I'm going to have to let Arianne answer the swab question if she can. If not, we can circle back.
On the mask question, we're seeing a range of prices for masks, Mr. Chair. When this crisis started, we were looking at about $1.20 a mask for orders early on. For more recent orders, you're seeing prices quoted up to $5 and $6 a mask for N95 respirators, and so the cost of a mask depends on when you placed an order, frankly, and when you had your arrangements in place.
Maybe I'll flip to Arianne to see if she can shed some light on the swabs.
