I did Equipment Swab and have it tested for Standard Plate Count at an external Lab and the result came out 16-34 cfu as attached. The Reporting Limit as indicated on by outside lab is 1 cfu only.
My problem is I can't find any reference material what should be our internal limit. My questions are the following:
- Do we have to use the reporting limit specified by the outside laboratory? Is this limit set out by regulating agencies (FDA) or we have to set our own?
- Does anyone have a reference material I can read to help me?
Appreciate all your usual help! Thanks!
