I have never bought one before and feel shy asking at the medical shop near my house. Are these kits available in normal pharmacy or online also, pls tell? Which one did you use first time?
Kits are cheap, around 50-100 rs at the medical store. If you want to be fully sure later, doctor can do a blood test but for first check the kit is enough.
Any chemist or medical store has it, no prescription needed. If you dont want to go out, order on a pharmacy app, comes same day in most cities. Takes 2 mins to use.
