Hair Follicle Drug Testing - Lealman, FL

What it is, How it works

Hair analysis has gained recognition as an effective method for detecting substance use. Hair captures long-term evidence of alcohol and illicit substances by embedding biomarkers within the fibers of the hair shaft. When taken near the scalp, hair can offer a detection range of up to about 90 days for alcohol and drugs. The collection process for hair is straightforward, moderately hard to tamper with, and convenient for transport.

A sample length of 1.5 inches containing roughly 200 hair strands (approximately the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal amount for both initial screening and further verification. For tests like EtG, add-ons, and those exceeding 10 panels, a sample weighing 150mg is advisable. It is suggested to measure the specimen's weight using a jeweler's scale. In instances where head hair is not obtainable, an equivalent quantity of body hair may be used. Referring to head hair typically indicates scalp hair alone. Body hair encompasses all other types, including facial and axillary.

Process Overview

The four crucial stages in the lab analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step where the sample is processed into a lab's database. This stage ensures the sample's proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and completes any remaining data entries not included in an electronic chain of custody record.

Screening is an initial, rapid assessment for drugs of abuse. Though Screening offers a cost-efficient method to potentially exclude drug use for most samples, a confirmed positive finding is necessary for legal admittance. Samples presumptively positive during Screening require secondary validation.

Should a sample be presumptively positive in the Screening phase, additional hair is extracted from the original specimen and prepped for Extraction. Drugs are isolated from hair at a lower concentration than in alternative methods (such as urine or oral fluid), which positions hair drug analysis as the most challenging methodology to execute.

The verification of any positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to Confirmation, all presumptive positive samples undergo washing if needed. Every step of the laboratory process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair standards and compliance with ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug consumption for up to 90 days, whereas urine tests have a more limited detection period.
• Resistance to manipulation: It's highly challenging to falsify a hair drug test, enhancing result accuracy.
• Chronological data provision: It can document a timeline of drug use rather than just recent activity.

Limitations:

• Inability to identify recent use: It takes around 5-7 days for drugs to emerge in hair.
• Expense: Hair drug tests typically incur higher costs than other testing techniques.
• Result variability: Factors such as hair color and individual discrepancies in growth rate can influence drug metabolite concentrations in the hair.

Note: Although often termed "hair follicle tests", these analyses actually evaluate the hair shaft, not the follicle beneath the scalp.
