RESUMEN
OBJECTIVE To explore the risk factors and control strategies of nosocomial infection in clinical immunology laboratory.METHODS The positive detection rates of HBV marker and antibodies to HAV,HCV,HEV,HIV,TP,and TB in total of 91 877 samples in clinical immunology laboratory during Jul 2004 and Jul 2005 were retrospectively surveyed and statistically analyzed.RESULTS The number of positive specimens of HBV marker and antibodies to HAV,HCV,HEV,HIV,TP,and TB were respectively 8 376,7,26,24,107,3,522,and 52 and the positive detection rates of these items were respectively 16.68%,0.43%,0.20%,2.22%,6.49%,0.03%,4.75%,and 4.61%.CONCLUSIONS It is very important to understand the infection sources and risk factors in clinical immunology laboratory in order to strengthen management of hospital infection and protection of occupational exposure.
