skin prick test reagents?

An allergen associated with severe symptoms, Cor a 8 (lipid transfer
protein), was not detected on immunoblot in three products, and concentrations
varied by more than a factor 100 as was shown by RAST inhibition. Similar
observations were made for profilin, thaumatin-like protein and a not fully
characterized 38-kD allergen. Ratios of individual allergens were variable among
the nine extracts. SPT showed significant difference, and 6/30 patients displayed
false-negative results using 3/9 products.
CONCLUSION: Variability in the composition of products for the diagnosis of
hazelnut allergy is extreme. Sometimes, allergens implicated in severe
anaphylaxis are not detected by immunoblotting. These shortcomings in
standardisation and quality control can potentially cause a false-negative
diagnosis in subjects at risk of severe reactions to hazelnuts.
