Hair Follicle Drug Testing - Stella, LA

What it is, How it works

Hair testing is recognized as a potent method for identifying drug and alcohol usage. Hair can retain a prolonged history of substance exposure by encapsulating markers within the fibers of emerging hair. Sampling near the scalp, hair can reveal up to around a 3-month detection span for alcohol and drugs. Collection of hair is straightforward, relatively hard to taint, and simple to transport.

A hair sample of 1.5 inches with roughly 200 strands (about as thick as a #2 pencil) closest to the scalp yields 100mg of hair, the optimal quantity for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the specimen is advisable. We suggest verifying the specimen's weight using a jeweler’s scale. If hair from the scalp cannot be acquired, an equivalent amount of body hair is acceptable. By head hair, we mean scalp hair alone. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the sample's preliminary integration into the laboratory system, ensuring the sample was sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and executing any supplementary data entry absent from an electronic chain of custody system.

Screening consists of a swift initial inspection for substances of abuse. Screening offers an economical means to negate drug consumption in most samples; however, a positive result must be verified for it to stand in legal settings. Samples yielding a presumptive positive in Screening require further confirmation.

Should a sample yield a presumptive positive during Screening, additional hair is extracted from the original sample and prepped for Extraction. This phase involves extracting drugs from hair at a far lower concentration compared to other methods (e.g., urine or oral fluids), highlighting the complexity of hair drug screening.

Confirmation of any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed prior to confirmation as needed. The complete laboratory workflow from Accessioning to Confirmation is overseen following both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can indicate drug use for as long as 90 days, unlike urine tests with a shorter detection timeline.
• Resistance to tampering: Tampering with a hair drug test is exceptionally difficult, enhancing result reliability.
• Historical usage data: It can reveal a pattern of substance use over time, not limited to recent consumption.

Limitations:

• Incapable of detecting immediate usage: A delay of about 5-7 days is required for drugs to be identifiable in hair.
• Expense: Hair drug tests typically incur greater costs than other testing procedures.
• Result variability: Elements like hair color and individual growth differences may influence drug metabolite concentration in hair.

Note: Commonly termed "hair follicle tests", the actual examination pertains to the hair strand instead of the follicle beneath the scalp.
