Hair Follicle Drug Testing - Willow Hill, IL

What it is, How it works

Hair testing is recognized as an effective means for identifying drug and alcohol usage. Through capturing biomarkers within the fibers of hair strands, hair reveals a prolonged record of alcohol and other drugs. When sampled near the scalp, hair can offer around a three-month detection span for substances. Hair is easy to gather, tough to alter, and straightforward to transport.

A 1.5-inch section of about 200 hairs (comparable to a #2 pencil) nearest to the scalp yields 100mg of hair, which is the ideal sample size for both initial and confirmatory testing. For EtG, additional tests, and/or those surpassing 10 panels, 150mg of hair is suggested. We advise using a jeweler's scale to weigh the sample. If there’s no scalp hair, an equivalent amount of body hair should be acquired. When mentioning head hair, we mean scalp hair exclusively. Body hair refers to all other kinds (facial, axillary, etc.).

Process Overview

The primary stages in processing a drug test in a lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial handling of a sample within the lab's system. This step ensures the sample was properly sealed and dispatched, assigns an arbitrary LAN (Laboratory Accessioning Number), and carries out any supplementary data input not covered by an electronic chain of custody system.

Screening performs a preliminary fast check for drug abuse. Although Screening is a budget-friendly approach to dismiss drug use in most samples, any positive screen needs verification to be considered legally valid. Samples testing presumptively positive during Screening require subsequent validation.

In cases where a sample tests presumptively positive at the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. During Extraction, drugs are withdrawn from hair at significantly lower concentrations than other methods (e.g., urine or saliva), making hair drug testing the most complex method to conduct.

Confirmation of positive screening results is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens undergo washing before confirmation if needed. The complete lab process from Accessioning through Confirmation is conducted under both the CAP (College of American Pathologists) Hair category and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug consumption for up to 90 days, whereas urine tests offer a shorter detection period.
• Hard to manipulate: Tampering with a hair drug test is considerably challenging, enhancing result accuracy.
• Historical insights: It reveals patterns of drug intake over time, not just recent consumption.

Limitations:

• Lacks recent use detection: It generally takes 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug assessments tend to be pricier compared to alternative testing methods.
• Result variability: Elements like hair color and personal hair growth differences can impact the concentration of drug residues in hair.

Note: Though often termed "hair follicle tests", the actual analysis is performed on the hair strand, not the hair follicle beneath the scalp
