When is the most accurate time to use a pregnancy test stick? What are the precautions when using a pregnancy test rod

Is the pregnancy test stick accurate in the afternoon?

If a woman is really pregnant, she can also use a pregnancy test stick in the afternoon.

Try to use the first urine test in the morning as hormone levels are most easily detected at this time. If it really doesn't work, make sure urine is in the bladder for at least the necessary time. Don't drink too much water to increase urine, as it will dilute hormone levels.

Before starting the test, carefully read the instructions and follow each step accurately. Some medications may affect test results, so it is important to carefully read the label instructions.

In addition, in the case of ectopic pregnancy, the HCG level may be very low and cannot be detected through a pregnancy test rod. If you need to confirm the test results, be sure to see a doctor.

2. What is a pregnancy test stick?

Pregnancy Test Kit testing principle: Pregnancy Test Kit is a product of in vitro diagnosis (IVD), which is the use of a pregnancy test rod to detect human chorionic gonadotropin (HCG) in urine. HCG is a hormone secreted by the placenta of pregnant women, which is distributed throughout the body and acts on target organs. There is also a certain concentration of HCG in urine. At present, most pregnancy testing products on the market use colloidal gold method, and the H in urine is qualitatively or semi quantitatively detected by CG based on the double antibody sandwich principle to determine pregnancy.

3. Explanation of pregnancy test results

The pregnancy test stick is not pregnant: there is only one control line, indicating no pregnancy.

Pregnancy: There are two lines: the control line and the testing line both show color, and the testing line is clearly visible, indicating pregnancy; If the control line is clearly visible and the color of the test line is very light, it indicates possible pregnancy. Please collect morning urine every two days with a new morning paper for retesting.

Invalid: If there is no control line within 5 minutes, it indicates that the experiment is invalid or failed.

When is the most accurate time to use a pregnancy test stick?

The principle of a pregnancy test rod is urine testing, which uses the HCG contained in urine to check for pregnancy. HCG is a hormone secreted by pregnant women, which is present in urine and blood. Generally, pregnancy tests use the combination of single and multiple HCG antibodies in the device with antigens in the urine to determine pregnancy or not. It is commonly known as a pregnancy test rod, pregnancy test tablet, or pregnancy test card.

Usually, menstruation is delayed by 7-10 days, and using a pregnancy test rod is the most accurate because the test rod mainly determines the level of HCG in the urine of women of childbearing age to determine whether they are pregnant. Due to differences in HCG emissions among different women, using a pregnancy test rod too early may lead to inaccurate test results. When menstruation is delayed by 7-10 days, the concentration of HCG in the urine of women is the highest, so the test results are often the most accurate.
