[External evaluation of the quality of CD4 T cells enumeration in the laboratory of immunology and hematology at the Cocody University Hospital Center].

Introduction: The rate of T lymphocytes-CD4 (TLR4) is a crucial parameter for therapeutic decision and follow-up in patients with Human Immunodeficiency Virus (HIV) infection. This must be determined in a reliable and accurate way. The laboratory of immunology and hematology at the Cocody University Hospital Center has participated in the External Quality Assessment program (EQAP) for TLR4 enumeration provided by QASI (Quality Assessment and Standardization for Immunological Measures Relevant to HIV/AIDS) in order to deliver quality results.
