Hair Follicle Drug Testing - Cottage Grove, WI

What it is, How it works

Hair analysis is increasingly recognized as a potent method for identifying drug and alcohol consumption. Hair captures a historical record of substance use by embedding biomarkers within the hair strand as it grows. A sample taken near the scalp can reflect a detection span of up to three months for substances such as alcohol and drugs. The collection process for hair is straightforward, challenging to tamper with, and convenient to mail.

A 1.5-inch section comprising around 200 strands (approximately the thickness of a #2 pencil) from the scalp can yield 100mg of hair, which is an optimal quantity for both screening and confirmation. For EtG, enhancements, or tests exceeding ten panels, a 150mg sample is advisable. Utilizing a jeweler’s scale for weighing the sample is suggested. If scalp hair cannot be obtained, similar quantities of body hair can be utilized. When mentioning head hair, it pertains solely to scalp hair. Body hair encompasses alternative hair types (facial, axillary, etc.).

Process Overview

The drug testing laboratory process encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initial stage, incorporating the sample into the laboratory's system, ensuring proper sealing and shipping, generating a unique LAN (Laboratory Accessioning Number), and completing any missing data entry not provided by an electronic chain of custody.

Screening delivers an initial rapid evaluation for substances of abuse. While cost-effective for excluding drug use in most specimens, a positive screening result requires confirmation before legal admissibility. Specimens with presumptive positive results from Screening require further verification.

Should a specimen show a presumptive positive in Screening, additional hair is collected from the initial sample for the Extraction stage. During this stage, substances are extracted from hair at significantly lower concentrations compared to methodologies like urine or oral fluid testing, which is why hair testing is the most challenging to execute.

Confirmation of positive results from Screening is conducted through methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All suspect samples undergo washing before confirmation as necessary. The entire lab procedure from Accessioning to Confirmation is evaluated in accordance with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can trace drug use for up to 90 days, unlike urine tests which have a more limited detection period.
• Cheating deterrence: Hair drug testing is notably challenging to deceive, enhancing the reliability of the outcomes.
• Historical insight: It offers an overview of drug consumption patterns over time, not solely recent use.

Limitations:

• Inability to detect immediate use: It generally takes 5-7 days for substances to emerge in hair samples.
• Expense: Hair drug tests tend to be pricier than other testing techniques.
• Result variability: Factors like hair color and individual differences in hair growth may impact drug metabolite concentrations in hair.

Note: Frequently termed "hair follicle tests", these assessments actually examine the hair strand itself, not the follicle beneath the scalp.
