SUBCHAPTER ETESTING
RULE §24.26Methods for Testing

(a) Laboratories shall use appropriate, validated methods and procedures for all testing activities and evaluate the measurement of uncertainty.

(b) At a minimum, analytical testing of samples for delta-9 tetrahydrocannabinol concentration levels must use post-decarboxylation or other similarly reliable methods approved by the Department.

(c) The testing methodology must consider the potential conversion of delta-9 tetrahydrocannabinolic acid (THCA) in hemp into delta-9 tetrahydrocannabinol (THC) and the test result reflect the total available THC derived from the sum of the THC and THC-A content. Testing methodologies meeting these requirements include, but are not limited to, gas or liquid chromatography with detection.

(d) Alternative testing protocols will be considered by the Department if they are comparable and similarly reliable to the baseline established under the Department program. Alternative testing protocols must be requested of the Department in writing and approved in writing by the Department, provided they meet the requirements of this subchapter.
