Chapter 93 : Introduction
This is the introductory chapter to the section Human Immunodeficiency Virus(HIV). The laboratory evaluation of patients with HIV infection has evolved from basic flow cytometry to detailed molecular analysis of viral quasispecies and quantitation of tetramer-positive T cells. As the number of HIV infections worldwide continues to increase, the need for laboratory capabilities for the monitoring of these patients has increased as well. This need is even greater given recent advances in treatment strategies that will hopefully turn this disease into a chronic manageable illness. This section deals with the laboratory immunologic and virologic perspectives of HIV. From determining a patient’s relative risk of developing an opportunistic infection to monitoring immunologic responses to candidate vaccines, the clinical immunology lab plays a major role in the area of HIV. This section deals with the laboratory immunologic and virologic perspectives. The chapter provides brief insights into each chapter under this section.
