a
Identical results were obtained by detection by real-time mono-NASBA and by electrochemiluminescence.
b
No. 10 was excluded from analysis.
c
All operations were performed in separate rooms, except for participant 7, who used a single room.
d
0 = 0; 1 = 1 to 10 samples monthly; 2 = 11 to 45; 3 is more than 50.
