What is the role of CD4 in HIV monitoring?
CD4 counts are used to assess the immune status of HIV patients, indicating the level of immunodeficiency.
How does flow cytometry work?
Flow cytometry analyzes the physical and chemical characteristics of cells or particles as they flow in a fluid stream.
What are the benefits of using automated systems in laboratories?
Automated systems increase efficiency and accuracy in sample preparation and analysis.
Why is quality control important in laboratory settings?
Quality control ensures the accuracy and reliability of test results, which is crucial for patient diagnosis and treatment.
How many laboratories are involved in this study?
The study involves 70 laboratories across South Africa implementing the assays.
What is the significance of viral load assays?
Viral load assays measure the amount of HIV in the blood, helping to monitor treatment effectiveness.
