title: Circulating thyroid hormones in a patient with hyperviscosity syndrome.
abstract: The elevated T4 levels by one RIA in the patient with hyperviscosity syndrome were probably caused by the interference of the increased protein concentration in the T4 assay rather than by hyperthyroidism or binding of T4 by immunoglobulins.
