Positive 2-Tiered Lyme Disease Serology is Uncommon in Asymptomatic Children Living in Endemic Areas of the United States.

Abstract

Knowing the frequency of positive Lyme disease serology in children without signs of infection facilitates test interpretation. Of 315 asymptomatic children from Lyme disease endemic regions, 32 had positive or equivocal C6 enzyme-linked immunoassays, but only 5 had positive IgG or IgM supplemental immunoblots (1.6%; 95% confidence interval: 0.7%-3.7%).
