This is how you can implement same service while preserving privacy:
1. Customer goes to nearest pharmacy and buys sterile vial and swab.
2. Customer takes sample, writes 30 random numbers on the vial and sends it via mail.
3. Once a month one giant zip file appears on service's website with random numbers and corresponding diagnoses. Customer downloads it and find their random number and corresponding diagnoses.
