Hair Follicle Drug Testing - East Rockwood, MI

What it is, How it works

Hair analysis is regarded as a significant method for detecting drug and alcohol consumption. Hair offers an extended timeline of alcohol and drug use by embedding biomarkers within the hair's growing fibers. When cut near the scalp, hair can reveal drug and alcohol usage for up to about three months. Hair is straightforward to collect, relatively hard to tamper with, and simple to transport.

Acquiring a 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil) nearest the scalp will produce 100mg of hair, which is optimal for both screening and validation. For EtG tests, additional screenings, or panels exceeding 10, 150mg of the sample is advised. Utilizing a jeweler's scale for weighing the sample is suggested. If scalp hair is inaccessible, a similar quantity of body hair can be gathered. "Head hair" specifically refers to scalp hair, whereas "body hair" indicates other types including facial and axillary hair.

Process Overview

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

Accessioning comprises the initial steps of integrating a sample into a laboratory's workflow. This process includes ensuring the sample was appropriately sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and finishing any extra data entry that an electronic chain of custody system may not cover.

Screening is a preliminary rapid assessment for drugs of abuse. While Screening is an economical method to eliminate drug usage in most samples, a confirmed positive result is necessary for court acceptability. Any samples showing presumptive positivity during Screening undergo secondary confirmation.

If a sample is found presumptively positive at the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. In this step, the extraction of drugs from hair occurs at much lower concentrations compared to other techniques (i.e., urine or oral fluid), explaining the complexity of hair drug screening.

Confirmation of any positive screen result employs techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are washed before confirmation as required. The thorough lab process from Accessioning through Confirmation is evaluated under both the CAP (College of American Pathologists) Hair classification and accreditation aligned with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug assessments can identify drug use for up to 90 days, unlike urine tests which cover shorter periods.
• Challenges in manipulation: It is notably difficult to alter results in hair drug testing, leading to increased accuracy.
• Offers historical insights: It provides patterns of drug use over a span, not merely recent usage.

Limitations:

• Unable to detect immediate use: It typically takes around 5-7 days for drugs to manifest in hair.
• Expense: Hair drug assessments often incur higher costs than other drug testing techniques.
• Inconsistencies in results: Variables such as hair color and personal differences in hair growth may influence drug metabolite levels in hair.

Note: Despite being frequently called "hair follicle tests", these tests analyze the hair strand, not the follicle under the scalp.

Why Hair Follicle Testing Beats Urine Testing
