FIGURE 7 Comparison of selected specific IgE blood tests Average standardized slope coefficient ImmunoCAP 0.98 ImmunoCAP 0.96 AlaSTAT 0.82 Modified RAST 0.80 Modifiest RAST 0.77 Modified RAST 0.65 To assess the precision and accuracy of commercial blood tests for specific IgE, 26 undiluted serum samples containing variable levels of specific IgE to 17 common allergens were sent on 3 different occasion to 6 laboratories.
These include the CAP System (Pharmacia), AlaSTAT (Diagnostic Products Corp., Los Angeles, CA), and Hy-TECH (Hycor, Garden Grove, CA).
Each of the laboratories used one of three common blood tests--the RAST, AlaSTAT, and ImmunoCap--to test for allergies.
All characterized serum samples were analyzed simultaneously in the Pharmacia CAP system, the DPC AlaSTAT system, and the Esoterix Allergy and Asthma system immunoassays to measure correlation to the described microarray assay.
Currently there are three FDA-licensed systems on the market: the CAP assay marketed by Pharmacia-Upjohn, which has a sensitivity of 75% and a specificity of 91%; AlaSTAT marketed by Diagnostic Products Corp., which has a sensitivity of 79% and a specificity of 95%; and HY-TEC marketed by Hycor Biomedical Inc., giving a sensitivity of 89.8% and a specificity of 67.5%.
In 1993, the prevalence of latex-specific IgE antibodies (detected by AlaSTAT EIA) was found to be 8.9 percent among registered nurses working in acute care areas in a large metropolitan hospital in Detroit (21).
AlaStat (Diagnostic Products Corp., Los Angeles, California) and Rast (radioallergosorbant) are latex sensitivity tests.
Three FDA-approved blood tests for latex-specific IgE antibodies, called IgE immunoassays, are now used: The Pharmacia & Upjohn CAP System, the Diagnostic Products' Alastat and the Hycor Assay.
ALASTAT IR Cook believes England are still alive in the third npower Test against Pakistan, despite a woeful collapse by his fellow barsmen.
