I will dilution for microbiology testing but sometimes during reading of plate, i encounter that plate

10^1: has no growth

10^2 : has 10 colonies (for an example)

how should i read the result? should i assume 10^1 has no growth or TNTC?

Thank you.

Phil Geis

You must respect your data - certainly not assume TNTC when you have no colonies. This is absolutely inappropriate.

10 is not in countable range.

Think your data are not useful - do it over.
