Hair Follicle Drug Testing - Foley, MN

What it is, How it works

Hair testing is increasingly recognized as an effective means for detecting drug and alcohol usage. The hair retains a historical record of substances by capturing biomarkers within the fibers of its growing strands. Collecting hair near the scalp offers an estimated detection period of up to 3 months for alcohol and other drugs. Collecting hair is straightforward, tampering is quite hard, and it's simple to transport.

A 1.5-inch section comprising roughly 200 hair strands (approximately the thickness of a #2 pencil) from the scalp delivers 100mg of hair, which is the preferred sample for both screening and confirmation. For EtG, additional tests, or analyses exceeding 10 panels, 150mg of the sample is advisable. It's suggested to measure the sample's weight using a jeweler’s scale. If there's no scalp hair available, an equivalent amount of body hair can be used. When we mention head hair, we specifically mean scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

There are four key steps in the lab processing of a drug testing result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step where a sample is processed into a lab’s system. This procedure ensures that the sample was correctly sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any additional data entry not captured by an electronic chain of custody system.

Screening is a preliminary rapid assessment for drug abuse. Though Screening is a budget-friendly approach for excluding drug usage on most samples, any positive screen must be confirmed for court acceptability. Samples with a presumptive positive Screening result necessitate further confirmation.

Should a sample show a presumptive positive during Screening, extra hair is extracted from the initial sample for Extraction. During Extraction, drugs are isolated from hair at concentrations much lower than those found in alternative approaches (e.g., urine or oral fluid), which makes hair drug testing one of the most challenging methodologies to execute.

Confirming positive screening outcomes is done through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives are cleansed before confirmation as required. The comprehensive laboratory procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug usage up to 90 days, unlike urine tests which have a shorter detection duration.
• Resistance to tampering: It's exceedingly difficult to manipulate a hair drug test, ensuring greater result accuracy.
• Delivers historical insight: It can trace a pattern of drug use over time and not just recent consumption.

Limitations:

• Inability to detect recent usage: Detection of drugs in hair takes approximately 5-7 days.
• Expense: Hair drug tests generally cost more than other drug testing methods.
• Result variability: Elements like hair color and individual growth rates can impact the level of drug metabolites in the hair.

Note: Commonly known as "hair follicle tests", the analysis targets the hair strand rather than the follicle under the scalp.
