We consulted a hospital in Hyderabad where the nipt is done. The report came as negative. The sample was send to likhitha diagnostics by th hospital and the report was given by them. When i visited another doctor for second opinion. She is mentioning that she did not heard of it and asking to go for amnio. Doctors i am not sure what to do. My wife is 17 week pregnant now and can any one please suggest if it's an authorised lab and what to do next.
