3 body of 21- are asked for integratedly weigh congenital I again model or Down is asked for integratedly, be by chromosome unusual (much a 21 date chromosome) and the disease that cause. 60% little patients are inchoate inside the embryo abort namely, the person that survive has apparent intelligence backward, special facial features, grow development obstacle and much hair are unbalanced.
The account that 3 body of 21- solicit integratedly
3 body of 21- are asked for integratedly is the disease of heredity of a kind of chromosome with the common comparison that Everyman knows, have the following to producing account of its a few tall danger:
1, have familial history pregnant woman
In the family, it is at least in 3 generation lineal and consanguineous in once somebody has appeared 3 body of 21- are asked for integratedly.
2, undesirable pregnant is produced history pregnant woman
2 embryoes or when 3 embryoes, in before there is the baby that has been born to misshape when producing, it is direct even be diagnosed to be 21- 3 body are asked for integratedly or other is unidentified the inchoate abortion of the reason such circumstance.
3, senile lying-in woman
We are more than the age be equal to 35 years old, say to serve as senile lying-in woman.
When if have above,3 kinds of cases appear, the likelihood is the risk that disease of a few transmissibility sends high. If appear this kind of circumstance, perhaps had better go in antenatal in equipment pregnant the special doctor that consults outpatient service to refer a specialized subject hereditarily.
Are 3 aspect of 21- critical is the risk serious?
3 body of 21- ask for an examination integratedly to call Tang to ask for an examination integratedly again, the purpose is to pass the blood of assay pregnant woman to combine week of the age, weight, pregnant, pregnant to produce history etc will judge fetal the dangerous rate that has Tang to be asked for integratedly. 3 aspect of 21- are critical the risk is all to it the differentiate of the risk is to have beforehand appraise value, calculate a value, the level that decides to them commonly is: When the risk the value is more than be equal to 1: 270 when, be called high risk; 1: 270 to 1: 1000 between, be called critical risk. To the pregnant woman of critical risk, darling has the possibility the risk of disease of 3 body transmissibility wants 21- a few taller, the needle suggests below to making at this kind of pregnant woman:
1, do check without the sieve that achieves DNA. It is exsanguinate examination, not be one has achieve an examination, and without achieve DNA the susceptibility that to 21- 3 body ask for integratedly can be achieved 99% the left and right sides, so, still recommend those who make a such inspections quite.
2, make vivid check of nap of amnion antrum puncture. If undesirable pregnant is produced history, undesirable familial history, or the age is more than the senile lying-in woman that is equal to 35 years old, the proposal makes vivid check of nap of amnion antrum puncture.
Generally speaking, have familial history, undesirable production history pregnant woman or senile lying-in woman, relative to character, the high risk possibility that 3 body of child occurrence 21- ask for integratedly will be a few larger.
