Hair Follicle Drug Testing - Stiles, IA

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged record of substance use by embedding biomarkers within the fibers of the growing strand. Collected near the scalp, it offers an approximately 3-month detection period for substances. Collecting hair is straightforward, challenging to tamper with, and convenient to transport.

A 1.5-inch portion of roughly 200 hair strands (about the thickness of a #2 pencil) nearest to the scalp yields 100mg, the optimal amount for screening and verification. For EtG, additional tests, and tests exceeding 10 panels, a 150mg sample is recommended. We advise verifying the specimen's weight using a jeweler's scale. If scalp hair isn't available, an equivalent amount of body hair can be used. When mentioning head hair, it refers exclusively to scalp hair, while body hair pertains to all other hair types (facial, axillary, etc.).

Procedure Outline

The core stages in processing a laboratory drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning comprises of the preliminary handling of a specimen in the lab’s system, which involves verifying the sample's proper sealing and shipment, allocating a random LAN (Laboratory Accessioning Number), and finishing any extra data entry not available via an electronic chain of custody system.

Screening serves as a rapid check for drugs of abuse. It's an economical way to identify drug presence in most samples, but a confirmed positive result is essential for legal validity. Samples with presumption of positivity from Screening must undergo additional confirmation.

Should a sample indicate potential positivity in Screening, more hair is extracted from the initial sample for the Extraction phase. Here, drugs are extracted from the hair at a much lower rate than other methods (e.g., urine or oral fluids), highlighting the complexity of hair drug testing.

Confirming a positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation if required. The entire lab process from Accessioning through Confirmation is evaluated under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Benefits of hair drug tests:

• Extended detection timeframe: Hair drug tests can detect use for up to 90 days, unlike urine tests which have a shorter detection timeframe.
• Challenging to adulterate: Cheating a hair drug test is very difficult, resulting in more reliable outcomes.
• Offers historical insight: It demonstrates a pattern of substance use over a span of time, not just recent use.

Drawbacks:

• Inability to detect recent use: Drugs become detectable in hair around 5-7 days following use.
• Expense: Hair drug tests typically cost more than other drug testing techniques.
• Result variations: Variance factors like hair color and individual hair growth differences can alter drug metabolite concentrations in hair.

Note: Although often termed "hair follicle tests", the analysis targets the hair strand itself, not the follicle beneath the scalp.
