Accredited Drug Testing provides comprehensive hair follicle drug analysis in Markham, Illinois. For those needing a hair drug or alcohol screening, our expertise lies in hair testing with centers available across all cities nationwide. Generally, 1.5 to 2 inches of hair from the crown or body can be used. Hair tests are employed for drugs, alcohol/ETG, or other personalized options.
Recently, the use of hair follicle drug testing has increased. Employers, courts, and substance abuse professionals often opt for hair tests over standard urine tests. Hair tests are favored by employers with strict drug policies, legal systems, and those on probation. The main advantage of hair testing is a longer drug detection window, lasting up to 90 days, and its collection is observed and difficult to manipulate. However, for drug use in the past 5 days, urine tests remain most accurate.

Hair analysis is recognized as an effective method for detecting the consumption of drugs and alcohol. The fibers of growing hair strands retain biomarkers, offering an extended historical view of substance use. When hair is harvested near the scalp, it provides a detection timeframe of up to roughly three months for substances. Hair collection is straightforward, hard to tamper with, and simple to ship.
A 1.5-inch length comprising roughly 200 hair strands (approximately the size of a #2 pencil) closest to the scalp accumulates 100mg of hair, which is the perfect amount for both screening and confirmation. For EtG, additional testing, and/or panels exceeding 10, a 150mg sample is advisable. It's recommended to gauge the sample's weight with a jeweler’s scale. In the absence of scalp hair, a matching amount of body hair can be used. Reference to head hair pertains strictly to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
Processing a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary entry of a sample into a laboratory’s system. This stage ensures the sample was correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any essential data input not documented by an electronic chain of custody.
Screening executes an initial, expeditious assessment for controlled substance use. While screening provides a cost-efficient means of negating drug use in a large portion of samples, a positive result needs confirmation for legal validity. Any screening-indicated positive samples necessitate secondary verification.
Should a sample test positive during Screening, additional hair is extracted from the original sample for further Extraction. At this juncture, drugs are drawn from hair at notably lower concentrations compared to other methods (e.g., urine or saliva), thus rendering hair drug screening a particularly challenging technique to perfect.
Confirmation of any positive screening is undertaken via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples undergo washing before confirmation if required. The complete laboratory process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation and attests to ISO / IEC 17025 standards.
