Step by step
Solved in 2 steps
- Why is a false-positive more significant in HIV testing of patients than in screening donated blood for transfusions?What are the main biomarkers in the blood that can be used to diagnose HIV infection? Give at least one advantage and one disadvantage for each biomarker. What tests are available to detect each of these biomarkers?What are the current prevention guidelines for HIV/AIDSinfection? Are they effective?
