染色體檢測
染色體可以決定生物個體性別。分為X和Y兩種染色體,壹般情況下,人體內每個細胞內有23對染色體,包括22對常染色體和1對性染色體。其中如人類這樣的哺乳生物,男性的性染色體為XY,女性的性染色體為XX。
血液從母血中成功分離出胎兒細胞預示著只需通過簡單的靜脈血液採取途徑即可獲得胎兒DNA來源。孕婦的血液標本被抽出後,首先經過兩次高速離心處理,將上層的清液移入新的無菌管內,冷凍保存備用。然後應用試劑將上清液中的DNA提取出來,將其染色,放在儀器下觀察。如果看到SRY的條帶意味著是男孩,沒有則表明是女孩,而且伴隨胎兒不斷長大,DNA濃度還會越來越高,並在受孕後7周達到高峰。
這些DNA片段和胎兒性別之間到底有種聯繫,一種被稱為“SRY”的基因只存在於Y染色體上,一旦檢測到它的存在,便意味著胎兒是男性,所以分離出母親血液中的胎兒DNA看看能不能找到SRY基因,性別疑問自然迎刃而解。

Chromosome sex examination
Chromosomes can determine the biological individual sex. Divided into X and Y two chromosomes, one case, the human body within each of the 23 pairs of chromosomes, including 22 pairs of chromosomes and 1 pairs of sex chromosomes. Among mammals such as humans, the sex chromosome of the male is XY, and the sex chromosome of the female is XX.
Blood from the mother's blood successfully separated from the fetal cells indicates that only through a simple vein blood to take a way to get the source of fetal DNA. Maternal blood samples were extracted, first through two times of high speed centrifugal treatment, the upper clear liquid into the new sterile tube, cryopreservation. Then the DNA was extracted from the supernatant by using the reagent. If you see a SRY with a boy, not a girl, and as the fetus grows, the concentration of DNA will become higher and higher, reaching a peak at 7 weeks after conception.
In the end there is a link between these DNA fragments and the sex of the fetus, known as a "SRY" gene exists only in the Y chromosome, once detected its presence, it means that the fetus is male, so isolated fetal DNA in the mother's blood to see if you can find the SRY gene, sex naturally smoothly done or easily solved.

Techniques and advantages of chromosome detection
Authority: Baoren medical has been at the leading level in gene detection above, we cooperate the formal authority of the laboratory have advanced equipment and first-class medical professionals.
Accuracy: the use of international technology advanced medical equipment and noninvasive DNA detection, rapid and accurate without pain, we are committed to cooperation in the laboratory are accurate rate of more than 99.4%.
Professional: only a small amount of blood samples extracted from pregnant women to detect blood samples, you can detect fetal free Y-DNA data.
Convenience: 7 weeks after the blood sampling, testing results as long as 2-3 working days

Condition of chromosome detection
A. pregnancy B ultrasound to confirm the gestational age of 7 weeks or more, and B ultrasound examination of the size of the embryo in 10MM or more.
B. did not have a male child within one year.
C. half a year without major surgery, blood transfusion, organ transplantation, abortion.
D. blood group for the public common blood type, natural pregnancy, non test tube baby.
