Hair Follicle Drug Testing - Pinckney, MI

What it is, How it works

Hair analysis has emerged as an effective method for detecting drug and alcohol consumption. By capturing biomarkers in the fibers of the growing hair strand, hair provides a comprehensive long-term record of alcohol and drug use. When collected from near the scalp, hair offers a detection window for alcohol and drugs of up to roughly 3 months. Hair collection is easy to perform, challenging to tamper with, and straightforward to transport.

A 1.5-inch segment comprising around 200 hair strands (approximately the diameter of a #2 pencil) sourced closest to the scalp provides 100mg of hair, which is the optimal amount needed for screening and confirmation. For EtG, supplementary tests, and/or tests exceeding a 10-panel range, 150mg of the sample is suggested. It is advisable to weigh the sample on a jeweler’s scale. If scalp hair cannot be obtained, an equivalent volume of body hair may be utilized. When referencing head hair, it specifically pertains to scalp hair, whereas body hair includes all other types (such as facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is initially processed into the laboratory’s system. This step includes verifying that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entries that are not covered by an electronic chain of custody system.

Screening involves a preliminary examination for drug presence. While Screening is a cost-efficient approach for eliminating drug use suspicions in the majority of samples, a positive screen must be validated for legal admissibility. Samples with presumptively positive results in Screening require further confirmation.

If results are presumptively positive during Screening, additional hair is extracted from the initial sample and prepared for Extraction. This stage involves extracting drugs from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), highlighting why hair drug testing is the most complex methodology to execute.

The Confirmation of any positive result from Screening is conducted via GC/MS, GC/MS/MS or LC/MS/MS. Samples identified as presumptively positive are washed prior to confirmation as needed. The entire laboratory workflow from Accessioning to Confirmation is carefully reviewed under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, unlike urine tests, which have a shorter detection period.
• Resistance to tampering: Hair drug testing is difficult to manipulate, enhancing result accuracy.
• Historical usage data: It offers patterns of drug usage over time, rather than solely recent consumption.

Limitations:

• Inability to detect recent usage: It takes around 5-7 days for drugs to appear in the hair.
• Expense: Hair drug tests are usually more costly compared to other drug testing techniques.
• Result variability: Factors like hair color and individual hair growth differences can impact drug metabolite concentration in hair.

Note: Although often termed "hair follicle tests", the analysis is conducted on the hair strand and not the follicle beneath the scalp
