Hair Follicle Drug Testing - Wyndmoor, PA

What it is, How it works

Hair testing is increasingly regarded as a crucial method for identifying drug and alcohol consumption. Hair serves as an extended history of alcohol and drug use by embedding biomarkers within the fibers of the developing hair strand. When collected near the scalp, hair specimens offer nearly a three-month detection window for alcohol and drugs. Hair is easy to collect, relatively tamper-resistant, and convenient to transport.

A 1.5-inch sample comprising roughly 200 hair strands (about the size of a #2 pencil) close to the scalp should weigh approximately 100mg, which is the optimal amount for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a specimen weighing 150mg is advisable. It is recommended to weigh the specimen using a jeweler’s scale. If scalp hair isn't available, an equivalent quantity of body hair may be used. References to head hair pertain solely to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

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

During Accessioning, a sample is initially processed into a laboratory's system. This step ensures the sample is sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data entry missing from an electronic chain of custody system.

Screening involves an initial rapid assessment for substances of abuse. Although Screening is cost-efficient for eliminating drug use in the majority of cases, a positive screen must be confirmed for court admissibility. Samples perceived as presumptively positive during Screening require subsequent confirmation.

If a sample yields a presumptively positive result in the Screening phase, more hair is extracted from the original specimen for preparation in the Extraction stage. In this stage, drugs are extracted from hair at significantly lower concentrations than those found in alternate methods (e.g., urine or oral fluid), which illustrates the complexity of conducting hair drug screening.

Confirmation of any positive screening outcome is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample is cleansed before confirmation as necessary. The entire laboratory sequence from Accessioning to Confirmation undergoes evaluation under the CAP (College of American Pathologists) Hair classification and conforms to ISO / IEC 17025 standards.

Strengths of hair drug testing:

• Long detection period: Hair drug tests can identify drug use up to 90 days, unlike urine tests that have shorter detection spans.
• Resistance to cheating: Cheating a hair drug test is notably difficult, enhancing result accuracy.
• Historical insight: It reveals a timeline of drug usage, not merely recent consumption.

Drawbacks:

• Cannot identify recent consumption: It takes roughly 5-7 days for drugs to be detectable in hair.
• Expense: Hair drug tests are typically costlier than other drug testing techniques.
• Variability in outcomes: Factors like hair color and individual hair growth variations can influence drug metabolite concentration in hair.

Note: While commonly termed as "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
