Accredited Drug Testing offers extensive hair follicle drug tests in Woodbridge, California. For those needing a hair drug or alcohol evaluation, we specialize in hair sampling, with centers across every city nationwide equipped to handle hair tests. Typically, having 1.5 to 2 inches of hair on your head or body is necessary. Hair tests can detect drugs, alcohol/ETG, or other specialized testing options.
Recently, hair follicle drug tests have increasingly been used in drug testing practices. Employers, courts, and Substance Abuse experts often require a hair test over a standard urine analysis. Hair follicle tests are preferred by employers supportive of zero-tolerance drug policies, judicial courts, and those on probation. Their main advantage lies in a longer drug detection window, usually up to 90 days, through an observed process that is almost impossible to deceive. However, urine tests remain the most precise method for detecting drug use within the previous 5 days.

Hair testing is increasingly recognized as an effective means for identifying drug and alcohol use. Hair captures a long-term record of substance consumption by embedding biomarkers within the strands as they grow. When hair is collected near the scalp, it can offer a detection timeline of up to roughly three months for various substances. The process of collecting hair is straightforward, challenging to tamper with, and simple to transport.
A hair segment measuring 1.5 inches with around 200 strands (approximately the girth of a #2 pencil) nearest to the scalp yields 100mg, the volume optimal for both initial screening and verification. For EtG, enhancements, or tests exceeding 10 panels, 150mg is ADVISED. Using a jeweler’s scale is suggested for weighing the sample. Should scalp hair be unobtainable, an equivalent mass of body hair can be used. "Head hair" specifically refers to scalp hair in these contexts, whereas "body hair" encompasses all other varieties such as facial and axillary hair.
Process Overview
The key phases in processing a drug test result in a lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning takes care of the initial sample processing within a lab’s system, making sure the sample is properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and entering any extra data not covered by an electronic chain of custody system.
Screening is about a preliminary fast analysis for substances of abuse. Even though Screening is economical for negating drug use in most cases, a positive result demands confirmation to stand in legal proceedings. Samples that screen positive presumptively require a follow-up confirmation.
Should a sample yield a presumptive positive during Screening, additional hair is taken from the original specimen and readied for Extraction. In this stage, substances are extracted from hair at considerably lower levels than with other methods (e.g., urine or saliva), highlighting the challenge of hair drug screening.
Confirmation of any positive screen involves techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if needed. The full laboratory sequence, from Accessioning to Confirmation, is examined under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 benchmarks.
