I would say NMT 1 cfu or <1 cfu. How to report also depends on your 
established alert level. Also do you take the average of the 5 flasks in 
your final result?

[PMFLIST] Reporting of one overall bioburden result when you have multiple 
results

Hi all

 

Example (simplified):

 

You have 100 plastic components.

 

You use 5 flask and test 20 components per flask.

 

You get these results:

 

1: 0 CFU

2: 0 CFU

3: 0 CFU

4: 0 CFU

5: 0 CFU

 

Should you report the overall results as:

 

(0+0+0+0+0) = 0 CFU

or if you say that 0 CFU = NMT 1 CFU

 

(NMT 1+ NMT 1+ NMT 1+ NTM 1+ NMT 1) = NMT 1 CFU

 

or 

 

(NMT 1+ NMT 1+ NMT 1+ NTM 1+ NMT 1) = NMT 5 CFU

 

or if NMT 1 CFU = 1 when used in calculations 

 

(1+1+1+1+1) = 5 CFU

 

???

 

I'm confused..

 

Best regards
