Located in Placerville, California, Accredited Drug Testing provides comprehensive hair follicle drug assessments. With expertise in hair and alcohol testing, our centers operate across the nation ready for hair sample collection. Typically, 1.5 to 2 inches of hair from the scalp or body is needed. Various substances including drugs and alcohol/ETG can be screened using hair tests.
Hair follicle tests have increasingly become a preferred method for drug assessment in recent years. Employers, judicial systems, and substance abuse professionals often opt for hair tests over urine tests. They are chosen by those with strict no-drug policies due to the extended detection period, up to 90 days, secured by supervised collection. To detect drug use within the past 5 days, however, urine tests remain more precise.

Hair analysis is recognized as an effective method for identifying alcohol and drug consumption. Hair captures a historical record of substance use by embedding biomarkers within its strands as it grows. When taken from near the scalp, it offers about a 90-day scope of detection for both alcohol and drugs. Hair is straightforward to gather, tougher to tamper with, and convenient to transport.
A segment of hair measuring 1.5 inches, with approximately 200 strands (comparable to a #2 pencil), close to the scalp provides 100mg, which is the optimal amount for testing and validation. For EtG tests, additional parameters, or tests exceeding ten panels, a collection of 150mg is advised. We suggest using a jeweler's scale to weigh the hair sample. If scalp hair is not present, a proportional amount of body hair can be used. By head hair, we mean only the hair on the scalp. Other hair types such as facial or axillary hair are termed as body hair.
Process Overview
The drug test laboratory process encompasses these primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the act of logging a sample into a lab's database. This process verifies the sample's seal and proper delivery, assigns a Laboratory Accessioning Number (LAN) randomly, and completes additional details not covered by an electronic chain of custody record.
Screening is a preliminary assessment to identify the presence of abusive drugs. It serves as an economical method to dismiss drug use in most samples, yet any positive results require confirmation to be legally admissible. Samples with presumptive positive results from screening mandate further verification.
Should a sample test presumptively positive during Screening, additional hair is extracted from the sample for the Extraction phase. This stage isolates drugs from hair at significantly lower levels than other testing methods like urine or oral fluid samples, which contributes to the complexity of hair drug testing.
For positive results from Screening, a Confirmation is performed using analytical techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Any samples testing positive are cleansed prior to confirmation as necessary. From Accessioning through to Confirmation, the complete lab process is audited under the CAP (College of American Pathologists) Hair guidelines alongside ISO/IEC 17025 accreditation.
