Hair Follicle Drug Testing - Longstreet, LA

What it is, How it works

Hair tests are now recognized as an effective method for identifying drug and alcohol usage. Hair retains biomarkers within the growing strand, offering an extended history of substance use. A sample taken near the scalp can reveal drug and alcohol use for a period of up to roughly three months. It's straightforward to gather, relatively tamper-proof, and easy to send.

A 1.5-inch segment consisting of around 200 hair strands (comparable to the width of a #2 pencil) closest to the scalp will provide 100mg, which is the optimum sample for testing and verification. For tests like EtG, add-ons, and those exceeding ten panels, a 150mg specimen is advised. It's suggested to measure the sample with a jeweler’s scale. In the absence of scalp hair, a comparable quantity of body hair can be used. Scalp hair refers specifically to hair from the head, while body hair covers all other hair forms (such as facial or axillary hair).

Process Overview

The main steps in laboratory processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial integration of a specimen into the lab’s system, which involves confirming the sample is sealed and transported correctly, giving a random LAN (Laboratory Accessioning Number), and completing data entry tasks not fulfilled by an electronic chain of custody.

Screening encompasses a swift initial assessment for drug presence. While Screening is an economical means to assess most samples for drug use, a positive screen requires confirmation for legal admissibility. Any samples presumed positive during Screening need confirmation through secondary testing.

Should a sample yield a presumptive positive during Screening, additional hair is extracted from the primary specimen for the Extraction phase. At this stage, drugs are removed from hair at significantly lower levels compared to other methods (such as urine or oral fluid), highlighting the complexity of hair drug screening.

Confirmation of any positive screen is done using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, presumptive positive samples are cleansed as necessary. The full lab process from Accessioning to Verification is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can identify drug use up to 90 days, while urine tests have a reduced detection timeframe.
• Hard to tamper with: The accuracy of hair drug tests is high due to the difficulty in cheating the test.
• Shows past usage: They reveal a usage pattern over time, not just recent intake.

Limitations:

• Cannot identify recent use: Drugs become detectable in the hair after approximately 5-7 days.
• Cost: Typically, hair drug tests are pricier than other methods.
• Variability in outcomes: Factors like hair color and individual hair growth variations can influence drug metabolite levels in the hair.

Note: Generally named "hair follicle tests", the examination focuses on the hair strand itself and not on the follicle beneath the scalp.
