use a pregnancy test stick with guaranteed quality and follow the correct method, the accuracy rate of pregnancy testing is over 80%.

1. Because urine begins to produce HCG five to ten days after implantation, and implantation occurs one to two days after female ovulation, it is best to test it one month into pregnancy or 7-10 days after menopause for relative accuracy. Generally, HCG will appear in the urine a few days after the fertilized egg and sperm combine, and it must reach a certain ratio to be detected. It also depends on the method of use. If it is used improperly, there will be errors.

2. Try to use the first urine in the morning for testing, because the hormone level at this time is easiest to detect. If this is not possible, make sure the urine is in the bladder for at least four hours before testing.

3. Do not drink too much water to increase urine, as this will dilute hormone levels.

4. Read the instructions carefully before starting the test and follow each step accurately.

5. Some medications may affect the test results, so be sure to read the label instructions carefully.

6. In addition, if it is an ectopic pregnancy, the HCG level may be very low and therefore cannot be detected by a pregnancy test stick. To confirm the test results, be sure to see a doctor.

Pregnancy test sticks can only be used as a reference. If you want to finally confirm whether you are pregnant, you have to go to the hospital for professional examination to confirm it. Moreover, if a woman has an ectopic pregnancy, it cannot be detected by a pregnancy test stick.
