COVID Test Type

What is the type of test you need for COVID? What other things do you need on the test result paper? Do you need the hospital stamping and QR code?
We went to Vijaya Medical Center in Vizag/Visakhapatnam. There they told us we needed to collect the results in-person because of some hospital stamping. We will be traveling to Hyderabad before the test results arrive. Can someone else scan the result and send it? Can we print the scanned result and use it for travel?
