Thank you for your question. My name is***** and I will do my best to provide a useful input.
What was the lab cut off for a positive result - more than 1.0?
Thank you for the report. You have no reason to worry - the exact antibody values can vary anywhere between 0 and 0.9 - there are competing antibodies and if you have the flu for example your values can change slightly. The results may be higher or lower than your previous report. This is of no significance as long as the report stays below 0.9.
