Hair Follicle Drug Testing - Riley, OR

What it is, How it works

Hair analysis has evolved as a robust means for identifying alcohol and drug presence. Hair captures a long-term record of alcohol and drug exposure by embedding biomarkers within the hair strand fibers. When sampled near the scalp, hair offers up to an approximately 90-day detection timeline for both alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and convenient for transport.

A sample measuring 1.5 inches with approximately 200 hair strands (similar in size to a #2 pencil) closest to the scalp will provide 100mg of hair, the optimal amount for initial evaluation and verification. For EtG, extended panels, or tests exceeding 10 panels, a collection of 150mg is suggested. Utilizing a jeweler’s scale for weighing the specimen is advisable. If head hair is unavailable, an equal volume of body hair may be utilized. When mentioning head hair, this refers exclusively to scalp hair. Other types of hair (facial, axillary, etc.) constitute body hair.

Process Overview

The laboratory procedure for processing a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a specimen into a laboratory's framework. This involves confirming proper sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data input not furnished by an electronic chain of custody system.

Screening comprises an initial expedited assessment for substance abuse. Although Screening is a budget-friendly method to exclude drug presence in most specimens, a confirmed result is necessary for judicial acceptability. Any specimen that tests presumptively positive during Screening requires an additional confirmation step.

If a specimen is tentatively positive during the Screening phase, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are retrieved from hair at considerably lower concentrations than seen in other methods (e.g., urine or oral fluid), hence why hair drug analysis is considered the most challenging methodology.

Confirmation of any positive Screening result is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that register presumptive positives undergo washing before confirmation if required. The comprehensive lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and the accreditation in alignment with ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection span: Hair tests can identify drug use for up to 90 days, unlike urine tests which have reduced detection periods.
• Challenge of deception: Cheating a hair drug test is notably difficult, leading to more reliable outcomes.
• Offers usage history: It reveals a chronological pattern of drug use over a time span, beyond immediate consumption detection.

Limitations:

• Inability to detect recent use: Drugs become visible in hair approximately 5-7 days post-consumption.
• Expense: Hair drug tests typically incur higher costs than other testing approaches.
• Result variability: Elements like hair color and individual growth rates can alter drug metabolite concentrations in the hair.

Note: While frequently termed "hair follicle tests", the analysis actually involves the hair strand, not the follicle beneath the scalp.
