The women's body has also sought an appointment with Home Minister Rajnath Singh in this regard.
The Commission had instituted an inquiry into the gangrape and one of its members had visited the town as part of a fact- finding mission.
"In the report we have mentioned that doctors in Bihar still continue to use the two finger test, which has already been banned. We have also sought details from the doctor who carries out medical tests on rape survivors because we suspect that several rape cases are simply brushed aside.
The incident had took place nearly a week ago. Five men who had stormed into the woman's hut, dragged her out and gangraped her in front of her parents and neighbours. The accused had allegedly inserted a pistol and a wooden stick in her private parts.
