Ten days ago, I had running noses, itching throat, and then sporadic coughing, and my daughter told me that I might catch hay fever.  She gave me some pills to take, and my wife made ginger soup for me.  But till now I still coughed, so I suspected if I caught Omicron or something, especially when I read an article from an UDN co-blogger saying she had contracted the virus out of nowhere.

Suddenly I thought why not taking a self-test with the kit of COVID antigen rapid test that Biden administration gave us earlier, free of charge.  So yesterday afternoon I took a swab, a reagent, and a test card out of the kit and followed the instruction to give myself a test step by step.  After fifteen minutes the result came out: Negative.

PS The self-tester must brush the swab in BOTH of his or her  nostrils, not just one nostril that I took in Taiwan last June, which cost me seven thousand TWDs and twenty-four hours to obtain the result, oh my goodness.  BTW, the test kits are made in China.
