Is the pregnancy test accurate in the morning and evening?

For women who are ready to get pregnant, they may be ready to test the way of pregnancy at any time, but in fact, the test results in each time period may be inconsistent. For example, in the morning and evening, someone will ask which time period is more accurate. So, go on, is the pregnancy test accurate in the morning and evening?

Is the pregnancy test accurate in the morning and evening? In fact, the instructions of the pregnancy test stick are generally marked with the words "The pregnancy test stick is suitable for urine samples at any time. If it is early pregnancy, it is best to use morning urine", that is to say, it is recommended that testers use morning urine for testing. In fact, pregnancy test paper can be used at any time, and it is accurate sooner or later.

If you only use a pregnancy test stick at night, the accuracy will be affected more or less because the HCG content in urine at night is not as high as that in urine in the morning. In addition, if some women do not operate properly, there may be big errors. This situation does not mean that the pregnancy test paper at night is inaccurate, only that the accuracy is relatively low compared with morning urine. Therefore, if conditions permit, it is recommended to use morning urine test paper, and it is best to use the middle section. Generally speaking, the most accurate result will be determined by the first urine discharged in the morning.

Is the test paper for men and women accurate during pregnancy? There is no scientific basis for detecting gender through urine. The difference of hormones secreted by male and female fetuses in the mother is extremely subtle, and coupled with the interference of the mother's own hormones, it is impossible to distinguish the sex of the fetus only by the difference of hormone levels in urine. It is a fallacy to identify the sex of the fetus according to chromosomes, but the urine of pregnant women does not contain chromosomes.

The principle of detecting fetal sex by urine test paper is identified by the difference of hormones secreted by the fetus in the mother. Human chorionic gonadotropin (HCG) can be detected in urine by fetal sex test paper. The detection principle of this test paper may be to determine the sex of the fetus by detecting the secretion of androgen (testosterone) contained in HCG. However, due to the subtle differences in hormones secreted by male and female fetuses in the mother, and the interference of the mother's own hormones, it is not enough to judge the sex of the fetus only by the hormones in the urine. However, HCG can only measure whether the baby's development is normal, and it is unreasonable to measure gender through urine. Anyone who has studied high school biology knows that sex determination can only be determined by the sex chromosomes of sperm involved in acrosome reaction in the mother's body. Even if the father's germ cells are examined, the sex of the fetus can not be detected.
