Event Description

False negative result (s).It was really hard to read these.My husband and i were definitely covid positive because we had been exposed to others who tested positive and then we had symptoms.Only one of his tests showed a bright red line.Most of the tests we took showed very very faint pale line or no line at all.We followed the directions exactly.I could see how these could be easily misinterpreted.
