(reported in kU/L)
|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.
This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.
