Hair Follicle Drug Testing - Troy Grove, IL

What it is, How it works

Hair testing has emerged as a formidable instrument for identifying drug and alcohol usage. It serves as a repository for a long-term history of substance use by embedding biomarkers within the fibers of the growing hair. When collected near the scalp, hair affords an approximate 3-month detection period for both alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and facile to transport.

Obtaining a 1.5-inch segment of around 200 hair strands (akin to the thickness of a #2 pencil) nearest the scalp yields 100mg of hair, which is the optimal amount for both screening and confirmation. For tests exceeding 10 panels, EtG, or add-ons, it is advised to gather 150mg of the sample. We suggest using a jeweler’s scale for specimen weighing. Should scalp hair be unavailable, an equivalent amount of body hair is acceptable. References to head hair specifically denote scalp hair. Body hair encompasses all other hair types, such as facial and axillary hair.

Process Overview

The laboratory processes for a drug test result entail four primary steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes initial processing into the laboratory’s system. This step includes ensuring proper sealing and shipping of the sample, allocating a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry that is not automated by an electronic chain of custody system.

Screening involves an initial expedited assessment for substance abuse. Although Screening serves as an economical method to exclude drug use in most cases, a positive result requires confirmation before it becomes legally valid. Any samples yielding a presumptive positive result at the Screening stage necessitate secondary confirmation.

Presumptively positive samples in Screening prompt additional hair extraction from the initial specimen for the Extraction phase. In this phase, drugs are isolated from hair at considerably lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing the most intricate methodology to perform.

Confirming any positive screening result utilizes GC/MS, GC/MS/MS, or LC/MS/MS technologies. All presumptive positive samples are suitably washed before confirmation if necessary. The comprehensive laboratory procedure from Accessioning through to Confirmation is evaluated under the guidance of both the CAP (College of American Pathologists) for Hair accreditation and ISO/IEC 17025 standards adherence.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can reveal drug consumption over a 90-day span, unlike urine tests which have a more confined detection interval.
• Difficulty to cheat: The likelihood of cheating a hair drug test is minimal, thereby enhancing result accuracy.
• Provides historical data: It maps out a pattern of drug use over time rather than indicating recent use alone.

Limitations:

• Cannot detect recent use: It generally takes about 5-7 days for any drug consumption to be traceable in hair.
• Cost: Hair drug tests typically incur higher expenses than alternative testing methodologies.
• Variations in results: Factors like hair color and individual differences in hair growth can influence the concentration of drug metabolites within the hair.

Note: While frequently termed "hair follicle tests", the analysis is conducted on the hair shaft itself, not on the follicle beneath the scalp.
