I have been also wondering about this. My impression is that Tamil Nadu is much better in terms of health care compared to many Indian states. So, its strange that the parents are refusing to get tested. I am thinking that the parents are afraid to take public transport, and they don't want to burden their NRI son/daughter, so are making up excuses.

Tamil Nadu, Kerala are significantly ahead in many key social and public health metrics. Were they not been compensated for by BIMARU (roughly, Bihar, MP, Rajasthan, Uttar Pradesh) states India would be competitive with first world standards. Unfortunately, the BIMARU states are the most populous and consequently controls the political fate of the rest of the country.
