Group 1: Patients with AGS symptoms after being exposed to potential sources of alpha-gal
Group 2: Patients without AGS symptoms after being exposed to potential sources of alpha-gal
aTrue positive: patients with AGS symptoms after exposure to a source of alpha-gal with values sIgE ≥ 0.1 KUA/L
bFalse positive: patients without AGS symptoms after exposure to a source of alpha-gal with values sIgE ≥ 0.1 KUA/L
cFalse negative: patients with AGS symptoms after exposure to a source of alpha-gal with values sIgE < 0.1 KUA/L
dTrue negative: patients without AGS symptoms after exposure to a source of alpha-gal with values sIgE < 0.1 KUA/L
