Given we don't know the revenue split on Q2 sales (COVID/HIV) I wouldn't want to make a dollar value call. All I would be willing to confirm is that Q1 we sold 100K of RAT + 270K RAT in Q2 (90k per month) = 370K as a minimum for the first few weeks of January. If only we knew the sale price per unit.

If I were to make pure speculation:
I bought a box of 20 @ $299.00 from an online retailer (assume a 50% mark-up for their over head cost and profit margins) that would mean they purchase a box of 20 from AT1 for $199.33 or $9.95 per test. So as a minimum for Jan where 370K units have already been sold, this would equate to revenue of $3,681,500 for RAT sales.
