Hair Follicle Drug Testing - Dodson, LA

What it is, How it works

Hair analysis has gained recognition as an influential method for identifying drug and alcohol consumption. Hair offers an extended chronology of alcohol and drug presence by securing biomarkers within the developing hair fiber. When taken near the scalp, hair can reveal approximately a three-month detection span for alcohol and drugs. Hair is easy to gather, somewhat challenging to tamper with, and simple to transport.

A 1.5-inch segment comprising approximately 200 hair fibers (akin to the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, the preferred quantity for both screening and confirmatory testing. For EtG evaluations, add-ons, and tests exceeding 10 panels, a 150mg sample is advised. We recommend measuring the sample with a jeweler’s scale. If scalp hair is not an option, a comparable quantity of body hair can be collected. When noting head hair, we specifically mean scalp hair only. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory process for drug test evaluation comprises four essential stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves initial sample integration into the laboratory’s database. This step includes ensuring the sample was properly sealed and shipped, assigning it a random LAN (Laboratory Accessioning Number), and completing any outstanding data entry not captured by an electronic chain of custody system.

Screening involves a preliminary, rapid assessment for drug abuse. While Screening is a cost-effective method to dismiss drug use in most samples, a positive screen requires validation to be legally valid. Samples presenting presumptive positives in Screening mandate further confirmation.

In the instance of a presumptive positive during Screening, additional hair is extracted from the original sample and prepared for Extraction. At this stage, drugs are removed from the hair at significantly lower concentrations than in other methodologies (e.g., urine or oral fluid), rendering hair drug analysis the most challenging method to execute.

Confirmation of any positive screening findings is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed prior to confirmation as necessary. The comprehensive laboratory procedure from Accessioning to Confirmation undergoes a review under both the CAP (College of American Pathologists) Hair criteria and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests can identify drug consumption for up to 90 days, unlike urine tests which have a narrower detection period.
• Difficult to manipulate: Cheating a hair drug test is quite challenging, resulting in more reliable outcomes.
• Delivers historical data: It can outline drug use over time, rather than solely recent occurrences.

Limitations:

• Inability to detect recent use: It generally takes about 5-7 days for drugs to manifest in hair.
• Expense: Hair drug tests typically incur higher costs than alternative drug testing methods.
• Variability in outcomes: Variables like hair color and personal differences in hair growth can influence the drug metabolite concentration in hair.

Note: Although commonly termed "hair follicle tests", the test analyzes the hair strand itself, not the follicle beneath the scalp
