What information do laboratories report to MROs regarding split specimen results?

(a) As the laboratory responsible for testing the split specimen, you must report split specimen test results by checking the “Reconfirmed” box or the “Failed to Reconfirm” box (Step 5(b)) on Copy 1 of the CCF.

(b) If you check the “Failed to Reconfirm” box, one of the following statements must be included (as appropriate) on the “Reason” line (Step 5(b)):

(1) “Drug(s)/Drug Metabolite(s) Not Detected.”

(2) “Adulterant not found within criteria.”

(3) “Specimen not consistent with substitution criteria [specify creatinine, specific gravity, or both]”

(4) “Specimen not available for testing.”

(c) As the laboratory certifying scientist, enter your name, sign, and date the CCF.
