The US FDA has authorised the sale and use of a prescription based home test (nasal swab), self administered, results within 30 minutes. It can be used by anyone over 14 years of age, younger children must have the swab taken by a trained professional.
“The Lucira COVID-19 All-In-One Test Kit is a molecular (real-time loop mediated amplification reaction) single use test that is intended to detect the novel coronavirus SARS-CoV-2 that causes COVID-19.”
I wonder, why such products are introduced in countries in the far-east and not in India (yet)?
I guess costs and scale could be the reasons. 
East Asian countries are usually smaller and have reasonably better per capita!
If cost is the reason, then they should definitely introduce this home test kit!
If we take the parent country (of this product) the USA, it had a population of 32.82Crores in 2018 (United States Census Bureau, Eurostat, World Bank) and India (a country in the east) has a population of 135.26Crores in 2018 (World Bank, United States Census Bureau). A difference of 100crores in the population.
Where will more people buy the product?
Where is there a stringent need?
Most importantly, if they reduce the cost of the kit (slightly), more people will buy it in India 
Isn’t this economically (to both producer as well as consumer) benefitting?
And @karnamdpdurga isn’t better capita good for them!
The Health Secretary has clarified today that if a vaccine is introduced in India, it will be disseminated selectively, with priority to the most at health risk.
At that point, a test that works far more definitively than RT/PCR is going to be needed.
But with any luck, we won’t actually have a risky partially tested vaccine thrust down our gullets anytime soon.
