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.

Hey, I've got a question about the P24 antigen antibody test. If I take it a month after possible exposure, will the results be conclusive for HIV, or should I consider getting another type of test too? I'm anxious to know how accurate it really is at that point.

The P24 antigen-antibody duo test is highly accurate when done after one month of potential exposure, as it detects both the HIV virus and antibodies. However, for a conclusive result, it's recommended to confirm with a follow-up test, such as the HIV RNA PCR test or another antibody test, at 3 months post-exposure.
