Hair Follicle Drug Testing - Woodlake, VA

What it is, How it works

The use of hair testing has emerged as an effective means for identifying drug and alcohol consumption. Hair captures a history of alcohol and drug use over time by embedding biomarkers within the fibers as the hair grows. When taken close to the scalp, a hair sample can offer up to a three-month detection period for alcohol and other substances. Hair collection is straightforward, challenging to tamper with, and it's easily shipped.

A 1.5-inch portion of around 200 hair strands (akin to the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample size for initial testing and confirmation. For EtG, additional tests, or panels above ten, a sample of 150mg is suggested. It's advisable to measure the sample using a jeweler’s scale. If scalp hair isn't available, a comparable amount of body hair may be used. When we mention head hair, it pertains only to scalp hair, contrasting with body hair, which encompasses all other types (such as facial, axillary hair).

Process Overview

The key stages in the laboratory processing for a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial processing of a sample within the laboratory’s system. This step includes confirming that the sample was securely sealed and sent correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody system.

Screening provides an initial assessment for substance abuse. While it is a budget-friendly technique to exclude drug use for most samples, positive results in Screenings require further confirmation for legal admissibility. Any samples that are deemed presumptively positive during Screening necessitate a follow-up confirmation.

If a sample tests presumptively positive in the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. During this phase, drugs are drawn from hair at a significantly lower concentration than with other methods (e.g., urine or oral fluid), which makes hair drug testing the most challenging methodology.

Confirmation of any positively screened result is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptive positive are washed before confirmation, if required. The entire lab procedure from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, as opposed to urine tests which offer a shorter detection timeframe.
• Hard to fake: It is extremely difficult to fake a hair drug test, thus ensuring more reliable results.
• Historical usage data: It illustrates a timeline of drug use, beyond just recent consumption.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair about 5-7 days after use.
• Cost factor: Hair drug tests tend to be more costly than other testing methods.
• Result variability: Variables such as hair color and individual growth differences can influence the levels of drug metabolites found in the hair.

Note: Although often called "hair follicle tests", the analysis is performed on the hair strand, not the follicle beneath the scalp
