WB confirmation results of HIV primary screening reactive specimens using ELISA reagents
| Reactivity number using ELISA initial screening | WB [n (/%)] | |||
|---|---|---|---|---|
|
| ||||
| Confirmed positive | Indeterminant | Negative | ||
| WT single reagent reactivity | 70 | 0 (0.00) | 15 (21.43) | 55 (78.57) |
| XC single reagent reactivity | 69 | 0 (0.00) | 16 (23.19) | 53 (76.81) |
| Dual reagent reactivity | 26 | 23 (88.46) | 1 (3.85) | 2 (7.69) |
| Total | 165 | 23 (13.94) | 32 (19.39) | 110 (66.67) |
Note: There was a significant difference in the WB confirmation results of single reagent reactivity and dual reagent reactivity (x2 = 142.98, P < 0.05); There was no significant difference in the WB confirmation results between two single reagent reactivity (x2 = 0.062, P > 0.05).
