Are my results false negatives?
Hi, 3 weeks after possible exposure I started experiencing swollen lymph nodes, sore throat, oral ulcer, fungal infection on my skin, flu-like symptoms, and fatigue. I used biosure on days 31, 44, 60, 71, and day 84. All 5 biosures were negatives and now my tongue is still white and there are lesions on my tongue. Since I used 5 biosures and all were negative is there a chance of getting false negatives? should I worry about my results? And is there still a need for me to perform another test?
