Hair Follicle Drug Testing - Katherine, AZ

What it is, How it works

Hair analysis is now recognized as an effective means for identifying the use of drugs and alcohol. Hair offers an extended history of alcohol and drug consumption by retaining biomarkers in the fibers of the growing hair strand. When collected near the scalp, hair can provide an approximately 3-month detection period for alcohol and drugs. Hair is straightforward to gather, moderately hard to tamper with, and simple to send.

A 1.5-inch sample of around 200 hair strands (similar to the diameter of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the perfect sample for screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, 150mg of the sample is advised. We advise weighing the sample on a jeweler’s scale. If scalp hair isn’t accessible, an equal amount of body hair can be utilized. When we mention head hair, we mean scalp hair only. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning encompasses the initial intake of a sample into a laboratory’s workflow. This involves ensuring the sample was sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any remaining data input absent from an electronic chain of custody system.

Screening carries out an initial rapid evaluation for drugs of abuse. Although Screening offers an economical way to dismiss drug usage in most samples, a confirmed positive is required for legal admissibility. Any samples that indicate presumptive positivity in Screening necessitate further confirmation.

If a sample indicates positivity in the Screening phase, additional hair is extracted from the original sample and prepped for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations than in other strategies (such as urine or oral fluid), which explains why hair drug screening is the most challenging method to undertake.

Confirmation of any positive screening outcome is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The entire lab process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection period.
• Challenging to falsify: It's extremely challenging to falsify a hair drug test, ensuring more reliable results.
• Delivers historical insights: It offers a pattern of drug usage over time, not simply recent consumption.

Limitations:

• Inability to detect recent consumption: It takes roughly 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug tests are generally costlier than alternative drug testing methods.
• Result variability: Elements like hair color and personal variations in hair growth can influence the concentration of drug metabolites in hair.

Note: While commonly known as "hair follicle tests", the analysis is conducted on the hair strand and not the follicle beneath the scalp.
