ADULTERATION OF URINE DRUG TESTING: CASE REPORT AND REVIEW

Öz

Drug tests are conducted for individuals having suspected intoxication, having suspected drug use, involving in an accident, being in probation control; applicants during recruitment and prisoners. However, the validity of these tests depend on the urine sample’s being uninterferenced. Because, illicit drug users add easily available common foreign substances(adulterants) into the urine to deceive these tests. Adulterants are classified into two categories. The first category includes classic adulterants comprising of some household chemicals such as chlorine bleach, white vinegar, glutaraldehyde, liquid drain cleaner, sodium nitrite, pyridinium chlorochromate. The second category includes commercial products which can be purchased from certain specialty stores or via internet. Dilution of urine by means of excess water intake is the most basic method used for adulteration. The case we present tried to falsify the result two times by drinking water and once by giving the urine of a different person for the analysis. Adulterant use can be disclosed by presumptive tests such as specific gravity, pH, temperature, creatinine, nitrite, glutaraldehyde levels which are useful for determining whether the urine sample is interferenced or not. Urine dilution in our case is disclosed by the abnormal creatinine concentration of less than 20 mg/dL. This case was presented to draw attention for adulterant use which is not common and well known by scientists in Turkey.
