Short answer
Increasingly, yes. Saliva-based kits do not need cold-chain transport, so they can be shipped to and returned from Tier II and Tier III towns, which historically had no access to genetic testing at all.
Genetic testing used to be a metro-only luxury because blood collection needed temperature-controlled logistics that smaller towns lacked. Saliva kits remove that barrier entirely. This is quietly one of the biggest shifts in Indian healthcare access: the ability to test from a town that has never had a genetics lab anywhere near it.
