showed this dot immunogold filtration assay for sparganosis mansoni has light cross-reactivity to clonorchiasis (8%) and serious cross-reactivity to paragonimiasis (52%).
In-house testing demonstrates that this kit is highly sensitive to anti-Zika virus IgG and displays minimal cross-reactivity with dengue virus IgG antibodies.
The purpose of this study was to comprehensively and systematically evaluate the specificity of BNP, NT-proBNP, and proBNP assays by determining cross-reactivity with a variety of glycosylated and nonglycosylated natriuretic peptides and NP fragments.
These findings are supportive of those described by De Brito and colleagues, (4) who described the cross-reactivity of the spirochetes of intestinal spirochetosis with both anti-T pallidum and antiLeptospira interrogans antibodies.
The assay was developed based on available DNA sequence information from the Internal Transcribed Spacer (ITS) region, and tested against a variety of species within the Prunus genus to ensure no cross-reactivity.
Cross-reactivity between flaviviruses has been reported in antibody assays and in tests for Dengue nonstructural 1 glycoprotein (NS1) antigen.
1994) revealed a considerable cross-reactivity between cricket and grasshopper allergens.
In a study (2) that examined cross-reactivity of naloxone with oxycodone immunoassays, researchers proposed that urine samples with a high naloxone concentration produced higher cross-reactivity with oxycodone.
There also was some cross-reactivity with raw poultry meat.
There was cross-reactivity with other sulfa antibiotics: Seven of 18 patients with prior sulfamethoxazole allergy reacted to oral challenge with sulfadiazine, and 4 of 9 patients with prior allergy with sulfamethoxazole reacted to challenge with sulfamethazine.
But this appears to be due to overall increased reactiveness and not a cross-reactivity, because those with history of penicillin allergy had an even higher allergy rate to sulfa nonantibiotics than did patients with a prior sulfa allergy.
The immunodiagnosis of T vivax is often performed by the ELISA test using soluble antigenic extract of T evansi because of the high antigenic cross-reactivity and the ease of replicating T evansi in rodents to obtain the crude extracts [11, 14, 19], but there have been few attempts to determine the differences in the type of antigen preparation or of the particular isolate from which the antigen is derived.
