·What is an early pregnancy test?
Early pregnancy test strips, pregnancy test sticks, pregnancy test strips, etc. are collectively referred to as early pregnancy detection reagents. Its function is to determine whether pregnancy is by detecting whether the urine contains a certain amount of human chorionic gonadotropin (HCG). It is the same principle as the urine pregnancy test commonly used in hospitals.

·What are the early pregnancy detection reagents?
At present, the early pregnancy detection products on the market are roughly divided into three categories. Early pregnancy test paper/strip, early pregnancy test pen (pregnancy test stick/pen), gestational week pen. Among them, early pregnancy pens are divided into low-end early pregnancy pens and high-end early pregnancy pens according to their different functions and technologies.

Application place
Early pregnancy test strips/strips are widely used in community hospitals, private clinics, etc. due to their low price and convenient use.

· Frequently asked questions during the use of pregnancy products.

1. The use time of early pregnancy detection reagents
Clinically, 10 to 14 days after the menstrual delay is considered as the appropriate detection time, because the HCG value is significantly increased at this time. However, when tracking the use of pregnancy test products, we found that "women with a relatively stable menstrual cycle and a cycle of 28 to 30 days may detect pregnancy when their menstruation is delayed by 2 to 3 days when using pregnancy test products. Of course, you must know that this time is related to the morning and evening of ovulation and the formation of fertilized eggs. The earlier ovulation, the earliest formation of fertilized eggs. The sooner the urine pregnancy test is positive, the earlier it will appear. Therefore, it is recommended that menstruation be performed in the absence of measures such as intercourse or contraceptive failure. If the cycle is delayed again, please take the self-test 2-3 days after the menstrual period is delayed. If the test is negative, you can re-test after 3-5 days to prevent missed diagnosis.

2. Does the pregnancy test show one deep and one shallow indicate that you are pregnant?
When the pregnancy test stick is dark and light, generally the (C) line in the quality control area is a dark line, and the (T) line is a light line. The color of the (C) line indicates that there is no problem with the product quality and sampling, and the light color of the (T) line is weakly positive, which generally represents early pregnancy. If you want more accurate results, you can re-test after 3 to 5 days or go to the hospital for a blood HCG test to confirm the final result.

3. When is the most accurate pregnancy test?
Usually urine can be detected within a day, but the concentration of HCG is highest in morning urine. At the same time, in order to improve the positive rate of the test, the amount of drinking water should be reduced as much as possible the night before.

4. Are the two red bars necessarily pregnant?
Two red bars appear after the pregnancy test product is detected, which means that the possibility of pregnancy is very high, but not 100%. Uterine fibroids, endometrial hyperplasia, choriocarcinoma, hydatidiform mole or menopausal patients are due to the HCG content in urine. higher, may result in a positive result. Therefore, it is recommended that after a positive result, you can go to the hospital for a color ultrasound test 40 days after the last menstrual period to ensure whether the pregnancy is normal.
