How did they know that the aborted foetus is a normal 46 XY so quickly, if amniocentesis has just been done? I can only assume that karyotyping of amniotic cells has such an ultrafast turnaround time, well done!! Best wishes to All Mohammad "Colley, Michael" <[log in to unmask]> wrote: I have just received the following letter from one of our obstetricians: "I am not sure if you are keeping a record of problems with triple screening. This is to report that Mrs. X. has just had an amniocentesis for a 1:100 screen positive test only then to miscarry a normal infant, 46 XY." I have (perhaps not quite so) gently pointed out to him that 99 people with a 1 in 100 risk will have normal pregnancies, and have asked "where's the problem?" Do our clinical colleagues understand the meaning of any of the tests they're doing? A Happy Christmas to All. Michael Dr. C. M.
