Specimen

  
Serum
  
  
1.0 mL
  
0.3 mL
  
  • For more than one allergen, use this formula to calculate the amount of serum required:

50 µL X (# of allergens) + 250 µL = total amount serum needed

  • Immediately following collection, thoroughly mix sample by gently inverting 5 times
  
  1. Allow sample to clot for a minimum of 30 minutes
  2. Spin within two (2) hours of sample collection
  

Gold serum separator (SST) tube

  
Lithium heparin (Li hep) plasma
EDTA plasma (acceptable, but not preferred)
  

Red serum vial/tube - 5 mL

Lt green plasma separator (PST)

Lavender (EDTA), 4mL

Red/grey serum separator (SST) vial/tube, 10 mL

  

Lt green/Lavender:

Immediately following collection, mix sample thoroughly by gentle inverting 8 - 10 times to prevent clotting

  

Red:

  1. Allow sample to clot
  2. Spin
  3. Transfer serum to a False bottom plasma/serum transport vial/tube (AHL), labelled as serum, within two (2) hours of sample collection

Lavender:

  1. Spin
  2. Transfer plasma to a False bottom plasma/serum transport vial/tube (AHL), labelled as EDTA plasma, within two (2) hours of sample collection

Lt green:

  1. Spin
  

False bottom plasma/serum transport vial/tube (AHL)

Lt green plasma separator (PST)

Red/grey serum separator (SST) vial/tube, 10 mL

<0.35 kU/L

  

Allergy class severity values

ImmunoCAP IGE Class Reference Values:

Traditionally, allergen tests have been reported with an associated class value of zero to 6, with Class 0 indicating an undetectable allergen level, and Class 6 indicating a strong positive allergen level.

The following chart correlates ImmunoCAP IgE allergen results in kU/L to the associated class, with a suggested interpretation. This chart is applicable to all allergen-specific tests at Allina Health Laboratory, which are performed exclusively on ImmunoCAP assays. Note that the Class Reference Values provided are specific for ImmunoCAP assays and may not be used to interpret allergy tests performed by other (non-ImmunoCAP) methods.

 

 Class  IgE kU/L  Interpretation
0  <0.35  Undetectable
1  0.35 - 0.70  Equivocal
2  0.71 - 3.50  Positive
3  3.51 - 17.50  Positive
4  17.51 - 50.00  Strong positive
5  50.01 - 100.00  Strong positive
6  >100.00  Strong positive
