Diagnostic Tests for Assessing HIV/AIDS Severity
CD4 Cell Count Test
The CD4 cell count test is a vital diagnostic method for assessing the severity of HIV/AIDS by measuring immune system health.
Diagnostic Tests for Assessing HIV/AIDS Severity
CD4 Cell Count Test
The CD4 cell count test is a crucial diagnostic tool used to assess the immune system status of individuals with HIV/AIDS. CD4 cells, also known as T-helper cells, play a key role in maintaining immune function. Measuring their levels helps healthcare providers determine the progression of HIV infection and decide on appropriate treatment strategies.
What is a CD4 Cell Count Test?
The CD4 cell count test measures the number of CD4 cells present in a microliter of blood. A lower CD4 count indicates a weakened immune system and a higher risk of opportunistic infections.
Importance of CD4 Cell Count Test
- Helps determine the stage of HIV infection
- Aids in treatment decisions and monitoring disease progression
- Predicts the risk of opportunistic infections
Procedure
A blood sample is collected from the patient and analyzed in a laboratory using flow cytometry technology to count CD4 cells accurately.
Interpreting Results
CD4 cell count levels are classified as follows:
- Above 500 cells/mm³: Normal immune function
- 200-499 cells/mm³: Moderate immune suppression
- Below 200 cells/mm³: Severe immune suppression, risk of AIDS-related complications
Conclusion
The CD4 cell count test remains an essential tool for managing HIV/AIDS and ensuring timely interventions to improve patient outcomes.
