Hair Follicle Drug Testing - Hillandale, MD

What it is, How it works

Hair testing is regarded as a highly effective method for evaluating drug and alcohol usage. Hair captures a long-term record of substances by embedding biomarkers within the fibers of the hair as it grows. When taken near the scalp, hair can offer up to a 3-month timeframe for identifying alcohol and drug use. Hair is easy to collect, challenging to tamper with, and straightforward to transport.

A 1.5-inch segment comprising roughly 200 hair strands (the diameter akin to a #2 pencil) closest to the scalp yields 100mg of hair, which is optimal for analysis and verification. For EtG additional assessments or tests beyond 10 panels, a 150mg specimen is advised. Using a jeweler’s scale for weighing the sample is recommended. Should scalp hair be absent, an equivalent amount of body hair may serve as a substitute. When mentioning head hair, it specifically pertains to scalp hair. In contrast, body hair denotes all other categories (facial, axillary, etc.).

Process Overview

The primary procedural phases in processing a drug test in a lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the preliminary processing of a sample within a lab's framework. This phase ensures the sample's proper sealing and shipment, assigns a unique LAN (Laboratory Accessioning Number), and concludes any extra data input that an electronic chain of custody system does not furnish.

Screening is the initial assessment to check for abusive drug substances. While cost-efficient for ruling out drug usage for most specimens, any positive outcomes during Screening must undergo confirmation for courtroom legitimacy. Any samples that show presumptive positives in Screening must be validated through secondary means.

When a sample appears positive during Screening, additional hair is extracted from the initial batch and readied for Extraction. This phase involves extracting drugs from the hair at notably low concentrations, distinguishing it from other methods (e.g., urine or oral fluid tests), which makes hair drug analysis the most challenging technique.

Confirmation of any positive results from screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples identified as presumptive positives undergo washing before confirmation, as necessary. The end-to-end lab procedure, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection time: Hair tests can track drug intake for up to 90 days, unlike urine tests which offer shorter detection periods.
• Hard to manipulate: Cheating a hair drug test is quite tough, which boosts result precision.
• Offers historical insights: It outlines drug usage trends over an extended duration, not just recent ingestion.

Limitations:

• Fails to identify recent usage: Drugs become detectable in hair after about 5-7 days.
• Pricing: Hair drug testing typically costs more than other testing methods.
• Result inconsistencies: Factors such as hair pigmentation and individual hair growth differences can impact drug metabolite concentration in hair.

Note: Despite being labeled as "hair follicle tests", the evaluation focuses on the hair strands and not the follicles beneath the scalp.
