WB test and in-house ELISA with whole-cell antigen tests are the most reliable tests for the diagnosis of H. pylori infection in children.
In conclusion, the evidence provided in this meta-analysis suggests that, at the current time, both WB test and in-house ELISA with whole-cell antigen are the most reliable tests for the diagnosis of H. pylori infection in children.
Correlation between the anti- Toxoplasma IIF commercial test and in-house IIF was excellent (kappa coefficient = 0.98) and allowed us to compare the antibody titers against both parasites.
Subgroup analyses were carried out by technique, immunoglobulin class, and source of test (commercial and in-house).
In the present study, genital chlamydial infection, as detected by Roche Amplicor test, DFA and in-house PCR assay, was 25.2% among the symptomatic females enrolled.
Approximately 2.0% of IgM seropositivity was detected among parturients in our setting when both anti-dengue virus immunoglobulin M tests (commercial and in-house) were simultaneously positive, according to the recent infection definition of this research protocol.
No statistically significant differences in sensitivity or specificity could be seen between the different tests or between commercial and in-house testing.
Placement tests, both commercial and in-house, are widely adopted in language programs to place students into their appropriate levels (Brown et al. 2004).
All 274 clinical specimens in group I were tested by DFA and in-house PCR.
These tests differ in a number of features: antigen composition (e.g., different H. pylori strains); antigen source (e.g., native or recombinant); protocols for antigen purification; class of immunoglobulin detected (e.g., IgG, IgA, IgM); origin of samples (e.g., serum, saliva, urine); and test source (i.e., commercial and in-house test).
