Hair Follicle Drug Testing - Saint Helena, NE

What it is, How it works

Hair examinations have gained recognition as an effective means for identifying drug and alcohol consumption. Hair offers an extended history of substance use by embedding biomarkers within the strands as they grow. When collected close to the scalp, hair can deliver up to nearly a 3-month detection period for alcohol and drugs. Hair is easy to gather, somewhat challenging to tamper with, and simple to transport.

A sample of 1.5 inches, consisting of approximately 200 strands (around the diameter of a #2 pencil) nearest to the scalp, yields 100mg of hair, the optimal quantity for analysis and confirmation. For EtG, add-ons, or tests exceeding 10 panels, 150mg of the sample is advised. We suggest utilizing a jeweler’s scale for measurement. If scalp hair cannot be obtained, an equivalent volume of body hair may be used. References to head hair pertain specifically to scalp hair. Body hair encompasses all other hair types (e.g., facial, axillary, etc.).

Process Overview

The procedure involved in lab processing of a drug test result comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial handling of a specimen within a lab’s system. This process includes ensuring that the sample was securely sealed and transported correctly, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.

Screening represents a preliminary rapid assessment for drugs of abuse. Although Screening offers a cost-efficient method to rule out drug usage for most samples, a positive result must be confirmed for legal admissibility, necessitating a secondary confirmation for any samples deemed presumptively positive.

If Screening indicates a presumptive positive, further hair is extracted from the initial sample and readied for Extraction. During this phase, drugs are extracted from hair at a significantly lower concentration than alternative methods (e.g., urine or oral fluid), making hair drug screening the most challenging approach to conduct.

Confirmation for any positive screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleansed before confirmation if necessary. The complete lab process, from Accessioning to Confirmation, is overseen in alignment with both the CAP (College of American Pathologists) Hair criteria and 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, in contrast to urine tests with a shorter detection span.
• Hard to falsify: Cheating a hair drug test is exceedingly difficult, enhancing result accuracy.
• Supplies historical data: It can exhibit a pattern of drug consumption over an extended timeframe, not merely recent usage.

Limitations:

• Unable to detect recent use: It requires roughly 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests tend to be more costly compared to other drug testing methods.
• Result variations: Factors like hair color and individual differences in hair growth can influence the concentration of drug metabolites in hair.

Note: Despite often being termed as "hair follicle tests", the examination assesses the hair strand, not the follicle beneath the scalp.
