The results of analysed samples are presented in appendix B.
Results obtained after VIDAS LMX + Chrom’ID Ottaviani Agosti (bioMérieux) confirmations or VIDAS LMX +
Rapid’
L.mono
(BIORAD) confirmations
were similar, except for one sample (C7, which was confirmed only on
Rapid’
L.mono
).
The overall results are shown in the summary table below :
Positive reference method
(R+)
Negative reference method
(R-)
Positive alternative method (A+)
Positive agreement
(A+/R+)
PA = 153
Positive deviation
(R-/A+)
PD = 19
Negative alternative method (A-)
Negative deviation
(A-/R+)
ND = 18*
Negative agreement
(A-/R-)
NA = 194*
Legend :
A+ = positive confirmed
A- = immediate negatives
and
negatives after confirmation when presumed positive
* which no positive VIDAS LMX unconfirmed
