Hair Follicle Drug Testing - Sheldahl, IA

What it is, How it works

Hair testing has emerged as an effective resource for identifying the use of drugs and alcohol. Hair strands can retain biomarkers in their fibers, providing a lengthy record of substance use. When acquired close to the scalp, hair can reflect up to about a 3-month timeline for detecting alcohol and other drugs. Hair collection is straightforward, relatively tough to tamper with, and easy to transport.

A sample of 1.5 inches consisting of roughly 200 strands (around the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, considered optimal for screening and confirmation. For EtG, add-ons, and/or tests beyond 10 panels, 150mg of hair is recommended. Measuring the specimen with a jeweler’s scale is advisable. If scalp hair is unavailable, a similar amount of body hair can be gathered. References to head hair specifically pertain to scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

The core steps in processing a drug test at the laboratory include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary handling of a sample within a lab system. This stage ensures the sample's secure sealing and shipment, assigns a LAN (Laboratory Accessioning Number) randomly, and fills in extra data that might not be covered by an electronic chain of custody process.

Screening involves a preliminary check for drug use. Though Screening is an economical means to exclude drug presence in most samples, a confirmed screen result is necessary to be legally valid. Samples showing preliminary positive results in Screening require further confirmation.

Should a sample indicate a presumptive positive during Screening, additional hair is taken from the main specimen for Extraction. During this, drugs are sourced from the hair at much lower concentrations compared to other techniques (e.g., urine or oral fluid), explaining why hair drug screening is notably challenging.

To confirm any positive screen results, methods such as GC/MS, GC/MS/MS, or LC/MS/MS are employed. All samples deemed presumptively positive undergo a wash before confirmation when necessary. The full laboratory process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair specifications and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair tests can identify drug use extending to 90 days, which is longer than the detection window of urine tests.
• Hard to manipulate: The difficulty in cheating a hair drug test enhances the accuracy of the results.
• Reveals historical patterns: It can indicate habitual drug use over time, unlike recent or singular use.

Limitations:

• Cannot pinpoint recent use: Detecting drugs in hair takes around 5-7 days.
• Expense: Hair drug tests generally carry a higher cost compared to other methods.
• Result variability: Drug metabolite concentration in hair can be influenced by factors such as hair color and individual growth rates.

Note: Despite being called "hair follicle tests," the analysis involves the hair strand, not the follicle beneath the scalp.
