Hair Follicle Drug Testing - Haivana Nakya, AZ

What it is, How it works

Hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. Hair offers an extended timeline of alcohol and drug use by encapsulating biomarkers within the fibers of the hair as it grows. When hair is collected near the scalp, it can deliver up to a 3-month detection period for alcohol and drug usage. Hair collection is straightforward, moderately challenging to tamper with, and easily shipped.

A 1.5-inch section of approximately 200 hair strands (roughly equivalent to a #2 pencil in thickness) close to the scalp will yield 100mg of hair, the ideal sample for screening and validation. For EtG enhancements, and/or tests exceeding 10 panels, 150mg of the sample is advised. Using a jeweler’s scale to weigh the specimen is recommended. In the absence of scalp hair, an equivalent volume of body hair may be used. When mentioning head hair, we mean scalp hair exclusively. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the preliminary processing of a sample into the laboratory's system. This comprises ensuring the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry absent from an electronic chain of custody system.

Screening involves a preliminary rapid analysis for drugs of misuse. While screening serves as a cost-efficient means to dismiss drug use in most specimens, a positive screening result necessitates confirmation to be legally viable. Samples with positive preliminary results in screening do require a subsequent confirmation.

Should a sample show a positive preliminary result in screening, additional hair is taken from the original specimen and prepared for extraction. In this phase, drugs are retrieved from hair at significantly lower concentrations than alternative methodologies (e.g., urine or oral fluid), rendering hair drug screening as the most challenging method to execute.

Validation of any preliminary positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with preliminary positive readings are cleansed before the confirmation process as required. The full laboratory process from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use for as long as 90 days, surpassing urine tests that have a shorter detection window.
• Challenge to circumvent: Cheating on a hair drug test is extremely tough, leading to more precise results.
• Offers historical insight: It reveals a timeline of drug consumption over months, not just recent usage.

Limitations:

• Incapable of recent detection: It requires an estimated 5-7 days for drugs to become identifiable in hair.
• Expense: Hair drug tests usually incur higher costs than other drug testing techniques.
• Result variability: Elements such as hair color and personal differences in hair growth can alter the drug metabolites concentration in hair.

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

Why Hair Follicle Testing Beats Urine Testing

In Haivana Nakya, AZ, the advantages of hair follicle tests over urine tests are well-documented. Hair testing offers a broader detection window and is practically immune to consumption evasion tactics.

This results in increased confidence in test outcomes.

Extended Detection Window

Hair follicle testing conducts a more extended review of drug use history in Haivana Nakya, AZ. An unprecedented detection window up to 90 days means employers and authorities gain a comprehensive overview, unlike shorter-term urine tests. Thus, the ability to detect historical use grants companies a better understanding of patterns, supporting more informed hiring and monitoring decisions.

Tamper-Resistant Testing Method

Haivana Nakya, AZ, values the integrity of hair follicle testing for its tamper-resistant advantages. Such tests reduce adulteration risks, unlike urine specimens.
