Named after a touchstone

Our story
Dr. Nusrat's grandfather was a goldsmith in Aminabad. Before he sold anything, he rubbed it on a kasauti, a black touchstone, and read the streak it left. Nothing left his shop untested.
In 2012 she opened a two-room lab in Vibhuti Khand and named it after that stone. Every report is checked and signed by her before it goes out, and the price of every test has been on the wall since the first day.
Home collection started in 2016, when too many patients' parents were struggling to reach the lab fasting at 7 am. Now the prices are online too, the collector comes to your door, and the report arrives on your phone.
