There is lack of accurate serological diagnosis of the Zika virus due to cross-reactivity with other flaviviruses. We tested three commercially available anti-ZIKV IgG ELISA kits currently on market. Contrary to the manufacturers' claims, we find that these kits have either high cross-reactivity with dengue virus or low Zika virus sensitivity.
We have developed an Anti-Zika IgG test that is highly sensitive to Zika and displays minimal cross-reactivity with anti-dengue virus IgG. R&D Systems® Anti-Zika Virus IgG test will potentially allow for a highly specific serological test for Zika virus.
