Standard Methodology for the Determination of Tea Flavonoids
The following two labs have undergone extensive training and are qualified to use the test methodology. While other labs may have the capability, the test is quite sensitive and results are prone to a significant degree of variability if the methodology is not precisely applied. At this time, we recommend that our membership utilize the services of these two labs.

Important Note:
When scheduling your tests, it is a good idea to remind your technician
that you want to see the final results after the 0.84 correction factor
has been applied. This is an important step that is easily overlooked.
