Multiple patient encounters should be avoided.
Serum separator tube.
Separate serum from cells ASAP or within 2 hours of collection. Transfer 0.5 mL serum to an ARUP Standard Transport Tube. (Min: 0.25 mL). For multiple allergen orders refer to "Allergen Specimen Collection Instructions" at www.aruplab.com/testing/resources/specimen.
Hemolyzed, icteric, or lipemic specimens.
After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year

|Probability of IgE Mediated
|Less than 0.10||No significant level detected||0|
|0.10 - 0.34||Clinical relevance undetermined||0/1|
|0.35 - 0.70||Low||1|
|0.71 - 3.50||Moderate||2|
|3.51 - 17.50||High||3|
|17.51 - 50.00||Very high||4|
|50.01 - 100.00||Very high||5|
|Greater than 100.00||Very high||6|
Allergen results of 0.10-0.34 kU/L are intended for specialist use as the clinical relevance is undetermined. Even though increasing ranges are reflective of increasing concentrations of allergen-specific IgE, these concentrations may not correlate with the degree of clinical response or skin testing results when challenged with a specific allergen. The correlation of allergy laboratory results with clinical history and in vivo reactivity to specific allergens is essential. A negative test may not rule out clinical allergy or even anaphylaxis.
