The mаjоrity оf аrbоviruses, including West Nile Virus (WNV), hаve a short period of replication (short-term and low-level viremia), limiting the utility of molecular tests. As such, serology is commonly used for disease confirmation. You are working on the serology bench and have been asked to provide guidance on a patient with a negative WNV molecular test. The clinician is looking for a 4-fold rise in IgG titer. You review a recently published article providing these data on IgM and IgG antibodies to WNV. What guidance do you provide to identify a 4-fold rise in IgG titer, given the data provided in this table?
