Hair Follicle Drug Testing - Sil Nakya, AZ

What it is, How it works

Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. By capturing biomarkers within the strands of growing hair, it provides an extended record of alcohol and drug use. When sourced close to the scalp, hair offers a detection period of up to three months for both alcohol and drugs. The collection of hair is straightforward, relatively challenging to tamper with, and convenient to transport.

A sample size of 1.5 inches consisting of about 200 hair strands (comparable to a #2 pencil in thickness) closest to the scalp yields 100mg, which is the optimal sample size for analysis and validation. For EtG, additional tests, and/or screenings exceeding 10 panels, a sample size of 150mg is advised. It is recommended to measure the sample on a jeweler’s scale. If scalp hair is unavailable, an equivalent quantity of body hair may be gathered. The term 'head hair' specifically refers to scalp hair, whereas 'body hair' encompasses all other types (such as facial and axillary).

Process Overview

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

Accessioning is the stage where the sample is first processed and logged into the lab's system. This involves ensuring the sample was properly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional information not provided by an electronic chain of custody system.

Screening involves conducting an initial quick assessment for drugs of abuse. While it is a cost-effective method to eliminate drug use in the majority of cases, a positive result in the screening requires confirmation for legal validity. Samples that are initially positive in Screening necessitate a further confirmation step.

When a sample is tentatively positive during Screening, additional hair is taken from the original sample for the Extraction process. This step involves retrieving drugs from hair at much lower concentrations than other methods (e.g., urine or saliva), making hair drug screening the most challenging to execute.

Confirmation of any positive Screening finding is performed using GC/MS, GC/MS/MS, or LC/MS/MS methods. Before confirmation, all samples that test positive are washed as required. The entire process, from Accessioning to Confirmation, undergoes evaluation under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests can trace drug use for up to 90 days, unlike urine tests with shorter detection spans.
• Hard to alter: Cheating a hair drug test is notably difficult, resulting in more reliable outcomes.
• Tracks usage history: It can outline a pattern of drug use over time, rather than just recent consumption.

Limitations:

• Cannot identify recent drug use: Detection in hair takes about 5-7 days following drug intake.
• Expense: Hair drug testing is typically priced higher than alternative testing methods.
• Result variability: Variables like hair color and individual hair growth differences can influence drug metabolite concentration in hair.

Note: Despite being called "hair follicle tests," the analysis itself examines the hair strand, not the follicle located beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When it comes to drug testing in Sil Nakya, AZ, hair follicle testing offers numerous advantages over traditional urine tests. Superior detection accuracy sets it apart, with hair tests identifying substances over a more extended period.
