Hair Follicle Drug Testing - Walnut Hill, IL

What it is, How it works

Hair assessment is increasingly recognized as an effective method for identifying substance and alcohol consumption. Hair captures a historical record of alcohol and other drugs by embedding biomarkers within the strands of the growing hair. When gathered near the scalp, hair can indicate drug and alcohol use for up to around 90 days. Collection of hair samples is straightforward, relatively resistant to tampering, and easy to transport.

A 1.5-inch segment containing roughly 200 hairs (comparable to the thickness of a #2 pencil) near the scalp yields 100mg, which is ideal for both screening and confirmation. For EtG, supplementary, or tests exceeding 10 panels, 150mg of the sample is advised. It's important to measure the sample using a jeweler’s scale. If scalp hair is not accessible, an equivalent volume of body hair can be used. "Head hair" refers strictly to scalp hair, while "body hair" includes all other hair forms (facial, axillary, etc.).

Process Overview

The essential steps in lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a specimen is first inputted into a lab’s system. This involves ensuring the sample was properly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data input absent from an electronic chain of custody system.

Screening is a preliminary rapid assessment for drug abuse. Though Screening is an economical approach to eliminate drug use in most samples, a positive result must be validated to be accepted legally. Samples with presumptive positives in Screening need additional confirmation.

If a sample appears to be positive during the Screening phase, additional hair from the original specimen is prepared for Extraction. This step involves isolating drugs from hair at much lower concentrations than other techniques (ex. urine or oral fluid), highlighting the complexity of hair drug screenings.

Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Any presumably positive samples undergo washing before confirmation if necessary. The comprehensive lab workflow from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection timeframe.
• Resistant to cheating: Cheating a hair drug test is exceptionally difficult, enhancing result accuracy.
• Supplies historical use data: It traces drug usage patterns over time, beyond just recent use.

Limitations:

• Delayed detection for recent use: It takes about 5-7 days for drugs to appear in hair.
• Expense: Hair drug tests typically cost more than alternate testing methods.
• Result variability: Elements like hair color and personal hair growth differences can influence the drug metabolite concentration in hair.

Note: While commonly called "hair follicle tests", the procedure examines the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

For detecting drug use, hair follicle testing objectively outshines urine testing in Walnut Hill, IL. Hair tests provide longer detection periods, highlighting substance use over three months, unlike the short window of urine tests.
