Hair Follicle Drug Testing - Tilden, WI

What it is, How it works

Hair tests are regarded as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of substances by holding onto biomarkers within the strands as they grow. When hair is snipped close to the scalp, it can offer a detection period of up to about three months for various substances. Hair is straightforward to gather, fairly challenging to tamper with, and convenient to transport.

A recommended sample consists of a 1.5-inch portion, roughly 200 strands (comparable to the thickness of a #2 pencil), nearest to the scalp, yielding 100mg, which is ideal for both initial testing and confirmation. For EtG, additional tests, and/or screenings exceeding 10 panels, a 150mg sample is advisable. Using a jeweler’s scale to weigh the specimen is suggested. Should scalp hair be unavailable, an equivalent amount of body hair can be used. When discussing head hair, we specifically mean scalp hair. Body hair includes all other varieties (facial, axillary, etc.).

Process Overview

The lab handling of drug test results involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step where a sample is integrated into the lab's system, which involves ensuring the sample was sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any pending data entry absent from an electronic chain of custody system.

Screening evaluates the sample for common drugs. Though this method is economical for ruling out substance use in most samples, any results indicating positivity require subsequent verification to be acceptable in legal proceedings. Samples that test preliminarily positive during Screening must undergo secondary confirmation.

Should a sample register positive during the Screening phase, additional hair is retrieved from the initial batch and readied for Extraction. At this juncture, substances are extracted from hair at significantly lower concentrations than those discerned through other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.

Any positive result in the Screening segment undergoes verification via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples with preliminary positive results are washed if necessary. The complete laboratory procedure from Accessioning to Confirmation is conducted adhering to both CAP (College of American Pathologists) Hair designation standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection timeline: Hair drug tests can identify drug usage for as long as 90 days, contrasting the shorter detection periods offered by urine tests.
• Challenging to manipulate: Tampering with a hair drug test is notably difficult, enhancing result accuracy.
• Yields historical insight: It provides data on patterns of drug use over time, rather than reflecting only recent consumption.

Limitations:

• Cannot identify recent consumption: It requires approximately 5-7 days for substances to manifest in hair.
• Expense: Hair drug screening often incurs higher costs relative to alternative methods.
• Result variability: Factors such as hair shade and personal hair growth differences can influence drug metabolite concentrations within hair strands.

Note: Although often termed "hair follicle tests", the examination analyzes the hair strand, not the follicle under the scalp.
