Hair Follicle Drug Testing - Kemp Mill, MD

What it is, How it works

Hair testing is increasingly recognized as a robust method for identifying drug and alcohol usage. It captures a prolonged record of substances by embedding biomarkers within the hair strand as it grows. When collected near the scalp, hair provides a potential detection timeline for drugs and alcohol reaching up to about three months. The collection of hair is straightforward, hard to tamper with, and easy to transport.

Taking a 1.5-inch segment of roughly 200 hairs (approximately the size of a #2 pencil) closest to the scalp yields 100mg of hair, the optimum amount for screening and confirmation. To conduct EtG tests, add-ons, or tests exceeding 10 panels, 150mg of the sample is advisable. It's suggested to weigh the specimen using a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair may be collected. When discussing head hair, it strictly means scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).

Process Overview

Four fundamental steps are engaged in laboratory processing for a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning comprises the preliminary sample processing into a lab’s system, including verifying proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any leftover data entry not available through the electronic chain of custody.

Screening involves a rapid initial examination for drugs of abuse. Screening is a cost-effective method to exclude drug usage across most samples; however, a positive screen demands confirmation to be court-admissible. Samples found presumptively positive require secondary confirmation.

A sample testing positive during Screening necessitates extracting additional hair from the initial sample for the Extraction phase. This phase involves extracting drugs from hair at a lower concentration compared to other techniques (such as urine or oral fluid), making hair drug screening particularly challenging.

GC/MS, GC/MS/MS, or LC/MS/MS validation methods confirm any positive screen results. All presumptive positive samples are cleaned before confirmation if needed. The entire lab process from Accessioning to Confirmation undergoes review under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, whereas urine tests have a shorter detection span.
• Difficulty in evasion: Due to the challenging nature of cheating a hair drug test, the results tend to be more reliable.
• Historical usage data: It reveals a pattern of drug use over time, unlike tests that only detect recent use.

Limitations:

• Inability to detect recent use: It takes approximately 5-7 days for a drug to be detectable in hair.
• Expense: Hair drug tests usually cost more compared to other testing methods.
• Result variability: Variations in hair color and differences in individual hair growth might impact drug metabolite concentration in hair.

Note: Though frequently termed as "hair follicle tests", the actual test examines the hair strand, not the follicle beneath the scalp.
