Hair Follicle Drug Testing - Lake Lindsey, FL

What it is, How it works

Hair analysis has become recognized as a robust method for identifying drug and alcohol consumption. Hair offers a prolonged record of alcohol and drug presence by encapsulating biomarkers within the fibers of the growing hair shaft. When obtained near the scalp, hair can offer up to an estimated 3-month detection timeframe for alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.

A 1.5-inch cut containing about 200 strands of hair (approximately the width of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal quantity for analysis and verification. For EtG, add-ons, and/or assays exceeding 10 panels, 150mg of the sample is advisable. It is suggested to measure the sample on a jeweler’s scale. If scalp hair is not present, an equivalent quantity of body hair can be taken. When referencing head hair, it pertains solely to scalp hair. Body hair signifies all other hair varieties (facial, axillary, etc.).

Process Overview

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

Accessioning entails the introductory handling of a sample into a laboratory’s system. This process involves confirming that the sample was sealed and dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data input not supplied by an electronic chain of custody system.

Screening involves a preliminary swift assessment for drugs of abuse. While Screening is a cost-efficient method to eliminate drug usage in the majority of instances, a positive screen must be validated to be acceptable in court. Any samples that show a presumptive positive in Screening necessitate a secondary verification.

Should a sample show a presumptive positive in the Screening phase, additional hair is extracted from the original specimen and readied for Extraction. In this phase, drugs are extracted from hair at a significantly lower concentration than in other techniques (e.g., urine or oral fluid), which makes hair drug analysis the most challenging methodology to implement.

Verification of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed prior to verification as required. The full laboratory procedure from Accessioning to Confirmation is monitored under both the CAP (College of American Pathologists) Hair designation and the authorization to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug assessments can recognize drug use for up to 90 days, unlike urine tests which have a shorter detection duration.
• Hard to manipulate: It is highly challenging to manipulate a hair drug test, ensuring more accurate results.
• Delivers historical data: It can depict a trend of drug consumption over an interval, not just recent intake.

Limitations:

• Cannot identify recent use: It requires roughly 5-7 days for substances to be traceable in hair.
• Cost: Hair drug analyses are typically more costly than other drug testing techniques.
• Variations in results: Elements such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: While often referred to as "hair follicle tests", the assay itself examines the hair strand rather than the hair follicle beneath the scalp
