Hair Follicle Drug Testing - Brent, FL

What it is, How it works

Hair analysis is recognized as an effective means for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of the hair strand as it grows, hair offers a prolonged historical record of substance use. Sampling hair near the scalp can yield an approximate detection timeframe of three months for alcohol and drugs. Hair collection is straightforward, relatively hard to tamper with, and easily transportable.

A hair sample of 1.5 inches, around 200 strands (comparable to a #2 pencil), closest to the scalp provides 100mg, which is the optimal amount for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advised. Utilizing a jeweler’s scale is recommended for weighing the specimen. Should scalp hair be unavailable, an equivalent quantity of body hair can be collected. References to head hair pertain exclusively to scalp hair, whereas body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails entering a sample into a laboratory’s system initially. This step involves confirming the sample’s seal and proper shipment, allocating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent from an electronic chain of custody system.

Screening includes a preliminary assessment for drugs of abuse. Although Screening is a cost-efficient method to exclude drug use in numerous samples, a positive screen must undergo confirmation to be valid in court. Samples that preliminarily test positive in Screening necessitate secondary confirmation.

Should a sample test presumptively positive during the Screening phase, additional hair is extracted from the original specimen for Extraction. In this phase, drug extraction from hair occurs at a significantly lower concentration than other methodologies (e.g., urine or oral fluid), making hair drug testing the most challenging methodology to execute.

Confirmation of any positive screening result is done via GC/MS, GC/MS/MS, or LC/MS/MS. Any samples showing presumptive positivity are cleansed before confirmation as required. The complete laboratory procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use up to 90 days, whereas urine tests have a more limited detection timeframe.
• Challenge to falsify: Hair drug tests are difficult to cheat, ensuring more reliable results.
• Shows historical usage patterns: It can illustrate a timeline of drug use, not only recent consumption.

Limitations:

• Inability to detect recent use: Detection of drugs in hair takes roughly 5-7 days post-consumption.
• Expense: Hair drug testing tends to be pricier than other drug testing techniques.
• Result variability: Variations such as hair color and personal differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: While commonly termed "hair follicle tests," the test examines the hair strand, not the hair follicle located beneath the scalp.
