Hair Follicle Drug Testing - Mallard, IA

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair can encapsulate a continuous record of alcohol and drug use by capturing biomarkers within the fibers of the growing strand. When collected near the scalp, hair can reveal a detection period for alcohol and other drugs of up to roughly three months. Hair collection is straightforward, somewhat tamper-resistant, and easily transportable.

A 1.5-inch section of roughly 200 hair strands, approximately equal in thickness to a #2 pencil, taken nearest to the scalp will yield 100mg of hair, the optimal sample size for screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a specimen of 150mg is suggested. We advocate measuring the specimen on a jeweler’s scale. If scalp hair isn’t available, a comparable amount of body hair may be used. When mentioning head hair, we specifically mean scalp hair. Body hair refers to any other hair types (such as facial, axillary, etc.).

Process Overview

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

Accessioning refers to the initial entry of a sample into a lab’s database. This process ensures the sample was sealed and dispatched correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data entry not covered by an electronic chain of custody system.

Screening involves a preliminary assessment for drugs of abuse. Though Screening provides a cost-efficient method to eliminate drug use in most samples, a positive result needs confirmation to be legally admissible. Hence, any samples that test presumptively positive during Screening require further confirmation.

Should a sample show a presumptive positive in the Screening stage, additional hair is extracted from the initial sample and readied for Extraction. During this phase, drugs are isolated from hair at concentrations significantly lower than other methods (like urine or oral fluids), making hair drug screening the most intricate methodology to execute.

Confirmation of any positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation, as needed. The entire lab process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair categorization and the accreditation per ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use over an approximately 90-day period, unlike urine tests which have a shorter detection timeframe.
• Hard to alter: Hair drug tests are challenging to manipulate, thus enhancing the accuracy of results.
• Chronological data: It delivers a drug use pattern over time, not just recent usage.

Limitations:

• Cannot identify recent use: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug tests typically cost more than other testing methods.
• Result variations: Factors like hair color and individual growth variations can influence the drug metabolite levels in hair.

Note: Although often termed "hair follicle tests", the actual test analyzes the hair strand rather than the follicle beneath the scalp
