a
Serum samples were either mock (N) or adsorbed (Y) with ectodomain pH1/H3 rHA‐conjugated latex beads.
b
Sensitivity was determined by the highest fold rise for H5 GH HA1 in MFI and DPP values (≥2 fold).
c
Cross‐reactivity was determined by the highest fold rise for unexposed antigens in MFI and DPP values (≥2 fold).
d
Specificity was determined by the highest fold rise for H5 GH HA1 in MFI and DPP values (≥2 fold).
e
Sera were collected from H5N1‐infected persons that showed seroconversion to A/BD/3233/2011 (H5N1) in MN.
f
Sera were collected from persons that showed seronegative to A/BD/3233/2011 (H5N1) in MN.
