  • Acetylcholine Receptor (AChR)-binding Antibodies 085902

    Serum · Fasting not stated · Turnaround 2 - 4 days

    Method and collection
    Method
    This assay measures antibodies that precipitate solublized muscle AChR that has been complexed with radiolabeled alpha-bungarotoxin (αBTX). Antibodies that bind to the receptor regions that are not sterically blocked by the αBTX are detected.
    Preparation
    No isotopes administered 24 hours prior to venipuncture
    Collection
    If a red-top tube is used, transfer separated serum to a plastic transport tube.
    Reference notes
    • Negative: 0.00−0.24 nmol/L • Borderline: 0.25−0.40 nmol/L • Positive: >0.40 nmol/L

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.
