Allergen Panel, IgE by ImmunoCap ISAC : 2005894

Mnemonic: ISAC MICRO

Methodology: Semi-Quantitative ImmunoCAP® Solid-phase Allergen Chip
Performed: Varies
Reported: 3-6 days
Specimen Required: Collect: Serum separator tube. Also acceptable: Lavender (EDTA) or green (sodium or lithium) heparin.

Specimen Preparation: Transfer 0.4 mL serum or plasma to an ARUP Standard Transport Tube. (Min: 0.25 mL)

Storage/Transport Temperature: Refrigerated. Also acceptable: Frozen.

Unacceptable Conditions: Ambient specimens.

Reference Interval:
By report
Note: Method Description: The method uses solid-phase immunoassays against 112 antigenic epitopes and measures IgE antibody concentrations in patient serum or plasma. The binding of a specific IgE to an immobilized allergen component is detected by the addition of a secondary fluorescence-labeled anti-human IgE antibody. Results are reported in ISAC Standardized Units (ISU).
