Is the Zheng Ji Clinic under the Shenzhen Zhongmen overpass accurate for men and women?

It is forbidden to do this test in the mainland, but now many mainland expectant mothers choose to go to Hong Kong for testing. Hong Kong uses genetic engineering technology to collect maternal blood to judge fetal sex. There is no risk to the fetus and mother. Because of the report of blood DNA laboratory, the reliability of detection is about 99.5%. Gender inference is carried out through chromosomes, especially for baby boys, and the reaction is positive and strong. The baby was examined after 7 weeks, and the identification result was obtained about 1 day. If you still don't understand anything, you can call the mobile phone on my account directly. I hope my answer is helpful to you.
