They may not be 100% accurate but this brand of tests showed me that I was positive for Covid after which I went into isolation mode. Stupid me, after going for 2.5 years without even a cold or sore throat I decided to remove my mask at a Chris Rock standup concert and 2 days later I felt a sore throat coming on. I immediately took an iHealth home test and BOOM, two lines showed up. My doctor prescribed medicine that same day and 10 days later I was ok. Being fully vaccinated with boosters was also a key element in only having one bad day. These tests are good to keep around the house just in case. We don’t want to be spreading Covid to anyone, especially family. I learned my lesson.
