Urine Drug Screens

Our laboratory is known for its accuracy in pinpointing drugs in urine. We test for numerous drugs including but not limited to:

  • Alcohol
  • Amphetamines
  • Barbiturates
  • Benzodiazepines
  • Cannabinoids
  • Cocaine
  • Methadone
  • Opiates
  • Oxycontin
  • PCP
  • Phenothiazines
  • Propoxyphene

Alternate confirmatory testing allows us to identify specific drugs in the above classes such as Clonazepam, Clonopin, Pseudoephedrine, etc. Different methods of confirmation testing performed are gas chromatography, high performance liquid chromatography, thin layer chromatography, or GC/MS.

Adulteration comes in many disguises. Where collections are not as closely observed, donors can put numerous adulterants into urine, such as bleach, chromates, nitrites, glutaraldehyde, etc. It is probably not possible to detect every single adulteration, but we at CSL know our tests for all of the above, and more, make for highly reliable screening results. Any suspicious sample is run through our adulterant panel to check for dilution and for the substances listed above. CSL offers one of the most comprehensive adulterant panels in New England for samples that deserve such scrutiny. Our highly trained technicians perform initial screens for adulteration that indicate further testing when it is needed. We are usually able to outwit the cheaters. It’s all part of paying attention to detail.

Having worked with many court-involved clients, utilizing a chain of custody is something our lab is very familiar with. Whether it is a simple signature or a 5-part form, we can complete it and maintain it right!
