Transcript of "Adulterant%20 survey%20algorithm"

  1. 1. Adulterant Survey Algorithm Urine specimen tested for: Creatinine Oxidants and Specific gravity pH Negative Positive pH <3.0 Creatinine <2.0 Creatinine <5.1 Creatinine 2.0 - 19.9 Creatinine 20.0 - 200.0 Creatinine >200.0 pH >11.0 or and or and or Specific gravity <1.001 Specific gravity >1.020 Specific gravity 1.001 - 1.002 Specific gravity 1.003 - 1.035 Specific gravity >1.035 and pH 3.0 - 11.0 No additional Presence of an Abnormally low pH Specimen Suspect specimen Specimen No additional Specimen unusually Abnormally comment attached oxidant detected Suspect specimen unusually dilute substitution unusually dilute comment attached concentrated high pH to report Suspect specimen adulteration Suspect to report Suspect adulteration specimen specimen substitution adulteration Nitrite Negative Positive No additional Presence of comment nitrite detected attached to Suspect report specimen adulteration Drug of abuse tests performed in the Toxicology Laboratory are used to monitor compliance with treatment programs and should be utilized in a clinical setting where test results can be used definitively to make a diagnosis. Specimen adulteration can have a significant, potentially damaging, effect on treatment decisions. For this reason, the Toxicology Laboratory utilizes a multistep process to evaluate specimens for adulteration. The specimen adulteration evaluation involves the following tests: creatinine, specific gravity, pH, and oxidants. When 1 or more of these results are outside the normal reference value, an adulterant comment is added to the final report that identifies the specific adulterant found. 05/10
