To assist in correlating data between two national labs, I offer the following results.
here are quest and Labcorp HHV-6 IgG AB results for comparison between the two labs taken on the same person (though two weeks apart, no treatment in between)
1:20 Quest (preformed at quest Infectious Desease San Juan capistrino CA) 1/29/2018
1:320 Labcorp (preforming lab unknown, collected in Ohio) 1/13/2018
note that Labcorp interpretation criteria states, "The median titer in a population of apparently healthy adults is 1:320"
