Helicobacter pylori

Overview

Helicobacter pylori  Testing

Pylori Detect IgG and IgA EIAs

Assay Precision

The intra- and inter-assay precision were calculated by running three patient sera (negative, low positive, and high positive) in 24replicates using two independent operators. The following results were obtained:


Pylori Detect IgG

  Serum 1 Serum 2 Serum 3
Operator 1 CV Intra-Assay 3.85% 4.79% 1.39%
Operator 2 CV Intra-Assay 3.22% 5.91% 1.56%
Inter-Assay CV 4.35% 6.86% 5.53%


Pylori Detect IgA

  Serum 1 Serum 2 Serum 3
Operator 1 CV Intra-Assay 7.94% 2.81% 4.94%
Operator 2 CV Intra-Assay 4.43% 2.97% 4.42%
Inter-Assay CV 7.61% 4.19% 4.86%


Interpretation of Results Using ELISA Values

≥1.0 Positive
0.89–0.99 Equivocal (retest the specimen)
<0.89 Negative
