MDS Mexico, the medical services company, will use blockchain technology to verify rapid COVID-19 test results.
It has been reported that MDS Mexico has launched a digital platform allowing its patients to access results that are updated in real-time. Results are delivered physically and feature a QR code that can be scanned to verify the results and access a patient’s vaccination history on MDS Mexico’s blockchain.
However, MDS stated that it adopted blockchain to safeguard the results of clinical tests, protect patients' personal data, and prevent the falsification of COVID-19 test results.
MDS’s website said:
“To avoid the falsification of 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.”
The report said that testing results uploaded to MDS’s blockchain also include a cryptographic signature from the doctor who verified the outcome of the test. MDS is not the first entity in Mexico to embrace blockchain for digitized COVID-19 test results, with Mexico’s National Chamber of Commerce (CANACO) announcing a state-backed initiative to digitize vaccination passports in partnership with private blockchain technology firm Xertify in April.
Thus, in August, blockchain industry representatives in Australia also pushed for the introduction of a blockchain-based vaccine registry to stem the proliferation of counterfeit COVID-19 vaccine passports online.
