Method
The Thermofisher/BRAHMS KRYPTOR® assay employs Time-Resolved Amplified Cryptate Emission Cryptate Emission (TRACE) technology based on a non-radioactive energy transfer between a donor (europium cryptate) and an acceptor (XL665) in a sandwich immunofluorescent format using two mouse monoclonal antibodies.37-40 This assay is calibrated against recombinant human CG, and according to the manufacturer's package insert.1
Collection
Transfer separated serum to a plastic transport tube.

Verify these ranges and sources

We compile this page from named laboratory catalogs, guidelines and studies. Labs calculate reference intervals from the people they test, for one assay method and one population group, so an interval describes that population rather than an optimal target.
