Tests that measure Infliximab Anti-Drug Antibody: Quest Diagnostics 2

Ranges

Each lab publishes a reference range for the population groups it tests, usually the middle 95% of results. These intervals describe that population, not an optimal or healthy target. How ranges differ

Infliximab Anti-Drug Antibody 36301
Serum · Fasting not stated · Turnaround Set up: Tues; Report available: 2-8 days
Method and collection
Method
Chemiluminescent Immunoassay
Preparation
Dietary supplements containing biotin may interfere in assays and may skew results to be either falsely high or falsely low. For patients receiving the recommended daily doses of biotin, draw samples at least 8 hours following the last biotin supplementation. For patients on mega-doses of biotin supplements, draw samples at least 72 hours following the last biotin supplementation. Collect immediately before next scheduled dose (trough specimen).

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.
