Accredited Drug Testing offers comprehensive hair follicle drug tests in Grangeville, California. If you require hair drug or alcohol testing, we specialize in hair analysis and have facilities in all cities nationwide to conduct a hair test. Typically, 1.5 to 2 inches of hair are needed from the head or body. Hair tests can screen for drugs, alcohol/ETG, among other specialized options.
Recently, hair follicle drug testing has become a preferred method for conducting drug tests. Employers, courts, and substance abuse experts often choose this over traditional urine testing. Hair follicle tests are selected by organizations with zero-tolerance policies and for individuals on probation due to their longer drug use detection window, typically up to 90 days, reducing the likelihood of tampering. However, for drug use detection within the last 5 days, urine tests remain optimal.
* 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 analysis is increasingly recognized as a significant method for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and drugs by embedding biomarkers in the strands of developing hair. When taken near the scalp, hair can offer up to a roughly three-month period for detecting alcohol and drugs. Hair is easy to retrieve, relatively challenging to tamper with, and convenient to transport.
A 1.5-inch length consisting of about 200 hair strands (comparable to a #2 pencil) proximal to the scalp will yield 100mg of hair, which is the optimal amount for both screening and verification. For EtG, supplementary tests, or assessments exceeding 10 panels, a specimen of 150mg is suggested. We advise measuring the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair might be obtained. When talking about head hair, we indicate scalp hair specifically. Body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The critical phases in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial registration of a sample in a laboratory’s system. This step includes confirming that the specimen was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry absent from an electronic chain of custody platform.
Screening constitutes a preliminary swift assessment for drugs. Although Screening is an economical means to rule out drug presence in most specimens, a positive screen requires confirmation for legal validity. Samples presuming positive in Screening necessitate a subsequent validation.
If a sample is tentatively positive in the Screening phase, additional hair is extracted from the original collection for Extraction. Here, drugs are derived from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing the most intricate technique to execute.
Validation of any positive screening result involves GC/MS, GC/MS/MS, or LC/MS/MS. All suspected positive samples are cleansed before confirmation if necessary. The entire lab sequence from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair label and the certification to ISO / IEC 17025 standards.
