NEW YORK (360Dx) – In an effort to stem a rise in counterfeit diagnostic tests, precision diagnostics scientists at IBM have developed a method to embed security codes in lateral flow and microfluidic tests.
By integrating optical security codes that are deposited in the diagnostic test's flow pathway with a QR or patterned code on the device package, users of the new method could enable more secure supply chains for tracing and authenticating the tests, the IBM scientists said.
