Hair Follicle Drug Testing - Saint James, AR

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol consumption. This technique captures biomarkers in the fibers of the developing hair strand, offering a substantial timeline analysis of alcohol and drugs. By collecting hair near the scalp, one can achieve an approximate 3-month detection period for substances. Hair is easy to collect, hard to tamper with, and convenient to ship.

A sample measuring 1.5 inches comprising approximately 200 hair strands (about the size of a #2 pencil) near the scalp represents 100mg of hair, the optimal quantity for screening and confirmation. For EtG, add-ons, and tests exceeding 10 panels, it is advised to gather 150mg of the sample. Utilizing a jeweler’s scale for weighing the sample is suggested. If scalp hair cannot be obtained, an equal volume of body hair can be used. Reference to head hair specifically denotes scalp hair, whereas body hair includes all other types (facial, axillary, etc.).

Process Overview

The lab processing of a drug test outcome encompasses four main phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a lab’s system. This stage verifies the correct sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and concludes any leftover data entry not handled by an electronic chain of custody system.

Screening is the preliminary rapid assessment for drug abuse. This stage provides a cost-effective approach for eliminating drug use in most samples, yet any positive screen needs confirmation to hold court admissibility. Samples with a tentative positive result in Screening necessitate further verification.

Upon a presumptive positive result in Screening, additional hair is extracted from the original sample for Extraction. In this segment, drugs are retrieved from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening notably challenging.

A positive screening result undergoes Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All suspected positive samples are cleansed before confirmation as required. The full lab procedure from Accessioning to Confirmation is reviewed respecting CAP (College of American Pathologists) Hair standards and accreditation under ISO / IEC 17025 protocols.

Advantages of hair drug testing:

• Prolonged detection window: Hair drug tests can trace drug use up to 90 days, whereas urine tests have a limited detection span.
• Challenging to deceive: Hair drug tests are difficult to manipulate, ensuring higher accuracy of results.
• Historical insight: Provides a timeline of drug usage extending beyond recent consumption.

Limitations:

• Late detection of recent use: It requires about 5-7 days for drugs to manifest in hair.
• Expense: Hair drug tests incur higher costs compared to alternative drug testing techniques.
• Result variability: Elements like hair color and individual hair growth may influence drug metabolite concentration in hair.

Note: Commonly known as "hair follicle tests", the procedure examines the hair strand rather than the hair follicle underneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
