Hair Follicle Drug Testing - Southeast Pontotoc, OK

What it is, How it works

Hair testing is recognized as an influential method for identifying drug and alcohol consumption. Hair accumulates a history of alcohol and drug use by trapping biomarkers within the fibers of the growing hair shaft. When obtained near the scalp, hair can offer a detection window extending up to roughly three months for both alcohol and drugs. Collecting hair is straightforward, somewhat resistant to tampering, and convenient to transport.

A 1.5-inch sample consisting of approximately 200 hair strands (comparable to the thickness of a #2 pencil) closest to the scalp will provide 100mg of hair, which is the optimal sample size for screening and validation. For EtG, add-ons, and/or tests exceeding 10 panels, a specimen weight of 150mg is suggested. Utilizing a jeweler’s scale is advisable for weighing the sample. If scalp hair is not available, an equivalent quantity of body hair may be collected. The term head hair specifically refers to scalp hair. Body hair refers to all other hair categories (facial, axillary, etc.).

Process Overview

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

During Accessioning, the sample undergoes preliminary processing into the laboratory’s system. This process involves verifying the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data not included within an electronic chain of custody system.

Screening entails an initial rapid test for substances of abuse. Screening serves as a cost-effective measure to exclude drug use for the majority of samples, however, a positive screen must be corroborated to be permissible in legal settings. Any samples flagging as presumptively positive during Screening require a follow-up confirmation.

Should a sample turn out presumptively positive during the Screening phase, additional hair is extracted from the original specimen and readied for Extraction. At this stage, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting why hair drug screening is considered challenging to perform.

Confirmation for any positive screening result is undertaken through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Any samples showing presumptive positivity are cleansed prior to confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation undergoes rigorous review under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug consumption for up to 90 days, whereas urine tests present a shorter detection period.
• Increased difficulty in tampering: It is highly challenging to manipulate the outcome of a hair drug test, thus ensuring more precise results.
• Yield historical data: It provides a pattern of drug consumption over a span of time, rather than merely indicating recent usage.

Limitations:

• Inability to detect recent usage: It takes roughly 5-7 days for drugs to become detectable in hair.
• Expense: Generally, hair drug tests incur more cost compared to alternative drug testing methods.
• Result variability: Variables such as hair color and individual hair growth differences can influence drug metabolite concentration within the hair.

Note: Although often termed as "hair follicle tests", the actual test examines the hair strand and not the follicle beneath the scalp.
