The medical services company MDS México has launched a rapid covid-19 testing service that uses blockchain technology to verify the results.
According to an October 17 report from the local media outlet iProUP News, MDS Mexico has launched a digital platform that allows its patients to access results that are updated in real time. The results are also physically delivered, with a QR code that can be scanned to verify the results and access a patient's vaccination history on the MDS Mexico blockchain.
MDS stated that it adopted blockchain to safeguard clinical test results, protect patients' personal data, and prevent falsification of covid test results. The MDS website says:
"To avoid falsifying negative results, we began to certify the SARS-CoV-2 detection tests with blockchain technology and cryptographic signature, which protects the information in a unique, immutable and unalterable QR Code that can be verified worldwide" .
Test results uploaded to the MDS blockchain also include a cryptographic signature from the doctor who verified the test result.

MDS is not the first entity in Mexico to adopt blockchain for digitized COVID test results, with the National Chamber of Commerce of Mexico (CANACO) announcing a state-backed initiative to digitize vaccination passports in partnership with private blockchain tech company Xertify in April.
In August, representatives of the blockchain industry in Australia similarly lobbied for the introduction of a blockchain-based vaccine registry to stop the proliferation of counterfeit COVID-19 vaccine passports online.
