Don't worry,your sister will be better. During hospitalisation management of vital of body would be easier. But one thing must be remember that there is not any Medicine except giloy juice which can increase platelet count in just 36 -48 hours.so start giloy juice three time in a day immediately. Some time doctor does not consider or allow to give giloy patient in hospital. So if you want to give it you have to opt way on your risk. But I can ensure you will get better result in 2 days.
