Table 3. Test outcomes in class-specific LFRET tests compared with the reference tests.

a)	Anti-ZIKV-IgM-positive (n = 11)	Anti-ZIKV-IgM-negative (n = 102)	b)	Anti-ZIKV-IgG-positive (n = 19)	Anti-ZIKV-IgG-negative (n = 84)
Acute-LFRET positive	100% (n = 11)	4% (n = 4)	Immunity-LFRET positive	95% (n = 18)	0% (n = 0)
Acute-LFRET negative	0% (n = 0)	96% (n = 98)	Immunity-LFRET negative	5% (n = 1)	100% (n = 84)

a) Acute-LFRET outcomes vs. IgM-reference tests

b) Immunity-LFRET outcomes vs. IgG-reference tests
