Endpoint dilutions^* of IgM detection on three sera and two CSF

Sample	Type†	CDC	Panbio	XCyton	InBios	Panbio Adjusted
1	High serum	> 12,800	3,200	6,400	> 12,800	N/A
2	High serum	> 12,800	200	1,600	> 12,800	N/A
3	High serum	> 12,800	3,200	> 12,800	> 12,800	N/A
4	High CSF	> 1,280	40	20	320	20
5	Low CSF	80	10	< 10	< 10	10

^*Endpoints are given as the reciprocal of the highest dilution at which Japanese encephalitis virus (JEV) IgM was detected by the assay from an initial serum dilution of 1:100 diluted 4-fold to 1:12800 and initial cerebrospinal fluid (CSF) dilution of 1:10 diluted 2-fold to 1:1280. Endpoints of > 12,800 (sera) or > 1,280 (CSF) indicate that JEV IgM was detected by the assay to the final dilution of the analysis.

^†Based on initial Centers for Disease Control and Prevention (CDC) Japanese encephalitis virus (JEV) IgM antibody capture enzyme-linked immunosorbent assay (MAC ELISA) results at 1:400 (sera) and 1:10 (CSF) screening dilutions. High serum or CSF, P/N > 20; low CSF, P/N < 10.
