Minimal cross-reactivity at the IgM or the IgG level1 • Although serological cross-reactivity across the flavivirus group is common, in clinical trails the Panbio Dengue Rapid Strip Test showed no cross-reactivity with samples from patients with Japanese encephalitis.

Commonly Asked Questionsabout Panbio dengue tests... QWhat happens if I don’t read the Dengue Rapid Tests at the correct time (ie 15 minutes for cassette and 15 – 30 minutes for strip)? Why do bands appear if I leave the test overnight? ABands appear due to lower levels of specific IgG or cross-reactive antibody.
Commonly Asked Questionsabout Panbio dengue tests... QHow do I interpret faint lines in the Dengue Rapid Tests? AAny Sign of a line is a positive result.
Commonly Asked Questionsabout Panbio dengue tests... Q In the Panbio Dengue Duo ELISA and Dengue Rapid Tests, why don’t symptomatic donors from endemic areas show elevation of IgG? A IgG Cutoff set above the level in Primary and Past Dengue.
Commonly Asked Questionsabout Panbio dengue tests... QHow do the cutoffs of these tests compare with haemagglutination-inhibition assays? AIgG Cutoff = HAI Titre for 2° Dengue (e.g. HAI 1:2560).
Commonly Asked Questionsabout Panbio dengue tests... Q Do I need to use both IgM and IgG for the diagnosis of dengue infection? Why can’t I just use IgM? ASome cases of secondary dengue do not show detectable IgM.
