Yesterday I conducted my first self-test of five requested during guarantine period at home.  The procedures taken, the swab and the reagent as well, are the same as the one I took two months ago in America. (https://classic-blog.udn.com/kkuo0810/171721548).

Because the self-test kits that Biden administration provided are made in China, I just wonder if the one I used here in Taiwan is also a product originally from China Mainland.
