You guys are missing the point.

The slides that Dr Malan leaked are for a next-generation quantitative QD antibody test. The other tests on Medek with EUAs are current generation tests. Qualitative, use gold nanoparticles not QDs, simple LFDs, visually read. I don't believe Medek is actually offering QDTK for sale at this time, just their other licensed tests.

The QDTK test uses a cassette (like a LFD) but the cassette is read by a portable fluorescent immunoassay analyzer. Point of care testing. This is not going to be a cheap at home test.

To me the analyzer is existing technology that is already used for other diseases, and probably patented by others.

I think the QDTK test presented in the slides is based on adapting the test cassette to detect covid-19 antibodies with QMC supplied QDs and the read with a third party analyzer. Pasaca could be shopping for the rights to an existing analyzer/company, so I hope Dr Malan didn't let the cat out of the bag too soon. Maybe QMC's "better" QDs will give them an edge over others.

My point was that Dr Malan's post, leaked slides (not formal announcement), and the Pasaca deal integration milestone implies to me that they are still working on development and QDTK is not ready for distribution for Covid or other diseases at this point.

I don't think QMC, Innova or Malan built this from the ground up, just adapting pieces of it as their own.
