1. (a) A marijuana testing facility shall use the general body of required laboratory tests as set out in this section for marijuana plant material, an extract or concentrate of marijuana, and a marijuana product. Required tests may include potency analysis, moisture content, foreign matter inspection, microbial screening, pesticide, other chemical residue, and metals screening, and residual solvents levels. A marijuana testing facility shall establish a schedule of fees required for each test it offers, and shall perform tests using methods in compliance with guidelines prescribed by the board.

2. (b) The tests required for each marijuana type or marijuana product, are as follows:

   1. (1) potency testing is required on marijuana bud and flower, marijuana concentrate, and a marijuana product, as follows:

      1. (A) the required cannabinoid potency test must at least determine the concentration of THC, THCA, CBD, CBDA, and CBN cannabinoids; a marijuana testing facility may test and report results for any additional cannabinoid if the test is conducted in compliance with a validated method;

      2. (B) a marijuana testing facility shall report potency test results as follows:

         1. (i) for a potency test on marijuana and marijuana concentrate, the marijuana testing facility shall list for each required cannabinoid a single percentage concentration, based on dry weight, that represents an average of all samples within the test batch; additionally, total THC and total CBD shall be reported.
         2. (ii) for a potency test on a marijuana product, whether conducted on each individual production lot or using process validation, the marijuana testing facility shall list for each cannabinoid the total number of milligrams contained within a single retail marijuana product unit for sale;
         3. (iii) for testing whether the THC content is homogenous, the marijuana testing facility shall report the THC content of each single serving in a multi-unit package; the reported content must be within 20 percent of the manufacturer's target; for example, in a 100 milligrams total THC package with 10 servings, each serving must contain between eight and 12 milligram of THC;

      3. (C) the marijuana testing facility shall determine an edible marijuana product to have failed potency testing if

         1. (i) an individually packaged edible retail marijuana product with 10 servings that is contained within a test lot is determined to have more than 120 milligrams of THC within it; or
         2. (ii) the THC content of an edible marijuana product is not homogenous;
   2. (2) microbial testing for the listed substances on the listed marijuana and marijuana products is required as follows:
   3. (3) testing for the listed residual solvents and metals on the listed marijuana products is required as follows:
