Hair Follicle Drug Testing - Three Way, TN

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair offers an extended timeline of drug and alcohol presence by embedding biomarkers within the strands as they grow. When taken directly from the scalp, hair can provide an approximate three-month period of detectability for various substances. The sample collection process is straightforward, resistant to tampering, and simple to transport.

A sample measuring 1.5 inches, consisting of nearly 200 hair strands (approximately the diameter of a #2 pencil), near the scalp yields 100mg of hair, which is the optimal quantity for both screening and verification. For tests like EtG, add-ons, or those exceeding 10 panels, a 150mg sample is advised. Using a jeweler’s scale for weighing the specimen is suggested. If scalp hair cannot be obtained, an equivalent amount of body hair may be used. 'Head hair' specifically addresses scalp hair, while 'body hair' encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory procedure for drug test evaluation comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary phase of integrating a sample into the laboratory’s framework. It involves ensuring the sample's seal and shipment were handled correctly, allocating a random LAN (Laboratory Accessioning Number), and finalizing any remaining data entry not covered by an electronic chain of custody.

Screening serves as an initial, rapid assessment for prohibited substances. Although Screening offers a cost-efficient method to exclude drug use in most samples, a positive result requires confirmation to hold up in legal proceedings. Any sample with a preliminary positive outcome in Screening necessitates a subsequent verification.

If the Screening stage yields a presumptive positive, additional hair is sourced from the initial sample for the Extraction phase. Here, drugs are isolated from hair at much lower concentrations compared to other methods, such as urine or oral fluid, thus making hair drug tests particularly challenging to perform.

Positive screening outcomes are confirmed using methodologies like GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, any samples with presumptive positives are washed if needed. From Accessioning to Confirmation, the complete laboratory procedure adheres to the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can identify drug use for up to 90 days, surpassing the shorter detection timeframe of urine tests.
• Resistance to tampering: Hair tests are notoriously hard to cheat, enhancing result accuracy.
• Historical usage insight: Offers a timeline of substance use patterns, not just recent consumption.

Limitations:

• Inability to detect recent consumption: It requires about 5-7 days for drugs to register in hair.
• Price: Hair drug testing is typically costlier than alternative testing methods.
• Result variability: Drug metabolite concentrations can be influenced by factors like hair color and individual growth differences.

Note: Commonly named "hair follicle tests," the actual analysis is performed on the hair shaft and not on the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Testing Prevails
