Hair Follicle Drug Testing - K. I. Sawyer, MI

What it is, How it works

Hair analysis is increasingly recognized as an effective means of identifying drug and alcohol consumption. Hair serves as a long-term record of alcohol and other substances by trapping biomarkers within the fibers of the growing strand. When taken close to the scalp, this hair sample can offer a detection period of up to around three months for alcohol and various drugs. Collecting hair is easy, it is relatively resistant to tampering, and it is simple to ship.

A 1.5-inch segment containing roughly 200 strands of hair (close to the thickness of a #2 pencil) nearest the scalp supplies 100mg of hair, which is the optimal amount for screening and confirmation. For EtG tests, add-ons, and/or panels beyond 10, it is advised to use 150mg of the sample. We recommend weighing the sample using a jeweler’s scale. Should scalp hair be unavailable, an equivalent amount of body hair may be used. When mentioning head hair, we specifically mean scalp hair. Body hair covers all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result encompasses four major stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the introductory processing of a sample into the laboratory's system. This process checks that the sample was sealed and delivered correctly, assigns a unique LAN (Laboratory Accessioning Number), and completes any remaining data entry not handled by an electronic chain of custody system.

Screening involves an initial rapid inspection for substances of misuse. Though Screening is an economical approach for dismissing drug usage in most samples, a positive screening result must be confirmed to be admissible in judicial proceedings. Samples that appear positive in Screening necessitate further confirmation.

If Screening suggests a positive result, additional hair is extracted from the original sample to prepare for Extraction. In this phase, drugs are extracted from hair at a concentration much lower than in alternative methodologies (for instance, urine or oral fluid), making hair drug screening a complex methodology to execute.

Confirmation of any positive screening outcome is conducted using GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples presumed to be positive are washed before confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests have the ability to identify drug usage up to 90 days prior, in contrast to urine tests which have a more limited detection window.
• Hard to deceive: Cheating on a hair drug test is notably challenging, enhancing the accuracy of results.
• Offers historical insight: It has the capability to demonstrate a pattern of drug use over time, not just recent consumption.

Limitations:

• Inability to detect recent use: Drugs take approximately 5-7 days before they become detectable in hair.
• Expense: Hair drug tests typically come at a higher cost compared to other drug testing approaches.
• Result variability: Factors such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in hair.

Note: Although often labeled as "hair follicle tests", the analysis itself is conducted on the hair strand rather than the follicle beneath the scalp.
