Apollo chennai only focus on making money...they dont care about your health...I went to Apollo Chennai two times..never satisfied...just keep in mind...if they are taking too much time ...there is something wrong...remember they have good doctors...but they give more importance to money than your health....there are only two things possible...either they don’t have skilled doctors to cure you in the quickest...or they just want to make money by keeping you involved too long...taking different check ups....I would suggest go for Apollo...only if you are rich....or you don’t have any option left...good luck.
