Hair Follicle Drug Testing - Lena, LA

What it is, How it works

Hair evaluation is increasingly recognized as an effective method for identifying drug and alcohol consumption. The hair captures a comprehensive account of alcohol and other substances by embedding biomarkers in its growing strands. When gathered near the scalp, hair can offer up to a 3-month period of detection for alcohol and drugs. The process is straightforward for collection, relatively tamper-resistant, and convenient for transport.

A segment of 1.5 inches of roughly 200 hair strands (comparable to a #2 pencil) near the scalp yields 100mg of hair, the preferred quantity for testing and verification. For EtG add-ons or tests exceeding 10 panels, 150mg of the specimen is advisable. It is prudent to use a jeweler’s scale for weight measurement. If scalp hair is absent, an equivalent volume of body hair is acceptable. Mention of head hair pertains exclusively to scalp hair, whereas body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

The processing of a drug test result in a laboratory comprises four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial incorporation of a sample into a laboratory's records. This phase involves confirming the sample's seal and shipment integrity, generating a unique LAN (Laboratory Accessioning Number), and completing any supplementary data input not included in an electronic chain of custody system.

Screening constitutes an expedited preliminary examination for substances of abuse. Though Screening serves as an economical method to dismiss drug use in many instances, a positive result necessitates confirmation to be legally valid. Samples with a presumptive positive result in Screening require subsequent confirmation.

Upon obtaining a presumptive positive in Screening, additional hair is extracted from the initial sample and processed for Extraction. This phase involves extracting drugs from the hair at a significantly lower concentration compared to other techniques (e.g., urine or oral fluid), rendering hair drug screening the most challenging methodology to execute.

Positive screening outcomes undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are washed prior to confirmation if required. The entire laboratory procedure, from Accessioning to Confirmation, is subject to review under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can ascertain drug use extending up to 90 days, unlike urine tests, which offer a shorter detection span.
• Resistance to tampering: Hair drug tests are difficult to falsify, ensuring more reliable outcomes.
• Records historical usage: They can illustrate a drug usage pattern over time, rather than merely recent use.

Limitations:

• Inability to detect recent use: It takes about 5-7 days for drugs to become discernible in hair.
• Expense: Hair drug tests generally incur higher costs compared to other testing methods.
• Result variability: Elements such as hair color and individual growth rates can influence drug metabolite concentration in hair.

Note: Although often termed "hair follicle tests", the analysis pertains to the hair strand, not the follicle beneath the scalp.
