Hi doctor, my father-in-law tested positive for COVID today. His report says "Results - Positive" and "Bio Ref Interval - Negative." I'm not sure what "Bio Ref Interval - Negative" means. Also, is there any specific stage of COVID that we should be aware of?
The "Bio Ref Interval" being negative typically indicates that the test result falls outside the reference range for a negative result, confirming the presence of the virus. As for COVID-19, it doesn't have specific "stages," but the severity can vary from mild to severe, and it is categorized based on symptoms and clinical findings, such as mild, moderate, severe, and critical. It's important to monitor his symptoms and follow healthcare advice for appropriate management.
