Hair Follicle Drug Testing - Oakdale, LA

What it is, How it works

Hair testing has gained recognition as a potent method for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drug exposure by embedding biomarkers within the fibers of the developing hair shaft. When sampled near the scalp, hair can reveal up to about a 3-month detection period for alcohol and drugs. Hair is straightforward to gather, relatively hard to tamper with, and simple to transport.

A 1.5-inch segment of roughly 200 hair strands (about the size of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample for examination and validation. For EtG, add-ons, and/or tests surpassing 10 panels, 150mg of the specimen is suggested. Employ a jeweler’s scale to weigh the specimen. If scalp hair is lacking, a comparable quantity of body hair can be collected. When mentioning head hair, it refers solely to scalp hair. Body hair encompasses all other hair types (e.g., facial, axillary, etc.).

Process Overview

The four major steps in the lab handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning concerns the primary processing of a sample within a lab's framework. This incorporates validating that the sample was secured and sent correctly, allocating a random LAN (Laboratory Accessioning Number), and completing any further data entry missing from an electronic chain of custody system.

Screening entails an initial rapid assessment for drugs of abuse. Though Screening is an economical way to dismiss drug use in most samples, a positive screen must be verified to be court-admissible. Any samples that are presumptively positive during Screening necessitate a secondary verification.

If a sample is presumptively positive during the Screening phase, additional hair is extracted from the initial specimen and readied for Extraction. In this phase, drugs are extracted from hair at a significantly lower concentration than in other methods (e.g., urine or oral fluid), which explains why hair drug screening is the most challenging method to execute.

The confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The comprehensive laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can discover drug use for up to 90 days, unlike urine tests which have a brief detection span.
• Difficulty to cheat: It is very challenging to deceive a hair drug test, resulting in more precise outcomes.
• Provides historical data: It can offer a pattern of drug use over an extended timeframe, not merely recent use.

Limitations:

• Cannot detect recent use: It takes about 5-7 days for drugs to become detectable in hair.
• Cost: Hair drug tests are typically pricier than other drug testing approaches.
• Variations in results: Elements like hair color and individual differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Although commonly termed "hair follicle tests", the test itself examines the hair shaft and not the hair follicle beneath the scalp
