Hair Follicle Drug Testing - Leacock, PA

What it is, How it works

The examination of hair has emerged as an effective approach for identifying drug and alcohol consumption. Hair serves as a long-term record of substances by embedding biomarkers within the hair as it grows. When taken close to the scalp, hair offers up to a three-month window for detecting alcohol and drugs. The collection of hair is straightforward, relatively tamper-resistant, and convenient for transportation.

A sample measuring 1.5 inches, comprising roughly 200 hair strands (equivalent to a #2 pencil in size) nearest the scalp, yields 100mg of hair, the optimal quantity for initial and confirmatory tests. When conducting tests such as EtG or those above 10 panels, a recommendation is to collect 150mg of hair. The use of a jeweler’s scale is advised for weighing the sample. If scalp hair cannot be obtained, a comparable amount of body hair can be used. In this context, head hair specifically means scalp hair, while body hair encompasses all other types (like facial and axillary hair).

Process Overview

The laboratory's evaluation of a drug test result encompasses these four essential steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary integration of a sample into the lab's framework. This step checks that the sample was correctly sealed and dispatched, assigns a Laboratory Accessioning Number (LAN), and completes any further data entry absent from an electronic chain of custody.

Screening is a swift appraisal for illicit substances. Though Screening economically eliminates most negative samples, positives require further validation to be court-acceptable. Presumptive positives from Screening necessitate additional verification.

Should a sample test presumptively positive during Screening, more hair is extracted from the original to prepare for Extraction. This phase retrieves drugs from hair at a significantly lower concentration compared to other methods (like urine or saliva), underscoring the technical challenge of hair drug screening.

Positive results from Screening receive Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives are washed before Confirmation as required. The comprehensive laboratory sequence from Accessioning to Confirmation receives scrutiny under the CAP (College of American Pathologists) Hair protocols and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection duration: Hair tests trace drug usage up to 90 days, unlike urine tests with shorter periods.
• Challenging to falsify: The difficulty of tampering with hair tests ensures accuracy in the results.
• Historical usage insights: It reveals patterns of drug intake over time, beyond just recent consumption.

Limitations:

• Inability to detect recent intake: Detection in hair occurs approximately 5-7 days after use.
• Expense: Hair drug tests are typically pricier compared to other test forms.
• Result variability: Factors such as hair color and individual growth differences can impact metabolite levels in hair.

Note: Commonly termed "hair follicle tests," the analysis targets the hair strand, not the scalp's follicle.

Why Hair Follicle Testing Beats Urine Testing
