Hair Follicle Drug Testing - Savage, MD

What it is, How it works

Hair testing is recognized as a robust method for detecting drug and alcohol use. Hair provides an extended timeline of alcohol and drug history by capturing biomarkers within the fibers of the growing strand. When hair is sampled near the scalp, it offers approximately a three-month detection period for alcohol and drugs. Collection is straightforward, alteration is challenging, and shipping is convenient.

A 1.5-inch sample consisting of around 200 hairs (approximately the size of a #2 pencil) nearest the scalp yields 100mg, the ideal amount for analysis and confirmation. For EtG, additional testing, or tests exceeding 10 panels, 150mg of the sample is preferred. Measuring the sample with a jeweler’s scale is recommended. If scalp hair isn't available, an equivalent quantity of body hair may be taken. Head hair refers solely to scalp hair, while body hair encompasses all other hair types (e.g., facial, axillary).

Process Overview

The four primary phases in the laboratory processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase where a sample is logged into the laboratory system. This process includes verifying the sample's seal and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any remaining data input not managed by an electronic chain of custody system.

Screening offers a preliminary check for drugs of abuse. While Screening provides a cost-effective means to rule out drug use for most samples, a positive result requires confirmation for court admissibility. Samples that are presumptively positive in Screening necessitate a secondary confirmation.

When a sample appears positive during Screening, additional hair is taken from the original specimen for Extraction. During this phase, drugs are extracted from hair at lower concentrations than in other methodologies (such as urine or oral fluid), making hair drug screening particularly challenging to perform.

Confirmation of any positive screen result is completed through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are cleansed as needed. The entire laboratory process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection period: Hair drug tests detect drug use for up to 90 days, whereas urine tests have a briefer detection span.
• Difficult to deceive: Cheating on a hair drug test is quite challenging, which enhances result accuracy.
• Offers historical insight: It establishes a pattern of drug use over time, not just recent activities.

Limitations:

• Cannot detect current use: Drugs typically require 5-7 days to be traceable in hair.
• Expense: Hair drug tests generally cost more than alternative testing methods.
• Result variations: Factors like hair color and individual differences in hair growth can influence drug metabolite levels in hair.

Note: Although referred to as "hair follicle tests", the analysis pertains to the hair strand and not the follicle beneath the scalp.
