In Modesto, Illinois, Accredited Drug Testing provides comprehensive hair follicle drug tests. This reliable service offers hair drug or alcohol testing, with nationwide centers ready to conduct these tests. Typically, a hair sample from the crown of your head, requiring 1.5 to 2 inches, is used. Hair tests are thorough, offering analyses for drugs, alcohol/ETG, and other specific testing needs.
Recently, hair follicle testing has become more common in drug testing. Many employers, legal systems, and substance abuse experts prefer it over traditional urine tests. This method benefits zero-tolerance workplaces, legal environments, and those on probation, due to its prolonged drug detection window of up to 90 days, secured through observed collection, and is virtually impossible to manipulate. Nonetheless, urine tests remain most effective for detecting very recent drug use within five days.
* You must register by phone or online to receive your donor pass/registration prior to proceeding to the testing center. You must bring a valid government issued ID along with the registration/barcode number which was sent to you by email.

Hair testing has gained recognition as an effective means for identifying drug and alcohol consumption. Hair captures biomarkers in the strands' fibers, offering a long-term record of alcohol and drug history. When taken near the scalp, hair is capable of providing up to a three-month detection timeline for substances. Collecting hair is straightforward, relatively tamper-proof, and easily transportable.
A sample size of 1.5 inches with around 200 hair strands (equivalent to the thickness of a #2 pencil) taken nearest to the scalp delivers 100mg, which is the optimal quantity for analysis and validation. For tests like EtG and/or those exceeding 10 panels, a 150mg sample is advised. We suggest measuring the sample with a jeweler’s scale. Should scalp hair be unavailable, a comparable quantity of body hair can be used. Head hair specifically refers to scalp offerings, while body hair includes all other sorts (facial, axillary, etc.).
Process Overview
The primary stages in the lab processing of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial stage of integrating a sample into the lab’s processes. This step involves confirming the sample's proper sealing and shipping, issuing a random LAN (Laboratory Accessioning Number), and completing additional data entry if missing from an electronic chain of custody system.
Screening consists of a preliminary assessment for drug presence. Although Screening is an economical method to dismiss drug usage in most samples, a positive result necessitates confirmation for court admissibility. Any presumptively positive results from Screening are subjected to a subsequent confirmation.
Should a sample be presumptively positive in the Screening phase, additional hair is extracted from the primary sample for preparation in the Extraction stage. During this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or saliva), making hair drug testing particularly challenging.
Confirmation of any positive Screening outcomes is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo cleansing before confirmation as required. The complete lab procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
