Zuccala

  9. METHADONE • Synthetic opioid used to treat opioid dependence (Dolophine, Methadose) • Easy to overdose on: low levels can cause difficulties in breathing and swallowing, low pressure, coma even death • Reported positive on the urine screen panel if concentration exceeds 300 ng/mL • Confirmation metabolites: methadone and EEDP • Detection window 1-4 days J. Zuccala

Zuccala

  17. CARISOPRODOL (SOMA) • Muscle relaxant • Used to treat injuries and painful muscle conditions • Habit-forming and often abused drug • Reported positive on the urine screen panel if concentration exceeds 100 ng/mL • Window of detection 1-2 days J. Zuccala

  18. Ketamine • Ketanest, Ketaset, Ketalar (street name “Special K”) • Use in veterinary and human medicine for anesthesia, analgesia and sedation • Similar to PCP, it induces “dissociative anesthesia” and therefore used as recreational drug • Window of detection 1-2 days J. Zuccala

  19. TRAMADOL • Ultram, Tramal, Ryzolt • Used as centrally acting synthetic analgesic and in opioid dependency treatments • Reported positive on the urine screen panel if concentration exceeds 200 ng/mL • Window of detection 2-4 days J. Zuccala

  20. FENTANYL • Actiq, Duragesic, Fentora, Sublimaze • Extremely strong synthetic opioid, often prescribed in pain management clinics • Reported positive on the urine screen panel if concentration exceeds 2 ng/mL • Exist as a transdermal patch and lozenges (lollipop) • Window of detection 1-3 days J. Zuccala

  21. MEPERIDINE • Meperitab, Demerol, Mepergen • Meperidine is an opioid and a controlled substance with an abuse liability similar to morphine. • Reported positive on the urine screen panel if concentration exceeds 200 ng/mL • Window of detection 1-2 days J. Zuccala

  22. Methylphenidate • Ritalin, Concerta, Daytrana • Psychostimulant drug approved for treatment of ADHD, lethargy, narcolepsy, depression and obesity • Methylphenidate is sometimes used by students to enhance their mental abilities, improving their concentration and helping them to study • Confirmation of methylphenidate in urine serves to monitor compliance in those receiving the drug therapeutically • Window of detection 1-2 days J. Zuccala

  23. TRICYCLIC ANTIDEPRESSANTS (TCA) • Pamelor, Elavil, Sinequan, Trofanil • Generally low abuse potential • Used as antidepressants, in ADHD therapy and for chronic pain • Reported positive on the urine screen panel if concentration exceeds 300 ng/mL • Window of detection 2-19 days J. Zuccala

  24. Synthetic Cannabinoids • K2, Spice, Black Mamba, Fake Weed, Genie, Bombai Blue… • Psychoactive designer drug derived of natural herbs sprayed with synthetic chemicals • Illegal to posses or use in the U.S. • Synthetic cannabinoid intoxication is associated with acute psychosis, worsening of previously stable psychotic disorders, and also may have the ability to trigger a chronic (long-term) psychotic disorder among vulnerable individuals such as those with a family history of mental illness. • Window of detection up to 72 hours J. Zuccala

  25. Bath Salts • Ivory Dove, Vanilla Sky, Blue Silk, Cloud Nine, Hurricane Charlie, Drones… • “Street name” for the family of designer drugs containing substituted cathinones • Produce effects similar to amphetamines and cocaine • Banned in at least 41 states • Window of detection 2-3 days J. Zuccala

  26. Cotinine • Metabolite of nicotine, also found in tobacco • Cotinine is used as a biomarker for exposure to tobacco smoke and has also been sold as an antidepressant under the brand name Scotine. • Cotinine levels <10 ng/mL are considered to be consistent with no active smoking. Values of 10 ng/mL to 100 ng/mL are associated with light smoking or moderate passive exposure, and levels above 300 ng/mL are seen in heavy smokers - more than 20 cigarettes a day. In urine, values between 11 ng/mL and 30 ng/mL may be associated with light smoking or passive exposure, and levels in active smokers typically reach 500 ng/mL or more. • Window of detection in urine is up to 7 days J. Zuccala

  27. VALIDITY TESTING-pH • pH test measuring acidity of urine (normal values between 4.5 and 8.9). If pH found to be lower than 4.5 or higher than 8.9, the specimen is considered adulterated • Adulterants that change pH of urine- any acid or base (lemon juice, soap, house cleaning products, etc) J. Zuccala

  28. VALIDITY TESTING-OXIDANTS • Oxidants test for the presence of oxidizing agents such as bleach and hydrogen peroxide. Normal human urine should not contain oxidants or PCC • Cutoff of the assay on instrument is 50 µg/mL • Adulterants that change oxidant levels of urine are Pyridiniumchlorochromate (sold under the brand name UrineLuck), bleach, etc. J. Zuccala

  29. VALIDITY TESTING-NITRITES • Nitrites test is testing for the presence of nitrite salts in urine sample (certain foods and meats contain nitrites) • Normal humane urine doesn’t contain any nitrites • Instrument cutoff is 500 µg/mL • Adulterants containing nitrites are Klear, Whizzies, etc. J. Zuccala

  30. VALIDITY TESTING-SPECIFIC GRAVITY • Specific gravity tests for sample dilution. The normal range is from 1.003 to 1.020. Values outside this range may be the result of specimen dilution or adulteration. • Factors affecting specific gravity are dehydration, excessive sweating, increased water intake, etc. • Trident lab is currently phasing specific gravity out, due to the fact that this test can be easily manipulated with. J. Zuccala

  31. VALIDITY TESTING-CREATININE • Creatinine is a waste product of creatine; an amino-acid contained in muscle tissue and found in urine. A person may attempt to foil a test by drinking excessive amounts of water or diuretics such as herbal teas to “flush” the system. Creatinine and specific gravity are two ways to check for dilution and flushing, which are the most common mechanisms used in an attempt to circumvent drug testing. Low creatinine and specific gravity levels may indicate dilute urine. • The absence of creatinine(<2mg/dl) is indicative of a specimen not consistent with human urineand is considered substituted (apple juice, etc.) J. Zuccala
