There are many scams related to blood tests in China, mainly including illegal identification of fetal gender, false medical tests and fraud. Therefore, the domestic blood test that costs 1,000 yuan to determine the gender is not reliable. Not only is its accuracy not necessarily 100%, but it is also easy to fall into the scam of blood testing to determine the gender.
Although the country currently supports four-dimensional color ultrasound, blood tests, amniotic puncture and other examinations, they cannot be used to detect the gender of the fetus. Unless there are special circumstances, it is generally allowed to identify the gender of the fetus, which is illegal. 
Domestic blood test for 1,000 yuan to check whether male and female is reliable
Of course it is unreliable, because no hospital in the country, whether public or private, will help pregnant women check the gender of the fetus, because the test The gender of the fetus is illegal. The main situations of checking male and female through blood test are:
1. The accuracy of blood test to check male and female
The blood test can be used to check gender 8 weeks after conception, and the accuracy is the highest. Reaching 98%. But what you need to know is that hospitals prohibit non-medical gender identification, and private gender identification is illegal. The blood test can check the gender of the baby, but it cannot check the gender of the fetus in China.
2. Principle of blood test to determine gender
The principle of blood test to determine gender is that during pregnancy, a small amount of fetal DNA will enter the mother\’s blood. As we all know, a person’s gender is determined by X and Y chromosomes, and under normal circumstances, the mother’s chromosomes must be XX. Laboratory technicians can determine the gender of the unborn baby by testing DNA in the mother\’s blood.
3. Blood test to check male and female date
For gender identification, the mother must be at least 8 weeks gestational age or the embryo diameter will be 16.3mm or more. Secondly, the pregnant woman has not given birth to a male fetus within a year. Thirdly, the mother has not had any major surgery, blood transfusion, organ transplantation, miscarriage, etc. in half a year. 
Compare the reliability and safety of blood tests conducted in domestic private institutions and regular hospitals or medical institutions.
Domestic private institutions may be at risk of scams, and it is a wise choice to choose a regular hospital or medical institution for blood testing.
After all, we are all concerned about domestic policies that prohibit fetal gender identification methods, and are concerned about the legal compliance issues with Hong Kong blood tests that are widely circulated on the Internet.
Therefore, attention should be paid to choosing a regular hospital or medical institution for examination.
