Through the second-generation high-throughput sequencing technology, it is possible to determine whether the suspected father and the fetus in the pregnant mother's womb have a biological parent-child relationship, and can directly contact the headquarters consultant to provide one-on-one consulting services. Fetal non-invasive DNA paternity testing mainly depends on the standards of testing institutions, and the report of BGI parent-child relationship testing must be full of more than 500 valid loci, which is why the non-paternal exclusion rate has reached out. Because the number of loci and the amount of related data will affect the accuracy of the judgment results, the report cannot be issued if the detection and judgment standards cannot be reached so high.
During pregnancy, non-invasive paternity testing was carried out by taking 10ml of venous blood from pregnant women, 2-5ml of venous blood from suspected fathers, or various DNA samples such as nails and hair. 【BGI Non-invasive Parent-Child Testing during Pregnancy】Ultra-high detection standard, detecting 16500+ gene loci (detection loci...

The following initial symptoms of pregnant boys are for the reference of expectant mothers, and are not used as an absolute basis for measuring pregnant boys: Initial symptoms of pregnant boys 1. Observe the changes in the appearance of pregnant women: If the pregnant woman's appearance becomes beautiful and smooth, she may be pregnant with a girl; On the contrary, if the appearance becomes ugly, the face becomes rough, and even the face is covered with pimples and other symptoms, it may be pregnant with a boy, which is a more common symptom of pregnant boys and girls.
Early symptoms of pregnancy boys 2: They like to eat salty or sour foods, and they also like to eat high-protein foods such as meat and cheese; The male hormone secreted by the male fetal pill sends a signal to the mother that "must eat", which greatly increases the mother's appetite. In addition, although mothers who are pregnant with male babies give birth to heavier babies, they do not gain more weight during pregnancy than pregnant women who are pregnant with female babies, indicating that the sex of the fetus does not matter.

I want to know how to prepare for pregnancy with a boy.
There are some people who blindly follow some posts on the Internet to regulate alkalinity, and have been focusing on regulating alkaline, all kinds of abstinence from meat, vegetarianism, and even rinsing soda, drinking Su Yingju burning water, etc., which is very wrong. Preparing for pregnancy for a boy mainly depends on the quality of the man's jingzi.
If you want to conceive a boy and have a son, first of all, you should adjust the quality of the man's jingzi, not blind conditioning, go to the hospital to do a routine jingye analysis before conditioning, according to different people's different physique targeted conditioning, blind conditioning is counterproductive. After officially starting to prepare for pregnancy, how can both men and women start to adjust in the general direction?
First of all. Both men and women have a regular schedule and rest, don't stay up late, don't take drugs indiscriminately, don't eat takeaway junk food, eat more nuts, fruits, vegetables, meat, eggs and milk, exercise moderately, and maintain a good mood.
Then, the man regularly goes to the hospital to do routine jingye analysis, and if the data is unqualified, he will continue to be conditioned, don't be afraid of trouble, and continue to adjust until the quality is qualified. Why is this requirement more stringent, because the quality of men's jingzi directly determines the sex of the fetus, maybe many people don't believe it, according to our years of experience in guiding many mothers to conceive sons as they wish, the data on the man's jingzi list is very important, and the poor data rarely conceive a son, but those who insist on conditioning, and those who are qualified in the data are basically pregnant with sons.
And then. Women regulate qi and blood, women are full of qi and blood, secrete more alkaline mucus during ovulation, this is a natural environment for y, very conducive to y to the combination of y and eggs, just mentioned the ovulation period, preparing for pregnancy boys, especially for boys, we are very strict about this ovulation time, in the ovulation time period, cervical mucus is thin, very conducive to the combination of y and eggs, miss this time, cervical mucus becomes thick, acidic, but hinders y y forward, All of us are a little more rigorous about this time card, but also to let everyone get their wish.
Finally, let's talk about some details, that is, many people will make a mistake, that is, the problem of regulating alkalinity, many people think that conditioning alkalinity can make acidic physique alkaline, which is very wrong, some people really quit meat, drink soda and the like. It's really not necessary, but it will lead to bad qi and blood, bad qi and blood, and poor follicle development, which makes it more difficult to conceive. Don't deliberately regulate alkalinity, regulate qi and blood, ovulation time, cervical mucus is naturally alkaline, which is also the magic of nature's evolution.
Therefore, everyone should prepare for pregnancy scientifically and take care of their bodies.
