Hair Follicle Drug Testing - Chesterfield, MO

What it is, How it works

Hair testing is recognized as an effective means for identifying drug and alcohol consumption. By embedding biomarkers in the hair's growing strand fibers, hair offers an extended timeline of drug and alcohol activity. When hair is sampled near the scalp, it can reveal alcohol and drug usage over a period of up to three months. Collecting hair is straightforward, tampering is less feasible, and shipment is uncomplicated.

A 1.5-inch section consisting of around 200 hair strands (approximating the size of a #2 pencil) nearest to the scalp delivers 100mg of hair, which is optimal for both screening and confirmation. For EtG, add-ons, or panel tests exceeding 10, 150mg of the sample is suggested. Using a jeweler’s scale for specimen measurement is advisable. Should scalp hair be unavailable, an equivalent amount of body hair is acceptable. The mention of head hair pertains solely to scalp hair, whereas body hair encompasses all other types like facial and axillary hair.

Process Overview

The laboratory process for a drug test encompasses four principal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the introductory phase where a sample is entered into a laboratory’s system. This step includes checking that the sample was correctly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and finishing any supplemental data entry absent from an electronic chain of custody system.

Screening performs an initial, rapid evaluation for drugs of abuse. While this method is an economical strategy to exclude drug use in most samples, a positive screening must be confirmed to be permissible in legal settings. Presumptive positives found in Screening necessitate secondary confirmation.

For a sample showing presumptive positivity in Screening, additional hair is extracted from the original specimen and prepped for Extraction. During this phase, the concentration of drugs drawn from hair is considerably lower compared to other methods (e.g., urine or oral fluid), making hair drug screening a notably challenging technique.

Confirmation of any positive screen is achieved through GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All presumptive positive samples undergo washing before confirmation as required. The entire lab procedure, from Accessioning to Confirmation, is subject to evaluation under both the CAP (College of American Pathologists) Hair certification and accreditation to the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for as long as 90 days, unlike urine tests which have a shorter detection period.
• Hard to manipulate: Cheating a hair drug test is extremely challenging, ensuring that results are more reliable.
• Historical insight: It offers a timeline of drug use that covers more than just recent consumption.

Limitations:

• Can't identify recent consumption: Drugs typically become detectable in hair only after 5-7 days.
• Expense: Hair drug testing generally incurs higher costs compared to other testing methods.
• Result variability: Elements such as hair color and distinct differences in hair growth can influence drug metabolite levels in hair.

Note: Often labeled as "hair follicle tests," these analyses actually examine the hair strand, not the beneath-the-scalp hair follicle.
