Although the probability cannot guarantee 100% success, it is indeed a very effective test method. Many expectant mothers find two bars on the urine test. The first reaction is pregnancy. Then some physical examinations during pregnancy need to be clearly understood.

▉Popular Science: What is a urine pregnancy test?

Urine pregnancy test, also known as early pregnancy test, determines whether pregnancy occurs by detecting whether the urine contains a certain amount of human chorionic gonadotropin. Normal non-pregnant women test negative, while pregnant women test positive. Generally, a urine pregnancy test will be positive 35 days after menstruation.

Urine hCG is a common laboratory test in obstetrics and gynecology and a common screening method for pregnancy and gynecological tumors. It is generally recommended to use morning urine for hCG testing, that is, the first urine sample after getting up in the morning, because it stays in the body for a long time, the substances are relatively concentrated, and the positive detection rate is high. However, in clinical practice, especially for outpatients and emergency patients, random urine tests are mostly performed.

Why do test strips deceive people?

●The pregnancy is still in the early stages and the hormone levels in the pregnant woman’s urine are still at very low levels and cannot be detected;

● Pregnant women drink too much water, which dilutes the concentration of human chorionic gonadotropin in urine;

●There is a problem with the quality of the test paper. Therefore, in clinical practice, β-hCG is measured in the blood for quantification, because blood is more accurate and sensitive than urine, and it can usually be detected eight or nine days after fertilization.

●In addition, although random urine collection is convenient, it is easily affected by factors such as diet, exercise, body position, time, and medication, and it is often easy to miss substances and formed elements with low concentrations or pathological critical concentrations.

How to improve the accuracy of early pregnancy tests?

1. Pay attention to the production date on the packaging box. Do not use expired test cards or test strips that have been damp.

2. Before using a pregnancy test stick or test paper, read the instructions carefully and strictly follow the correct procedures to increase the success rate.

3. If the self-test result is negative and menstruation still does not come after 1 week, you should do the self-test again. If you are not sure about the test results, it is best to go to the hospital for examination and complete the test under the guidance of a doctor.
