Also known as: TSHORT

Clinical Use

Use

The Lymphocyte Subset Panel 4 test is used for monitoring the immune status of HIV-infected patients and is particularly useful for decision-making regarding the initiation of prophylaxis and antiviral therapy. CD4 T-cell levels, which are measured in this test, serve as important markers for evaluating the progression of HIV and determining treatment efficacy. The test is performed to establish decision points for initiating interventions such as P. jirovecii prophylaxis, antiviral therapy, and monitoring the efficacy of treatments. Regular monitoring, as recommended by the Public Health Service, aids in the longitudinal assessment of HIV-infected patients, helping to inform treatment decisions and improve patient management.
