Accredited Drug Testing provides comprehensive hair follicle drug testing services in La Mesa, California. If you require testing for drugs or alcohol, our specialty in hair testing is unmatched, with facilities located throughout the entire country that offer hair testing services. Typically, 1.5 to 2 inches of hair from the crown of your head or other body areas are required for analysis. Hair tests are available for detecting drugs, alcohol/ETG, and other personalized testing solutions.
In recent times, the favored approach for drug testing is increasingly using hair follicle analysis. A growing number of businesses, legal systems, and addiction specialists require hair drug tests in lieu of traditional urine exams. Hair follicle drug tests are ideal for employers with zero-tolerance drug policies, judicial systems, and individuals under probation. The key advantage of these tests is their extended detection duration, typically up to 90 days, with a robust, monitored collection process, making evasion nearly impractical. However, for assessing drug use within the last 5 days, urine tests remain unparalleled in precision.

Hair testing is now acknowledged as an effective means for detecting drug and alcohol use. Hair captures a historical record of alcohol and drug consumption by containing biomarkers within the fibers of the growing strand. When procured near the scalp, hair can offer up to a roughly 3-month detection scope for alcohol and drugs. Gathering hair is straightforward, moderately hard to tamper with, and simple to transport.
A sample measuring 1.5 inches, containing about 200 strands (approximately the thickness of a #2 pencil) closest to the scalp, yields 100mg of hair, which is the optimal quantity for analysis and verification. For EtG, additional tests, and/or those beyond 10 panels, 150mg of the sample is advised. Utilizing a jeweler's scale is suggested to weigh the specimen. Should scalp hair be inaccessible, an equivalent quantity of body hair may be obtained. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four fundamental stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial intake of a sample into a lab's system. This process includes ensuring the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and filling in any additional data not already captured by an electronic chain of custody system.
Screening entails an initial rapid assessment for drugs of misuse. While Screening provides a cost-efficient method to exclude drug usage for most specimens, any positive screen must be validated to stand up in legal settings. Specimens that test presumptively positive during Screening must undergo a secondary confirmation.
If a specimen tests presumptively positive during the Screening phase, more hair is extracted from the primary sample and readied for Extraction. In this phase, drugs are extracted from hair at a significantly lower concentration than in other methods (e.g., urine or oral fluid), underscoring why hair drug screening is the most challenging methodology to perform.
Confirmation of any positive screening finding is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation when necessary. The overall laboratory process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
