(d) Specificity;

(e) Sensitivity;

(f) Interferences; and

(g) Other related test variables that affect test results; and

(5) Have adequate quality control systems and procedures in place to:

(ii) Strength or concentration;

(iii) Storage requirements;

(iv) Preparation and expiration date;

(v) Identity of the preparer; and

(vi) Other pertinent information that affects test performance;

(b) Store laboratory materials in the manner recommended by the manufacturer;

(c) Test representative samples of each lot of materials used for or in the process of testing blood-spot specimens on a regularly scheduled basis to determine that each lot of test material is capable of performing as required; and

(d) Use supplies, reagents, kits, test systems, and other materials in a manner consistent with the recommendations and instructions provided by the manufacturer.

(3) A permittee may not use supplies, reagents, kits, test systems, or other materials in the testing process that have:
