Hair Follicle Drug Testing - Normandy, MO

What it is, How it works

Hair analysis is increasingly regarded as a potent means for identifying the use of drugs and alcohol. The strands offer a comprehensive timeline of substance use by capturing biomarkers within the growing fibers. When samples are taken near the scalp, they can reveal drug and alcohol consumption for up to three months. The collection process is straightforward, the sample is less susceptible to tampering, and shipping is uncomplicated.

A sample size of 1.5 inches containing roughly 200 hair strands (equivalent to a #2 pencil diameter) taken nearest to the scalp yields about 100mg, which is optimal for both screening and confirmation tests. For EtG, additional components, or tests exceeding 10 panels, a 150mg sample is suggested. It is advisable to weigh the sample using a jeweler’s scale. In cases where scalp hair is unavailable, an equivalent body hair quantity can be gathered. References to head hair pertain specifically to scalp hair, while body hair encompasses all other types (such as facial or underarm hair).

Process Overview

The laboratory procedure for processing drug test outcomes consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary phase of integrating a sample into a lab’s framework. This stage involves affirming the sample's proper sealing and shipment, assigning it a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.

Screening entails an initial rapid assessment for substance abuse indicators. While cost-effective for eliminating drug usage suspicions in most cases, positive screenings necessitate confirmation for legal validation. Samples flagged as presumptively positive in the Screening phase must undergo further confirmation.

Upon a presumptive positive result during Screening, additional hair is drawn from the initial sample for the Extraction phase. Here, substances are extracted from hair at notably lower concentrations than other methods (e.g., urine or saliva testing), making hair drug screening the most challenging method to execute.

Positive screening confirmations are performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Samples identified as presumptive positives undergo washing prior to confirmation as required. The entire lab process, from Accessioning to Confirmation, undergoes review according to the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for as long as 90 days, unlike urine tests with a shorter detection span.
• Difficult to compromise: Cheating a hair drug test is challenging, enhancing result accuracy.
• Historical usage data: It offers insights into patterns of drug use over time, not solely recent consumption.

Limitations:

• Cannot identify recent use: Detection of drugs in hair requires about 5-7 days post-consumption.
• Expense: Hair drug tests generally incur higher costs than other testing methods.
• Result variability: Hair color, growth variations, and individual factors can influence drug metabolite concentrations in hair.

Note: Despite often being called "hair follicle tests", the analysis is performed on the hair strand itself, not the follicle beneath the skin.
