Accredited Drug Testing offers comprehensive hair follicle drug testing services in Cary, Illinois. Specializing in hair and alcohol testing, we have facilities nationwide, including Cary, to conduct hair tests. Typically, 1.5 to 2 inches of hair from the head or body is required. Hair samples can be tested for drugs, alcohol/ETG, and other specific needs.
In recent times, hair follicle drug testing has become increasingly common for drug screening. It is often preferred by employers, courts, and substance abuse professionals over traditional urine tests. This method is favored by those with strict no-drug policies, including courts and parole authorities. One of the significant advantages is its longer detection period of up to 90 days, which, along with direct observation collection, makes it nearly foolproof. However, for detecting recent drug use within five days, urine tests maintain accuracy.

The utilization of hair testing has emerged as an effective method for detecting drug and alcohol consumption. Hair retains a long-term record of drugs and alcohol use by incorporating biomarkers within the fibers of the developing hair strands. Hair collected near the scalp can provide a detection window for alcohol and drugs lasting up to roughly 90 days. This testing method is straightforward to collect, somewhat resistant to tampering, and simple to transport.
A sample measuring 1.5 inches, consisting of approximately 200 hair strands (similar in size to a #2 pencil) taken closest to the scalp, yields 100mg, which is the optimal sample amount for both screening and corroboration. For tests like EtG, add-ons, or the ones exceeding 10 panels, a specimen quantity of 150mg is advised. It is best to weigh the specimen with a jeweler's scale. Should scalp hair be unavailable, an equivalent quantity of body hair can be collected. When mentioning head hair, it refers exclusively to scalp hair. Body hair encompasses all other types of hair (e.g., facial, axillary).
Process Overview
The four primary stages in the laboratory processing of drug test results encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial handling of a sample into a laboratory's system. This step involves confirming that the sample is properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and performing supplemental data entry not covered by an electronic chain of custody system.
Screening involves a preliminary rapid check for substances of abuse. While it is a cost-efficient means to rule out drug use in most samples, a positive screen requires confirmation for legal admissibility. Any samples with a presumptive positive result in Screening must undergo secondary validation.
If a sample shows a presumptive positive result during the Screening stage, additional hair is extracted from the initial sample and prepared for Extraction. At this stage, drugs are extracted from hair at a notably lower concentration than with other methods (like urine or oral fluid), making hair drug testing one of the most challenging methodologies to conduct.
Confirmation of any positive result from screening is achieved using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptively positive samples undergo washing before confirmation as necessary. The full laboratory procedure from Accessioning to Confirmation undergoes review in accordance with both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
