CD+4T淋巴细胞(简称CD4细胞)计数是艾滋病病毒(Human immunodeficiency virus,HIV)感染临床分期、疾病进展监测、机会性感染的风险评估、抗病毒治疗适应证选择及疗效评价的重要实验室指标。室间质评作为CD4细胞检测实验室质量控制的手段之一,是CD4细胞检测结果的准确性及不同实验室间检测结果可比性的重要保证。为提高云南省CD4细胞检测实验室的检测质量,自2005年起,云南省疾
The count of CD + 4T lymphocytes (referred to as CD4 cells) is an important laboratory index for clinical stage, disease progression monitoring, risk assessment of opportunistic infections, selection of indications for antiviral therapy and therapeutic evaluation of HIV infection . As one of the means of quality control in CD4 cell testing laboratories, laboratory quality assessment is an important guarantee for the accuracy of CD4 cell test results and comparability of test results between different laboratories. In order to improve the quality of detection of CD4 cell testing laboratory in Yunnan Province, Yunnan Province has been undergoing illness since 2005
