Hair Follicle Drug Testing - Jefferson, VA

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol usage. Hair can offer a prolonged history of alcohol and other substances by capturing biomarkers within the strands as they grow. When gathered near the scalp, hair can yield up to a 3-month detection period for alcohol and other drugs. It's easy to gather, not easily tampered with, and convenient to ship.

A 1.5-inch sample consisting of around 200 hair strands (comparable to the width of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal sample for screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, a 150mg sample is suggested. It's advisable to weigh the specimen using a jeweler’s scale. If scalp hair isn't accessible, an equivalent amount of body hair may be taken. When we mention head hair, we specifically mean scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The four primary steps in the laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial processing of a sample into a laboratory’s system. This step includes verifying that the sample was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not available through an electronic chain of custody system.

Screening involves a preliminary quick examination for drugs of abuse. Although Screening is an economical approach to rule out drug use on most samples, a positive screen must be confirmed to be valid in legal settings. Any samples that are initially positive in Screening do need a secondary confirmation.

If a sample is initially positive in the Screening stage, more hair is taken from the initial specimen and prepared for Extraction. In this phase, drugs are extracted from hair at a considerably lower concentration than in other methodologies (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.

Confirmation of any positive screening result is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All initially positive samples are cleansed before confirmation as required. The entire laboratory process from Accessioning to Confirmation is carried out under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests that have a more limited detection window.
• Difficult to manipulate: It's quite challenging to manipulate a hair drug test, enhancing the accuracy of the results.
• Reveals historical data: It can show a trend of drug use over a period, not just recent consumption.

Limitations:

• Cannot identify recent use: It takes roughly 5-7 days for drugs to be detectable in hair.
• Expense: Hair drug tests typically cost more than other drug testing techniques.
• Result variations: Aspects like hair color and individual differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Although commonly termed as "hair follicle tests", the test itself evaluates the hair strand and not the hair follicle underneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Jefferson, VA:

Employers and organizations prefer hair follicle testing for superior detection capabilities over traditional urine tests.
