Patients with a chronic form of urticaria who are positive with the functional Histamine Release (Chronic Urticaria) test have an autoimmune basis for their disease. A positive result does not indicate which autoantibody (anti-IgE or anti-Fc epsilon RI alpha chain) is present. A positive anti-IgE antibody does not exclude the presence of anti-Fc epsilon RI alpha chain antibody. Autoimmune thyroid disease coexists in approximately 25% of autoimmune chronic urticaria patients.

Serum should be separated from the cells as soon as possible
after visible clot formation (usually 15-30 minutes after
collection).

Patient Preparation: Overnight fasting is preferred. Patients
taking calcineurin inhibitors should stop their medication
for 72 hours prior to draw.

Specimen collection after fluorescein dye angiography should be
delayed for at least 3 days. For patients on hemodialysis, specimen
collection should be delayed for 2 weeks. According to the assay
manufacturer Siemens: "Samples containing fluorescein can produce
falsely depressed values when tested with the ADVIA Centaur TSH3
Ultra assay."
