Hair Follicle Drug Testing - Trail, OR

What it is, How it works

Hair testing is recognized as an effective method for identifying the use of drugs and alcohol. Through the integration of biomarkers within the strands of hair, a long-term overview of alcohol and other substance use is encased. When gathered close to the scalp, hair samples are useful for offering an evaluation window for alcohol and drugs extending up to three months. The collection process is straightforward, it is relatively hard to tamper with hair, and the shipping is uncomplicated.

A sample measuring 1.5 inches, which represents approximately 200 hair strands (akin to the diameter of a #2 pencil), when cut nearest to the scalp, will yield 100mg of hair, forming the ideal amount for both initial and confirmatory testing. For EtG, add-ons, or any tests exceeding 10 panels, gathering 150mg of the sample is advised. Using a jeweler’s scale for precision in weighing the specimen is suggested. In the absence of scalp hair, a comparable amount of body hair can be collected instead. The term head hair specifically pertains to scalp hair only, whereas body hair encompasses all other hair types such as facial and axillary hair.

Process Overview

The laboratory processing of a drug test is segmented into four critical phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the foundational processing of a specimen into the laboratory's framework. This process entails ensuring correct sealing and shipping of the sample, generating a random LAN (Laboratory Accessioning Number), and finalizing any additional data entry absent from an electronic chain of custody system.

Screening pertains to an initial provisional assessment for drug presence. Though a cost-efficient method to eliminate drug usage in most samples, any positive screening findings necessitate confirmation for court acceptance. Any results considered presumptively positive during Screening require the follow-up step of confirmation.

In any instance where Screening indicates a presumptive positive result, additional hair is obtained from the initial sample and prepped for Extraction. This involves extracting drugs at markedly lower concentrations compared to other techniques (like urine or saliva tests), establishing hair drug screening as the most challenging method to execute.

To verify any positive outcomes from Screening, Confirmation is performed employing GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Before confirmation, thorough washing of all presumptive positive samples is undertaken as required. The complete laboratory workflow, from Accessioning through Confirmation, is evaluated in alignment with both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can ascertain drug use for up to 90 days, versus the more limited detection period provided by urine tests.
• Difficulty to undermine: The challenge of tampering with a hair drug test bolsters the accuracy of the outcomes.
• Offers historical insight: This method can illustrate a drug use pattern over time, rather than just recent use.

Limitations:

• Incapability to identify new usage: It takes about 5-7 days for drugs to become detectable in hair samples.
• Cost factor: In general, hair drug tests are more costly than other drug testing techniques.
• Result variability: Factors such as hair color and individual variations in hair growth can influence the concentration of drug metabolites in hair samples.

Note: Despite the frequent misnomer "hair follicle tests", the actual test analyzes the strand of hair, not the follicle underlying the scalp.
