Hair Follicle Drug Testing - Koyuk, AK

What it is, How it works

The utilization of hair testing has emerged as a potent method for identifying drug and alcohol consumption. Hair offers an extended chronological record of substances by retaining biomarkers within the fibers of the developing hair strand. When gathered near the scalp, hair offers a detection timeframe extending up to roughly 3 months for both alcohol and drugs. The collection process is straightforward, the potential for tampering is relatively low, and the transportation is uncomplicated.

A 1.5-inch segment comprising approximately 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp yields 100mg of hair, representing the optimal sample size for both preliminary screening and subsequent confirmation. For tests involving EtG, additional parameters, and/or over 10 panels, a specimen volume of 150mg is advised. Utilizing a jeweler’s scale is recommended for precise specimen measurement. In scenarios where scalp hair is inaccessible, an equivalent quantity of body hair may be obtained. Our mention of head hair strictly pertains to scalp hair. All other hair types (facial, axillary, etc.) are encompassed under body hair.

Process Overview

The laboratory procedure for processing drug test outcomes comprises four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into the laboratory system. This phase encompasses verifying the sample’s seal and proper shipment, allocating a random LAN (Laboratory Accessioning Number), and finishing any supplementary data entry absent from an electronic chain of custody system.

Screening applies an initial rapid assessment for drugs of abuse. Although Screening provides a cost-effective means to eliminate drug usage in most samples, a positive result necessitates confirmation for court admissibility. Any samples that yield a presumptive positive in Screening mandate a secondary confirmation.

Should a sample yield a presumptive positive during Screening, additional hair is extracted from the initial specimen and ready for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting why hair drug screening stands as one of the most intricate methodologies.

Confirmation of any positive screening outcome is conducted using GC/MS, GC/MS/MS or LC/MS/MS. Before confirmation, all samples labeled as presumptive positives undergo washing if required. The entire laboratory process, spanning from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation along with accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can identify drug consumption for up to 90 days, unlike urine tests which offer a shorter timeframe.
• Resistance to compromise: A hair drug test is exceptionally resistant to tampering, thereby enhancing result accuracy.
• Chronological usage information: It can reveal a historical pattern of drug use over time, beyond just recent consumption.

Limitations:

• Inability to identify recent consumption: Detection in hair takes approximately 5-7 days post-use.
• Expense: Hair drug tests typically incur higher costs than other testing methods.
• Result variability: Factors like hair color and individual hair growth differences can influence the concentration of drug metabolites in hair.

Note: Though colloquially termed as "hair follicle tests", the examination focuses on the hair strand rather than the hair follicle beneath the scalp
