Hi I was wondering if anyone can help understanding lab test reports.

 

I have been doing some end of life testing and one of the results has come back as 2.4x10^3. I don't understand what this is telling me if anyone could help that would be fantastic.

 

Thanks

Hi Garry,

 

I'm a little confused.

 

By "end of life" did you mean shelf-life ?

If your question is deeper see Charles' queries. However, if you just don't understand the notation, 2.4x10^3. cfu/g means that they found 2,400 yeast or mold colonies per gram of the product tested. It reads "two-point-four times ten to the 3rd power".

 

As to what implications that number has on the testing you were performing, we need a lot more information on why you were performing the testing, what the goals were, how the sample was collected/held, etc.

Hi Parkz,

 

Thks for the link. Good stuff.
