Table 1. Interpretative criteria.

Difference Value (D)	Suitability for identification	Identification	Interpretation
0.0 ≤ D ≤ 0.28	High	All identification results within this range have the same possibility of being the bacterial isolate	Matched the bacteria registered in the database
0.28 < D ≤ 0.5		The identification result with the lowest Difference Value is highly likely to be the bacterial isolate	Mutant strain, or Polymicrobial infection*1
0.5 < D	Not suitable	Does NOT identify the bacterial isolate	Polymicrobial infection*2, or Not registered in the database, or Under the limit of identification*3

^*1Polymicrobial infection with one dominant bacterial species.

^*2Polymicrobial infection with no dominant bacterial species.

^*3Under the limit of identification, but over or equal to the limit of detection.
