MICROBIOLOGY REMARK CODES EXPLANATION The
use of remark codes is required for all bacterial analysis as needed. These
codes are necessary when the sample filtered has a high amount of non-target
bacterial growth. This non-target growth (Background bacteria) may interfere
with the detection and/or enumeration of the target bacteria (E. coli).
As a result, the CFU/l00mL reported must be qualified with
A2C and/or A3C (If needed). This indicates that the reported result is approximate.
A2C
(Background Counts
200): This code is used when the non-target bacterial growth on
the filter exceeds 200 colonies. This background growth may interfere with
the growth and/or proper enumeration of the target colony.
: This code is used when the non-target bacterial growth on the
filter exceeds 200 colonies. This background growth may interfere with the
growth and/or proper enumeration of the target colony.
A3C (Approximate Result: Total Count Exceeds 300 Colonies: Colonies: This code is used when the target colony (E. coli) on the filter is <150, but a total colony count (including both the target and non-target colonies) exceeds 300 colonies. Again, the presence of the background bacteria may interfere with growth and/or enumeration of the target colony.
CFU/l00mL: Colony forming units per l00mL. This is the visible bacterial growth that is counted and reported per l00mL of sample.
Non-target colony: Refers to any bacteria (Background bacteria) which we are not testing for. Any bacterial growth which is not E. coli. |
