Diagnosis of HIV/AIDS
- Rapid testing through a saliva test. Results can be ready within a half hour.
- ELISA or Western blot tests—blood tests to determine if the immune system has recognized the HIV virus
- HIV RNA assay—to detect the HIV virus itself
- A type of white blood cell called helper T cells drop below 200 cells per cubic millimeter of blood.
