Accredited Drug Testing provides comprehensive hair follicle drug screening services in McFarland, California. Whether it's necessary to conduct a hair drug or alcohol test, Accredited Drug Testing focuses on hair analysis and offers testing locations throughout the nation to accommodate such needs. Ideally, 1.5 to 2 inches of scalp or body hair is required to conduct most tests. These examinations can discern drugs, alcohol/ETG, or be tailored for specific testing requirements.
Hair follicle drug tests have become increasingly prevalent in modern drug testing processes, supplanting traditional urine tests. With the shift, more employers, judicial systems, and substance abuse experts insist on this method. Hair drug tests appeal to employers with strict anti-drug mandates, legal bodies, and those overseeing probation. Among the benefits of hair follicle testing is its extended detection span—lasting up to 90 days—and its stringent supervised collection protocol, making it hard to manipulate. However, for identifying recent drug use within the past five days, urine tests still hold the highest accuracy.

Hair analysis is regarded as an effective means for identifying substance use, capturing enduring markers of alcohol and drugs in strands as they grow. When clipped near the scalp, this method can detect usage of alcohol and drugs for a duration of up to three months. The collection process is straightforward, with reduced risk of tampering, and shipping is convenient.
A sample of 1.5 inches from around 200 strands (equivalent in size to a #2 pencil) closest to the scalp yields 100mg of hair, optimal for testing. For EtG, additional testing, or panels beyond ten, 150mg is preferable. A jeweler’s scale is recommended for precise weighing. If head hair is not accessible, an equivalent amount of body hair can be used. The term "head hair" denotes scalp hair, whereas "body hair" covers all other types, including facial or axillary.
Process Overview
The core phases in processing drug test results in a lab are Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, samples are integrated into the lab system with steps to confirm the integrity of sealing and shipment, the assignment of a unique LAN (Laboratory Accessioning Number), and performing any residual data entry not managed by an electronic custody system.
Screening provides an initial rapid assessment for substance abuse. While cost-efficient for eliminating drug use in most samples, a positive result must undergo further validation to be recognized legally. Samples flagged as presumptive positives during Screening require additional confirmation.
For samples indicated as presumptive positive during Screening, additional hair is extracted from the original sample for the Extraction phase. Here, traces of drugs are removed from hair at lower concentrations compared to other tests like urine or saliva, adding complexity to hair drug screening.
To verify positive screening findings, methods such as GC/MS, GC/MS/MS, or LC/MS/MS are utilized. Samples are washed prior to confirmation where necessary. Each process step from Accessioning to Confirmation is scrutinized by CAP (College of American Pathologists) in line with the Hair rules and ISO / IEC 17025 accreditation criteria.

Limitations:
Note: Though often dubbed "hair follicle tests", the evaluation is conducted on the hair strand itself, not on the follicle beneath the scalp.
