Hair Follicle Drug Testing - Zumbro Falls, MN

What it is, How it works

Hair analysis has emerged as an effective method for identifying substance use. Hair retains a long-term record of alcohol and drugs by encapsulating biomarkers within the strands of developing hair. When sampled near the scalp, hair can reveal a detection period of up to around three months for substances. It's easy to gather, challenging to tamper with, and convenient to transport.

A sample length of 1.5 inches, with about 200 strands of hair (roughly the thickness of a #2 pencil) nearest to the scalp, provides 100mg of hair, which is optimal for testing. For EtG, additional tests, and/or panels over 10, 150mg of the hair sample is advised. It's advisable to weigh the sample on a jeweler’s scale. If scalp hair isn't accessible, an equivalent volume of body hair is acceptable. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other forms (facial, armpit, etc.).

Process Overview

The key stages in a laboratory's processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary processing of a sample into the lab's system. This step ensures the sample was properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and includes any extra data input not captured by an electronic chain of custody arrangement.

Screening constitutes an initial swift assessment for substance abuse. Although Screening is a cost-effective measure to negate drug use in most cases, a positive detection necessitates confirmation to be applicable in legal settings. Any samples showing presumptive positive results in Screening demand a subsequent confirmation.

Should a specimen show presumptive positivity during Screening, more hair is taken from the original sample for Extraction preparation. At this juncture, drugs are extracted from hair at much lower concentration levels compared to other methods (e.g., urine or saliva), underscoring why hair drug screening is the most challenging practice to execute.

Confirmation of any positive Screening results is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives are washed prior to necessary confirmation. The complete laboratory procedure from Accessioning to Confirmation is conducted under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can identify drug use for up to 90 days, unlike urine tests that offer a shorter detection window.
• Hard to manipulate: It is extremely challenging to alter a hair drug test, resulting in more precise outcomes.
• Reveals historical usage: It can illustrate a pattern of substance use over time, not merely recent consumption.

Limitations:

• Cannot identify recent use: It normally takes 5-7 days for substances to be present in hair.
• Expense: Hair drug assessments are generally pricier than other testing approaches.
• Result variations: Elements like hair color and individual hair growth differences can influence the concentration of drug metabolites in the hair.

Note: Although frequently labeled as "hair follicle tests", the analysis actually examines the hair strand, not the follicle beneath the skin.
