Hair Follicle Drug Testing - Lodi, WI

What it is, How it works

Hair testing is regarded as an effective method for detecting drug and alcohol consumption. Hair captures a long-term record of substance usage by embedding biomarkers within the strands as they grow. Hair harvested near the scalp can provide a detection window of up to approximately three months for drugs and alcohol. Collection is straightforward, tampering is challenging, and shipping is uncomplicated.

A 1.5-inch section, containing around 200 hair strands—roughly the thickness of a #2 pencil—from near the scalp will yield 100mg, which is ideal for screening and confirmation. For EtG, additional tests, or more than 10 panels, 150mg is advisable. Using a jeweler’s scale for weighing is recommended. In the absence of head hair, an equivalent amount of body hair may be used. "Head hair" specifies scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory analysis of a drug test result consists of four main stages: Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, a sample undergoes the initial integration into a laboratory system. This stage ensures the sample is sealed correctly and shipped securely, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry not covered by an electronic chain of custody system.

Screening is an initial rapid examination for drugs of abuse. While Screening is a cost-efficient solution for eliminating drug usage in most samples, any detected positives must be confirmed for court admissibility. Hence, presumptively positive samples necessitate secondary confirmation.

Should a sample test presumptively positive during Screening, additional hair is extracted from the initial specimen for the Extraction stage. Drugs are then extracted from hair at a lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.

Confirmation for any positive Screening result is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation as required. The procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests can trace drug use for up to 90 days, surpassing urine tests with a shorter window.
• Difficult to manipulate: Hair drug tests are nearly impossible to falsify, ensuring more reliable outcomes.
• Historical usage insight: These tests provide patterns of drug consumption over time, rather than only recent activity.

Limitations:

• Inability to detect recent use: Drugs take approximately 5-7 days to become detectable in hair.
• Expense: Hair drug tests usually cost more than other testing methods.
• Result variability: Influences such as hair color and individual growth rates can alter the concentration of drug metabolites in hair.

Note: Although often termed "hair follicle tests", the analysis targets the hair strand, not the follicle beneath the scalp
