Hi, Does increased Covid antibodies count indicate reinfection? I was Covid positive during the first wave (August 2020). I did my IGG antibodies test in November 2020 and results was 4.33 which was obvious. Five weeks ago my family members (my wife, 5 year old daughter and father in law who was visiting us) and I had cough and cold. My daughter had fever for a day and my father in law was down with it for 3 days. All of us recovered after taking antibiotics. Just out of curiosity I again did my antibodies test and result showed increased count of 22. Both the times test was done using same method (Serum,CMIA). My CRP too was little elevated (CRP: 6.09). Does this mean I was exposed to Covid once again?
