I'm 20 and I play basketball regularly, but I've been having some issues with my knee. Every time I fold my leg, there's this bubble popping sound in the knee joint, and it's pretty painful. Also, my knees are feeling really weak. What can I do to help with the pain and make my knees stronger?

HIV Test Results After Exposure

Your Test Results

1. PCR qualitative HIV test (Day 13): Negative
2. Duo Combo HIV test (Day 14): Negative
3. Duo HIV test (Day 23): Negative

Interpretation of Results

1. High accuracy: Your test results, especially the PCR qualitative HIV test, have high accuracy.
2. Low risk of false negatives: The combination of negative results from different tests reduces the risk of false negatives.
3. Window period: You've tested negative within the window period (23 days), which reduces the likelihood of HIV infection.

Assurance Before 28-Day Confirmatory Test

1. High confidence: Your negative test results provide high confidence that you may not be infected with HIV.
2. 28-day confirmatory test: However, it's essential to complete the 28-day confirmatory test to confirm your HIV status.

Next Steps

1. Complete the 28-day test: Schedule the confirmatory test on or after the 28th day.
2. Maintain precautions: Continue to practice safe sex and maintain precautions until you receive your confirmatory test results.
