Located in Durham, CA, Accredited Drug Testing offers comprehensive hair follicle testing services. For those in need of drug or alcohol examination through hair analysis, we specialize in these services with nationwide testing facilities available. It’s typically required to have 1.5-2 inches of hair from the scalp or body for testing. This method allows for the detection of drugs, alcohol/ETG, or other specific substances.
Over recent years, hair follicle drug tests have become a staple in drug testing procedures. They are increasingly chosen by employers, judicial bodies, and substance counselors over urine tests. Such tests aid employers with strict drug policies, judicial mandates, and probation monitoring due to their extensive detection timeframe which extends up to 90 days. While virtually foolproof, they fall short of urine tests for very recent drug use within 5 days.

Hair analysis is increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair offers an extended record of alcohol and other substances by capturing biomarkers within the fibers of the growing hair. When taken near the scalp, hair can yield a detection window of up to roughly 3 months for alcohol and other substances. Hair collection is straightforward, difficult to tamper with, and simple to send.
A 1.5-inch portion of approximately 200 hair strands (similar in size to a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal amount for analysis and validation. For EtG, additional tests, and/or tests exceeding 10 panels, it is advised to have 150mg of the sample. Utilizing a jeweler’s scale for measuring the sample is advised. If scalp hair is not available, a comparable quantity of body hair can be gathered. When mentioning head hair, we specifically mean scalp hair. Body hair covers all other hair varieties (facial, axillary, etc.).
Process Overview
The laboratory process for a drug test result consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary intake of a sample into a laboratory’s database. This comprises verifying the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any remaining data entry not covered by an electronic chain of custody system.
Screening is a preliminary rapid assessment for substance abuse. While being a cost-efficient approach to eliminate drug usage for most samples, a positive screen necessitates confirmation for legal admissibility. Samples deemed presumptively positive in Screening require a follow-up confirmation.
If a sample is deemed presumptively positive during Screening, more hair is extracted from the initial sample and readied for Extraction. In this phase, drugs are extracted from hair at a much lower concentration than through other methods (e.g., urine or oral fluid), which is why hair drug screening poses the greatest challenge to execute.
Verification of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are washed before confirmation if necessary. The complete laboratory process, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.
