Hair Follicle Drug Testing - Wyano, PA

What it is, How it works

Hair testing is widely recognized as an effective method for detecting drug and alcohol consumption. This is due to hair's ability to capture biomarkers along its strands as it grows, offering a comprehensive history of substance use. When hair is sampled close to the scalp, it can reveal substance use for up to roughly three months. Collection of hair is straightforward, it's somewhat resistant to tampering, and it transports easily.

Obtaining a 1.5-inch segment comprising approximately 200 hair strands (equivalent to the girth of a #2 pencil) from the scalp yields around 100mg—an optimal sample size for screening and validation. For EtG and extended tests exceeding 10 panels, a 150mg specimen is recommended. It's advised to use a jeweler's scale for measuring. In the event scalp hair isn't accessible, one may use body hair. Here, 'head hair' specifically refers to scalp hair only, while 'body hair' encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory analysis consists of four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initiation of sample processing within a lab's database. It involves ensuring the sample's proper sealing and shipment, assigning an arbitrary LAN (Laboratory Accessioning Number), and concluding any pending data entries missed by electronic chain-of-custody systems.

Screening offers a preliminary assessment for drug presence. As a cost-efficient strategy, Screening chiefly excludes drug use in the majority of samples; however, to validate for court admissibility, a positive initial result must undergo further verification. Samples showing presumptive positivity in Screening mandate successive confirmation.

When a specimen is likely positive in Screening, additional hair is extracted from the existing sample and prepared for Extraction. Here, substances are concentrated from hair at lower levels compared to other methods (e.g., urine or oral fluids), enhancing the complexity of hair drug screening execution.

Verification of positive Screening outcomes is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with a preliminary positive are, if needed, cleansed before final confirmation. The entire procedure from Accessioning to Confirmation is meticulously examined under both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair testing can identify substance use over a 90-day span, surpassing urine test timelines.
• Challenge in manipulation: Its results are more reliable due to the difficulty in altering hair test samples.
• Chronological insight: It offers an overview of long-term substance usage, unlike tests focusing on recent consumption.

Limitations:

• Recent usage testing is limited: It usually takes drugs 5-7 days to be detectable in hair following use.
• Higher expense: Hair tests generally incur greater costs than alternate methodologies.
• Result inconsistency: Factors such as hair pigmentation and growth rate variability may impact metabolite levels in hair.

Note: While often termed as "hair follicle tests," the analysis targets the hair strand instead of the follicle beneath the skin.
