Diagnosis of allergic diseases
IAST®
(Inhalation Allergy Screen Test)
Allergy of the respiratory system (e.g. asthma or rhinitis) often
presents with an unclear, confusing picture, making the correct diagnosis
difficult. Eurolab Ltd. introduces a clear solution to this situation: IAST®.
IAST® is a highly efficient test for the differential
diagnosis of inhallant allergy. It is an in vitro Reversed EIA test in microplates
manual or automated. A single blood
sample of 0.50 ml is sufficient to perform the assay. Results are expressed
in allergy units (AU/L). The normal value is 0-35 AU/L (mean: 12.6 AU/L*).
However the mean value for allergic individuals has been found 876.3 AU/L*. In contrast with conventional screening tests for breathing allergy
(e.g. Phadiatop®), IAST® can distinguish between
seasonal (pollen) and perennial allergy. The results of clinical studies show that IAST® has a 95.5%
sensitivity* and a 100% specificity (no false positives*). ------------------------------------------------------------------------------------- (*) Eurolab
