Hair Follicle Drug Testing - Reston, VA

What it is, How it works

Hair testing is increasingly recognized as an effective means to detect drug and alcohol use. It offers an extended history by capturing biomarkers within the growing hair fibers. When cut nearest the scalp, the hair provides around a three-month detection timeframe for alcohol and drugs. The collection process is straightforward, challenging to tamper with, and convenient for transportation.

A sample measuring 1.5 inches and consisting of about 200 hair strands (similar in size to a #2 pencil) nearest the scalp yields around 100mg, the perfect quantity for both screening and verification. For EtG, additional analyses, and/or tests exceeding 10 panels, a specimen amounting to 150mg is advised. It's suggested to weigh the sample using a jeweler’s scale. If scalp hair is absent, a similar quantity of body hair might be used. "Head hair" specifically denotes scalp hair, while "body hair" encompasses all other types (face, armpits, etc.).

Process Overview

The primary stages in processing a drug test result within a lab comprise Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary processing of a specimen within a lab’s system. This step ensures the sample’s sealing and proper shipment, assigns a random LAN (Laboratory Accessioning Number), and completes remaining data entry not covered by an electronic chain of custody.

Screening is a quick preliminary check for substance abuse. It's a cost-efficient method to identify drug absence in most samples, but any positive screen must be verified for court-acceptable evidence. Any samples preliminarily positive in Screening require further confirmation.

If a sample is presumed positive during Screening, additional hair is extracted from the initial sample for Extraction. This stage involves extracting drugs from hair at a substantially lower concentration than other methods (e.g., urine or saliva), highlighting the complexity of hair drug testing.

Confirmation for positive screens is done using GC/MS, GC/MS/MS, or LC/MS/MS. All preliminary positive samples undergo washing pre-confirmation as necessary. The whole lab process from Accessioning to Confirmation is evaluated under both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify substance use for a maximum of 90 days, unlike urine tests that have a shorter period.
• Resistance to tampering: Cheating a hair drug test is highly challenging, ensuring more reliable results.
• Historic usage insight: It delivers a usage pattern over time, not just recent consumption.

Limitations:

• Inability to detect recent consumption: Drugs become detectable in hair after about 5-7 days.
• Expense: Hair drug testing generally incurs higher costs compared to other methods.
• Result variability: Aspects like hair color and individual growth differences can impact drug metabolite concentration in hair.

Note: Although often termed as "hair follicle tests", the analysis is performed on the hair strand itself, not the follicle beneath the scalp
