Specimen Validity Testing Sample Clauses
Specimen Validity Testing used to ensure the integrity of the test by measuring pH, creatinine, and specific gravity, and testing for adulterants that may be added to the urine specimen.
Specimen Validity Testing. The Contractor shall perform at no additional charge a specimen validity test on every urine specimen to assess the integrity of the specimen that was provided. The specimen validity test shall be performed and abnormal results shall be defined as either, “diluted”, “adulterated”, and/or “substituted” as recommended by the Substance Abuse Mental Health Services Administration. The specimen validity test must include, at a minimum, the creatinine concentration, specific gravity and pH level. All adulterated and diluted specimens shall be screened and the Contractor shall attempt to identify the adulterant.
1) Substituted: Creatinine < 2.0 Specific Gravity ≤ 1.0010 or ≥ 1.0200
2) Invalid: Creatinine < 2.0 Specific Gravity >1.0010 and > 1.0200 Creatinine ≥ 2.0 Specific Gravity ≤1.0010 pH ≥ 3.0 but < 4.5 pH ≥ 9.0 but <11.0 3) Adulterated: pH < 3.0 pH ≥11.0
4) Dilute: Creatinine < 20 Specific Gravity <1.0030
