Thank you for the question. I am going to have to respond to this one in English. It's a little technical for me.
Reagent is a chemical necessary for the traditional testing. The main source has been from one company in the past, and there's a global shortage, as the member mentioned, Mr. Chair, so we are now using companies in Canada to manufacture reagent to fill the gap, and that comes with its own challenges. There is a certain kind of chemical called guanidine, which is a little challenging to procure, but we have some already and we're buying more, so we are well on our way to making reagent in Canada to fill in the gap because of the global shortage.
