Located in Greenfield, Illinois, Accredited Drug Testing offers comprehensive hair follicle tests for detecting substances. Whether it’s for drugs or alcohol, our specialty lies in precise hair testing, boasting nationwide centers capable of conducting these evaluations. Typically, 1.5 to 2 inches of hair from the scalp or body is necessary. This type of testing can identify drugs, alcohol/ETG, or be customized for specific needs.
Recently, hair follicle drug tests are more frequently used, surpassing the traditional urine tests. Entities like employers, judicial bodies, and substance abuse experts prefer them for their stringent no-drug policies. The advantage lies in its longer detection window of up to 90 days, combined with the difficulty to manipulate samples. Yet, urine tests hold accuracy for recent usage within a 5-day span.

Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair retains a detailed history of alcohol and drug intake by embedding biomarkers within the fibers of the growing strand. If gathered near the scalp, hair can offer a detection timeframe of up to around three months for alcohol and other drugs. The collection process is straightforward, it’s challenging to tamper with, and it's easy to transport.
A 1.5-inch section of about 200 hair strands (comparable to the width of a #2 pencil) close to the scalp yields 100mg, the optimal amount for both screening and confirmation. For EtG, additional tests, and/or panels exceeding ten, it's suggested to gather 150mg of the hair. We recommend measuring the sample using a jeweler’s scale. If scalp hair is unavailable, body hair of an equivalent measure may be taken. When mentioning head hair, we are specifically referring to scalp hair. Body hair refers to hair from other regions (facial, axillary, and so on).
Process Overview
The lab processing of a drug test result follows four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial introduction of a sample into a lab’s system. This process involves checking that the sample is sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and performing any additional data input not covered by an electronic chain of custody.
Screening consists of a preliminary and rapid check for substances of abuse. Although Screening is a cost-efficient method for eliminating drug use in most samples, any positive result must be confirmed to hold up in court. Samples that show a presumptive positive result in Screening require further confirmation.
If a sample exhibits a presumptive positive during Screening, more hair is extracted from the original sample for Extraction. In this phase, drugs are isolated from hair at much lower concentrations than in other methods (such as urine or oral fluid), highlighting hair drug analysis as the most challenging technique to execute.
Confirmation regarding any positive Screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are cleansed as necessary. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the licensing to ISO / IEC 17025 benchmarks.
Advantages of hair drug testing:
Limitations:
Note: While often called "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.
