Hair Follicle Drug Testing - Linden, AZ

What it is, How it works

Hair testing is recognized as a robust method for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and drug use by embedding biomarkers within the fibers of the growing hair strand. Collected near the scalp, hair can offer a detection window of up to approximately 3 months for alcohol and drugs. Hair collection is straightforward, moderately resistant to adulteration, and convenient for shipping.

A sample approximately 1.5 inches long, consisting of about 200 hairs (roughly the diameter of a #2 pencil) closest to the scalp provides 100mg of hair, the optimal sample for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advisable. We suggest using a jeweler’s scale for specimen measurement. If scalp hair is not available, an equivalent amount of body hair can be used. References to head hair pertain to scalp hair exclusively, while body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning is the initial phase where a sample is entered into a laboratory’s system. This comprises confirming that the sample was properly sealed and shipped, generating a random LAN (Laboratory Accessioning Number), and completing any additional data entry not provided by an electronic chain of custody system.

Screening is a preliminary rapid test for drugs of abuse. While Screening is a cost-efficient means to rule out drug usage in most samples, a positive result requires confirmation to be legally admissible. Samples that show a presumptive positive in Screening necessitate a subsequent confirmation.

If the sample shows a presumptive positive at the Screening stage, additional hair is taken from the initial specimen for Extraction. At this stage, drugs are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging procedure to carry out.

Confirmation of any positive screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing prior to confirmation as necessary. The entire laboratory procedure, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection range: Hair drug tests can identify drug use for up to 90 days, in contrast to urine tests which have a briefer detection range.
• Resistance to tampering: It is exceedingly hard to tamper with a hair drug test, ensuring the accuracy of results.
• Provides usage history: It can reveal a long-term pattern of drug use, not just recent consumption.

Limitations:

• Unable to detect recent use: It takes around 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests typically have a higher cost compared to other drug testing techniques.
• Result variability: Elements such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Although often termed "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp.
