Version 2.0 has completely revised HIV frequency sets using the latest Photoanalysis scanning techniques. There are six active strains commonly seen.
The latest scanning technology shows that low-level asymptomatic HIV infections are widespread in the population. They lower immune response and make other infections more common and difficult to eliminate. A researcher noticed that the Hunter 4025 often identifies HIV as a lower level infection that supports primary infections and the HIV frequency sets have been expanded to cover these cases.
