Test Sample Size Guidelines

By Rachel Corn, VT

To ensure the best possible results from testing, a correct sample size is necessary. Some tests can be completed on a very small amount of sample, while others require a larger section.

Below is a table with some of the common tests and the appropriate sample size. If you are requesting that more than one test be completed on a single sample, a larger sample will be required. In all cases, it never hurts to send an extra sample, in case additional testing is needed.
