Avinashkiranoct, nothing has been proven yet. An article in a China paper has validated nothing. Dennis Lo has been quoted as saying he is conducting his own clinical trials regarding the validity of the Downs Syndrome test. Until the clinical trials are completed, nothing is confirmed. Those misquoting and twisting the China article are to be ignored. I would only invest in this stock what you can afford to lose. The 99% success rate that is being thrown around here as fact, is nothing but shear speculation on the part of those who "Hope" more than "Know." Also, do not login to this Yahoo board expecting to be educated. You will not find anything that resembles intelligent discourse here. Good Luck.
