I'm really worried because my father-in-law just tested positive for COVID-19. His report says "RESULTS Positive" but there's also something called "Bio Ref Interval" that shows as "Negative." Can you help me understand what that means? Is this related to a stage of COVID-19, or does it indicate something else?

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.

I recently got my HIV test results back, and they came out as non-reactive with a COI of 0.290. I'm a bit confused about what this means. Is it a positive or negative result? Can you help me understand?

I can understand your concern. Why were you advised hiv 1 and 2 test in the first place? Was there any history of risky behaviour recently? The present report which you have posted here is negative. There's nothing to worry regarding it. But if there's any recent history of risky behaviour, then repeat the test after 3 months. Because the test can be negative during window period.

I'm really concerned about my HIV status. So, I had a PCR RNA test 22 days after potential exposure, and it came back not detected. Then, at 44 days, I did an HIV combo test and it was negative. Finally, I did HIV rapid testing at 76 days, and that was negative too. Based on these results, am I in the clear?
