Hair Follicle Drug Testing - Terry, LA

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol use. Hair retains a long-term record of substance consumption by embedding biomarkers within the developing hair strand. When taken from near the scalp, hair can offer up to roughly a 3-month period of detection for alcohol and various drugs. Hair is straightforward to obtain, somewhat resistant to tampering, and convenient to transport.

A 1.5-inch segment comprising around 200 hair strands (comparable in size to a #2 pencil) nearest the scalp yields 100mg of hair, which is optimal for initial and confirmatory testing. For EtG, additional tests, or panels exceeding 10, 150mg of hair is suggested. It's advised to measure the specimen's weight using a jeweler’s scale. If scalp hair is unavailable, a similar quantity of body hair may be collected. References to head hair exclusively pertain to scalp hair. Body hair includes all other types of hair (facial, axillary, etc.).

Process Overview

The four essential phases in lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves initially registering a sample in a laboratory’s system. This step includes confirming that the sample was securely packaged and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data not provided electronically by a chain of custody system.

Screening entails a preliminary assessment for drugs of abuse. Although Screening is an economical way to dismiss drug usage in most samples, verifying a positive screen is necessary for it to be admissible in legal proceedings. Samples that show presumptive positives in Screening must undergo a secondary confirmation.

Should a sample appear presumptive positive during Screening, additional hair is extracted from the initial specimen and prepared for Extraction. In this phase, drugs are extracted from hair at a much lower concentration than other methods (e.g., urine or oral fluid), making hair drug screening one of the most challenging methodologies.

Confirmation of any positive results from screening is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed to be positive are cleansed prior to confirmation as necessary. The comprehensive laboratory process from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair guidelines and adheres to the ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can identify drug use for as long as 90 days, unlike urine tests, which have a shorter detection time frame.
• Difficulty in falsifying: Hair drug tests are notably challenging to cheat, thus enhancing result accuracy.
• Supply historical insights: Hair tests can map drug consumption patterns over an extended timeframe, beyond recent use.

Limitations:

• Inability to detect recent usage: Drugs take about 5-7 days to become detectable in hair.
• Expense: Generally, hair drug tests are costlier than other drug testing techniques.
• Variability in outcomes: Elements like hair color and personal differences in hair growth can influence drug metabolite levels in hair.

Note: Often termed "hair follicle tests", the analysis targets the hair strand rather than the follicle beneath the scalp.
