Hi jalgal and sharky,maybe I should share my experiences with your and other MTB on the OSCAR's test issue.
Im 25 this yr and had my #1 M/C last yr on the Dec. I than conceived my #2 very fast on the FEB again. However, nightmare starts on the 12 weeks, which was the OSCAR's test. I was put to the routine detailed scan and the Professor sonographer told me that, "CONFIRM,CONFIRM its down syndrome.See, your bb's neck skin is so thick,normal babies should be >3, however yours reading is 10.5. he only have a 15 percentage of healthy living as the oscar results ratio shows 1:7(which means in every 7, your bb will be a DS). The best option is to ABORT as both of your are still very young. The other option is to do the CVS at 16 weeks to check the KAROTYPE(the genes) whether to keep or to aborted during then.
The moment I heard what the doctor says, really makes my heart breaks. and thinking that my husband and I are still so young, such problem should not occur. The doc then told us that perhaps, its birth defects, whereby the egg and the sperm did not meet properly. After discussion with my husband, we decided not to keep the bb and do further examinations and did my abortion on May.
2 weeks later after abortion, its the routine check up. when back to the doc again, the doc then told us the bb is a female and KAROTYPE is normal. Immediately, emotions stirred and I burst into tears. I confronted the doc, then why the PROFESSOR sonographer told me that its DS in the end she's NORMAL. The doc says, " I dont know, doesnt mean that her Karotype is normal, doesnt mean she is healthy. The neck skin is so thick!!!"
I was devasted and this had put me to a real nightmare. I went home to search online on the OSCAR test and to my knowledge , there are many ppl who experienced the same thing as me. THe doc told them, the bb's neck skin is thick and perhaps, they might be DS, however, some due to religon, they cannot abort, and they gave birth to a healthy baby eventually.
Therefore, I strongly agree that, this OSCAR test can only provide "Probabilities" but not "diagnosis" whether ur child is DS. I really hate myself for not courageous to go true further tests.
Right now, Im preggy again and in my 6weeks. will go to see a diff gynae tml. hope my experiences will let your understand OSCAR test better.
