Hair Follicle Drug Testing - San De Fuca, WA

What it is, How it works

Hair testing is recognized as a significant method for identifying drug and alcohol consumption. Hair captures a long-term record of substance use by embedding biomarkers within its growing fibers. When harvested close to the scalp, hair offers up to an estimated 3-month detection span for alcohol and drugs. Hair collection is straightforward, relatively challenging to tamper with, and uncomplicated to transport.

A 1.5-inch sample consisting of approximately 200 strands of hair (resembling the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, ideal for initial screening and subsequent confirmation. For EtG, additional tests, and/or panels exceeding ten, 150mg of specimen is advisable. A jeweler’s scale is recommended for weighing the specimen. Should scalp hair be unavailable, an equivalent quantity of body hair can be gathered. In our context, head hair refers explicitly to scalp hair. Other forms of hair (facial, axillary, etc.) are categorized as body hair.

Process Overview

The laboratory handling of a drug test result comprises four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into a laboratory’s database. This phase ensures the sample’s seal and shipment are intact, assigns a unique LAN (Laboratory Accessioning Number), and completes any supplemental data input not captured by an electronic chain of custody system.

Screening performs a rapid preliminary check for drugs of abuse. Although Screening is an economical approach to exclude drug usage for most samples, any positive result requires confirmation for legal admissibility. Samples with presumptive positive findings in Screening necessitate an additional confirmation step.

Should a sample test presumptively positive during Screening, additional hair is extracted from the original specimen for the Extraction process. Here, drugs are isolated from hair at significantly lower concentrations than in alternate methods (e.g., urine or oral fluid), rendering hair drug screening the most arduous technique.

Positive screening confirmations are executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo a requisite wash before confirmation. The complete lab procedure from Accessioning through Confirmation receives examination under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can uncover drug usage for up to 90 days, unlike urine tests which offer a shorter detection span.
• Challenge to falsify: Hair drug tests are challenging to deceive, resulting in more reliable outcomes.
• Offers historical insight: It illustrates a timeline of drug consumption, not merely recent usage.

Limitations:

• Lacks recent use detection: Drugs require about 5-7 days to become detectable in hair.
• Expense: Hair drug tests generally incur higher costs compared to other testing methods.
• Result variability: Variations like hair color and individual hair growth can influence drug metabolite concentrations in hair.

Note: While often termed "hair follicle tests", the procedure analyzes the hair strand rather than the follicle below the scalp.
