Hair Follicle Drug Testing - Angie, LA

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair holds a comprehensive record of alcohol and drug intake by encapsulating biomarkers within the strands as they develop. Hair collected near the scalp offers a detection period for alcohol and drugs of up to roughly 3 months. The collection process is straightforward, relatively resistant to tampering, and convenient for shipping.

A sample measuring 1.5 inches, consisting of about 200 hair strands (comparable to a #2 pencil thickness) near the scalp, provides 100mg of hair, which is ideal for testing and verification. For EtG, additional analyses, and tests exceeding 10 panels, a 150mg sample is advised. Using a jeweler’s scale is suggested for weighing the sample. In the absence of scalp hair, an equivalent amount of body hair may be used. References to head hair pertain strictly to scalp hair, whereas body hair includes all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four major stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a specimen is integrated into a laboratory’s system. This process involves ensuring the sample was correctly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry not managed by an electronic chain of custody system.

Screening provides an initial rapid assessment for the presence of drugs. Although Screening is an economical method to eliminate drug usage in most cases, any positive outcomes require confirmation for legal purposes. Therefore, any samples registering a presumptive positive result in Screening necessitate additional confirmation.

Should a sample show a presumptive positive in the Screening phase, further hair is drawn from the original sample and prepared for Extraction. This stage extracts drugs from hair at significantly lower concentrations than in other testing methods (such as urine or oral fluid), contributing to the complexity of performing hair drug screening.

Positive results from the screening phase undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are washed as necessary. The entire laboratory procedure, from Accessioning to Confirmation, is conducted under the CAP (College of American Pathologists) Hair guidelines and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use over the past 90 days, unlike urine tests which detect usage over a shorter period.
• Resilience to manipulation: Altering the outcome of a hair drug test is notably challenging, enhancing result accuracy.
• Historical insight: It reveals a timeline of drug use rather than just current activities.

Limitations:

• Incapability to detect recent usage: It requires approximately 5-7 days for drugs to be detectable in hair.
• Expense: Hair drug tests typically cost more than other methods of drug testing.
• Result variability: Factors like hair color and personal differences in hair growth can influence drug metabolite concentrations in hair.

Note: Commonly called “hair follicle tests”, the analysis focuses on the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle tests surpass urine testing in their ability to detect drug use with greater accuracy, especially in Angie, LA. While urine tests are common, hair testing offers enhanced detection capabilities, revealing substance use patterns over a longer period.
