1:50 Risk for Trisomy 21

Hi
I am 20 w pregnant  gynaec here did the Ultasound Level II on 22.7/11 and the report was ok , she sent my blood sample for Triple Marker
MEASURED SERUM VALUES
PARAMETER                            VALUE                        cORR. MoMs
  AFP                                         26 IU/ML                           0.52
  HCG                                        17739.74 ML/U/ML            1.29
  uE3                                         0.82  NG/ML                      0.39
GESTATION AGE                   19+5
Trisomy 21 screening: The calculated risk for TRISOMY 21 is above the cut off which represents an increased risk. After the result of TRISOMY 21   it is expected that among 50 pregnancies with the same data there is one TRISOMY 21  pregnancy. The uE3 level is low. and they have advised for USG correlation.

After this she sent me for sonography at a scanning center for level II scan and Foetal welll being. The report is again absolutely Normal and not even a single marker for Trisomy 21 was seen. the sonographer said the risk  can only be beacuse of the age and had he found evn a single marker he would have recommended Amniocentasis but acc to him it is a normal ongoing preg of 20.1w. Now my question is Should I go Amniocentasis or not. I am totally confused. Please help and guide.

If an amniocentesis makes you feel better, then you should do it. If it doesn't change the out come and you are okay not having it then don't do it, at this point it's going to be what ever you feel you want to do. Sorry you gotta go through this. Hope the rest of your pregnancy is uneventful!

i'm no expert but i've heard that the blood tests are frequently inaccurate and can cause more stress and worry than necessary. i have also heard of people who did all of the tests and it came back positive for down's, etc., and that when their child was born it was perfectly healthy. it is for this reason that i am not going to have genetic screening.

i'm also sorry that you are going through this worry, but i would look at the stats on accuracy for the tests themselves.

it also seems reassuring that your ultrasounds came back normal.
