Chapter 2 Specimens for Drugs-of-Abuse Testing

  title={Chapter 2 Specimens for Drugs-of-Abuse Testing},
  author={Leo J. Kadehjian},
A wide variety of body fluid specimens have been utilized for analysis for the presence of drugs of abuse. Urine has been and remains the most widely used body fluid specimen for routine testing for drugs of abuse, but several alternative specimens are establishing their place as suitable for drug testing. Hair, sweat, and oral fluid have reached a sufficient level of scientific credibility to be considered for use in the federally regulated workplace drug-testing programs. Each specimen… 



An evaluation of rapid point-of-collection oral fluid drug-testing devices.

Overall, the performance of these rapid POC oral fluid drug-testing devices was quite variable, and most devices performed well for the detection of methamphetamine and opiates, but all performed poorly for the Detection of cannabinoids.

Alternative specimens for workplace drug testing.

The present focus is on oral fluid (saliva), hair, and sweat, which will become routine in all areas of forensic toxicology in future years.

Oral fluid testing for drugs of abuse: positive prevalence rates by Intercept immunoassay screening and GC-MS-MS confirmation and suggested cutoff concentrations.

Comparison of oral fluid drug concentrations to SAMHSA-recommended cutoff concentrations in Draft Guidelines indicated that adoption of the screening and confirmation cutoff concentrations of Draft Guidelines #3 would produce the most consistent reporting results for all drug classes except amphetamines.

A Comparison of Saliva Testing to Urinalysis in an Arrestee Population

Analysis of saliva test results suggested that saliva may have some advantages over urine because of the ease of collection, invulnerability to adulteration, and minimal personal invasiveness, and a more comprehensive study to evaluate the efficacy of saliva testing in field research may be warranted.

Comparison of daily urine, sweat, and skin swabs among cocaine users.

Interlaboratory studies on the analysis of hair for drugs of abuse: results from the fourth exercise.

Fourteen laboratories interested in the analysis of human hair for drugs of abuse participated in a fourth interlaboratory study to determine how well drugs could be detected and quantitated in hair.

Analysis of Ethanol in Saliva

Testing of saliva for alcohol can serve both of the goals of on-site testing and the use of specimens alternative to the primary specimen for nonethanol drugs, urine, and thePrimary specimen for alcohol1, breath.
