|Reference Intervals for all Components|
(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|
|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.
No compliance statements are in use for this test.
