When 29-year-old Dheeraj* (name changed), a resident of Alwal in Secunderabad, showed symptoms of COVID-19, he underwent an RT-PCR test at Tenet Diagnostics Centre in Vikrampuri on April 23. While the rate for the COVID-19 test is capped at Rs 500, Dheeraj was charged Rs 1,000. “A diagnostic centre close to my house was charging Rs 500, but they were taking only pre-booked patients. I had to book a slot, which was taking time. So I went to Tenet, without realising that they were charging double the amount,” he said.
