Limitations
Results in the range of 0.10-0.34 kU/L are for specialist use due to undetermined clinical relevance. Allergen-specific IgE concentrations may not directly correlate with clinical response severity or skin test results. Negative tests do not rule out the possibility of allergies or anaphylaxis. Interpretation should be combined with clinical evaluation.
