Reactivities of the 60-kDa band in IgG and IgG4 blots of native protoscolex antigen probed with sera from hydatid cyst patients and with control sera
| HRP-conjugated secondary antibody | No. of reactive or nonreactive sera/total no. of sera examined (%)a |
|
|---|---|---|
| Group II, sensitivity | Group III, specificity | |
| IgG4 | 42/49 (86) | 68/68 (100) |
| IgG | 10/30 (33) | 68/68 (100) |
a
Sensitivity was determined as the number of sera reactive with the band/the total number of sera tested. Specificity was determined as the number of sera nonreactive with the band/the total number of sera tested. Group II was composed of sera from patients with hydatid cysts confirmed by surgery. Group III was composed of sera from healthy people and from patients with other parasitic infections (controls).
