Hair Follicle Drug Testing - Phil Campbell, AL

What it is, How it works

Hair testing is now recognized as a robust method for detecting drug and alcohol consumption. Hair offers an extended timeline of alcohol and drug use by capturing biomarkers within the strands of growing hair. Obtaining hair near the scalp can reveal up to roughly a 3-month detection period for alcohol and drugs. Hair is easy to collect, challenging to tamper with, and straightforward to transport.

A sample measuring 1.5 inches with around 200 strands (approximately the thickness of a #2 pencil) closest to the scalp will offer 100mg of hair, which is the optimum sample for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, it is advisable to have 150mg of the specimen. We suggest using a jeweler’s scale to weigh the specimen. In the absence of scalp hair, a comparable amount of body hair is permissible. By head hair, we specifically mean scalp hair. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning pertains to the primary processing of a sample into a laboratory system. This step ensures the sample was appropriately sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and finalizes any extra data entry not supplied by an electronic chain of custody system.

Screening serves as an initial rapid check for drug misuse. Although it’s an economical means of excluding drug use in most samples, a positive screen requires confirmation for court admissibility. Samples that are presumptively positive in Screening must undergo a secondary confirmation.

For samples presumptively positive at the Screening phase, additional hair is extracted and prepped for Extraction. At this stage, drugs are retrieved from hair at a much lower concentration than other methodologies (e.g., urine or oral fluid), making hair drug screening the most complex methodology to conduct.

Verification of any positive screening result is carried out using GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo a wash before confirmation, as needed. The complete laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation criteria.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug usage for up to 90 days, unlike urine tests with shorter detection periods.
• Hard to tamper with: Cheating a hair drug test is nearly impossible, thus ensuring more accurate results.
• Provides a historical pattern: It reveals a trend of drug use over a longer duration, not just recent consumption.

Limitations:

• Cannot detect recent consumption: Drugs are typically detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests generally incur higher costs compared to other drug testing methods.
• Result variability: Factors like hair color and individual hair growth differences can influence drug metabolite concentration in hair.

Note: Commonly referred to as "hair follicle tests", the analysis is actually conducted on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
