and guideline requirements for manufacturers and laboratories performing these tests
have been set forth by the Food and Drug Administration and the Clinical Laboratory
Improvement Amendment of 1988. These measures have assisted in ensuring more consistent
results but do not address either accuracy or precision parameters in a comprehensive
fashion. In summary, one of the major challenges in the development of consistent
allergy testing is the need to identify and accept a well-recognized test standard.
An ideal immunoassay for specific IgE antibodies should meet certain analytic performance
criteria. These criteria include a slope of unity over the useful measurement range
for all allergens, low variation across replicate measurements, statistically determined
limits of detection, a practical cut-off point, and defined saturation points. For
an assay to be considered as a standard, it would require close approximation to these
criteria. There is currently no established standard in this field.;
