Hair Follicle Drug Testing - Wye Mills, MD

What it is, How it works

Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. Hair captures a chronological archive of alcohol and drug presence by embedding biomarkers within its fibers during growth. Hair samples taken near the scalp can offer a detection period of up to roughly three months for alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and convenient for shipping.

A 1.5-inch segment made up of about 200 hair strands (approximately the thickness of a #2 pencil) from the scalp yields around 100mg, the optimal quantity for testing and confirmation. For EtG, additional assessments, and/or testing beyond 10 panels, 150mg of the hair sample is advised. It's best to measure the sample with a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair may be used. The term head hair specifically refers to scalp hair. Body hair encompasses all other hair types (such as facial and axillary).

Process Overview

The key stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a laboratory system. This step involves ensuring the sample's seal and shipment were intact, generating a random LAN (Laboratory Accessioning Number), and executing any extra data entry not covered by an electronic chain of custody system.

Screening consists of a preliminary, rapid assessment for abused drugs. Although Screening is a cost-effective method to largely exclude drug use, a positive result necessitates confirmation for legal acceptability. Any samples suspected to be positive in Screening mandate a subsequent confirmation.

For a sample flagged as presumptively positive in Screening, more hair is extracted from the initial sample for the Extraction stage. In this phase, drug extraction from hair occurs at notably lower concentrations compared to other techniques (such as urine or oral fluid), underscoring the complex nature of hair drug testing.

Confirmation of any positive screening results is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation as necessary. The complete laboratory procedure, from Accessioning to Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can uncover drug use up to 90 days, while urine tests have a more limited detection span.
• Tough to manipulate: Cheating a hair drug test is quite challenging, enhancing result accuracy.
• Supplies historical context: It offers a chronicled pattern of drug consumption over time, not merely recent usage.

Limitations:

• Does not capture recent use: Detection of drugs in hair typically requires 5-7 days.
• Expense: Hair drug testing usually costs more than other drug testing methods.
• Result variations: Elements like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: While commonly called "hair follicle tests", this test examines the hair strand rather than the follicle under the scalp

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Wye Mills, MD
The advantages of hair follicle drug testing over traditional urine tests are significant, especially in Wye Mills, MD. Hair tests offer a superior detection window, capturing drug use up to 90 days prior, unlike urine tests that lead to shorter windows of 3 to 4 days.
