LAB4017
Collect
Serum separator tube. Multiple specimen tubes should be avoided.
Patient Preparation
Multiple patient encounters should be avoided.
Specimen Preparation
Separate serum from cells ASAP or within 2 hours of collection. Transfer 0.25 mL serum plus 0.1 mL for each additional allergen ordered to an ARUP Standard Transport Tube. (Min: 0.25 mL plus 0.04 mL for each allergen ordered)
Unacceptable Conditions
Hemolyzed, icteric, or lipemic specimens.

| Reporting Range (reported in kU/L) | Probability of IgE Mediated Clinical Reaction | Class Scoring |
|---|---|---|
| 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 |
Interpretive Data
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.
