*Although we no longer maintain a ready-to-order stock of this control, we offer PH Check Controls for use with drug screens on a made-to-order basis through our Custom QC program.
A pH check is utilized in drugs of abuse (DOA) screening to determine that an adulterant has not been added to change the specimen’s pH and interfere with the test’s accuracy. Also, water is a common adulterant which can be determined by measuring urine creative and specific gravity.
