  • Title: Utilization of follow-up specimens from viremic blood donors to assess the value of west nile virus immunoglobulin G avidity as an indicator of recent infection.
    Author: Prince HE, Lapé-Nixon M, Busch MP, Tobler LH, Foster GA, Stramer SL.
    Journal: Clin Diagn Lab Immunol; 2005 Sep; 12(9):1123-6. PubMed ID: 16148183.
    Abstract:
    The value of West Nile virus immunoglobulin G avidity for distinguishing recent from past infection was investigated using 348 follow-up specimens from 170 viremic blood donors. Low avidity accurately indicated infection within the previous 4 months. However, due to rapid avidity maturation in some individuals, high avidity did not accurately indicate past infection.
