Ann: Cellmid's Shipment of SARS-CoV-2 Tests Received, page-283

Think that 12000 tests means 12000 tests.
Thats what was stated and i dont have any reason to doubt it.
Whether there are more coming and it is only a first availabilty shipment of the first order remains to be clarified.
If it is just a tester to see how things go then if it all turns to custard then there is really not a lot lost from this venture.
I take great heart from the fact that all these others have come on board as I would assume that a lot of people who know what they are doing are in fact endorsing the rationale behind antibody testing and can see a bit beyond a few jumps and bumps on the stock ticker.
