Hair Follicle Drug Testing - Marshfield, WI

What it is, How it works

Hair analysis is recognized as an effective method to identify drug and alcohol usage. Hair captures a prolonged history of substances by encapsulating biomarkers within the strands as they grow. When taken near the scalp, hair samples can offer a detection period of up to 90 days for alcohol and drugs. The collection is straightforward, challenging to tamper with, and easy to transport.

A 1.5-inch segment of approximately 200 hairs (similar in circumference to a #2 pencil) nearest the scalp provides 100mg of hair, which is ideal for analysis. For EtG, additional panels, or tests above 10 panels, 150mg of hair is advised. It is suggested to measure this on a jeweler's scale. If head hair isn't available, an equivalent amount of body hair can be used. "Head hair" specifically refers to scalp hair. "Body hair" includes other hair types (such as facial or axillary).

Process Overview

The drug test result processing in the lab consists of four main stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first stage involving the lab intake of samples. It ensures proper sealing and shipping, assigns a LAN (Laboratory Accessioning Number), and completes any required extra data entry absent in electronic custody chains.

Screening is a preliminary evaluation for drug presence. Although economical for negating drug use in most cases, a positive screen must be verified for legal admissibility. Presumptively positive samples in Screening require further confirmation.

If Screening indicates a positive result, additional hair is extracted for further analysis in the Extraction phase. Here, the drug is isolated at lower concentrations than other methods (such as urine or oral fluids), making hair drug testing a complex technique to execute.

Confirmation follows for any positive screening outcomes using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives undergo washing if necessary before confirmation. The entire lab procedure from Accessioning to Confirmation is audited 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 use for up to 90 days, unlike urine tests that have a shorter detection span.
• Challenging to falsify: Altering a hair drug test is difficult, enhancing accuracy.
• Reflects historical patterns: It reveals drug use patterns over time, not only recent consumption.

Limitations:

• Cannot identify recent usage: Drugs are detectable in hair only after 5-7 days.
• Cost: Hair drug tests typically cost more than other methods.
• Result variability: Hair color and individual hair growth differences can influence drug metabolite levels.

Note: Commonly called "hair follicle tests", the analysis is performed on the hair strand, not the follicle beneath the scalp.
