Accredited Drug Testing offers extensive hair follicle drug examinations throughout San Mateo, California. Whenever a hair-based alcohol or drug analysis is needed, Accredited Drug Testing provides specialized hair assessments, with facilities available across cities nationwide for administering these tests. A length of 1.5 to 2 inches on your scalp or body is generally necessary to conduct these tests. Hair analyses can identify drugs, alcohol/ETG, or other specific requirements.
Over recent years, reliance on hair follicle drug analyses has surged in drug testing procedures. Numerous employers, judicial bodies, and professionals in Substance Abuse are opting for hair drug assessments over normal urine analyses. Organizations with zero-tolerance drug guidelines, courts, and probationary instances utilize hair follicle tests. The key advantage is the prolonged detection window for drug use, lasting up to 90 days, performed under observation, and nearly tamper-proof. However, for detecting use within the past 5 days, urine tests remain the benchmark.

Hair assessments have gained recognition as an effective method for identifying drug and alcohol consumption. By encapsulating biomarkers within the strands, hair offers a comprehensive timeline of substance use. When collected near the scalp, hair can reveal a detection period of up to 90 days for alcohol and drugs. It is straightforward to obtain, reasonably tamper-resistant, and simple to transport.
A sample measuring 1.5 inches , consisting of around 200 hair strands (equivalent to #2 pencil thickness) nearest to the scalp, yields approximately 100mg, which is ideal for evaluation and validation. For EtG add-ons or tests exceeding 10 panels, 150mg is advised. Using a jeweler's scale for precision is suggested. If scalp hair is absent, an equivalent amount of body hair can be gathered. Head hair specifically refers to scalp hair, while body hair includes all other types (facial, axillary, etc.).
Process Overview
The quartet of critical steps in lab processing of a drug test result includes Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into the lab's framework. This step verifies proper sealing and shipment of the sample, assigns a unique LAN (Laboratory Accessioning Number), and completes any missing entries not captured by an electronic chain of custody system.
Screening is a preliminary examination for abuse substances. Though cost-effective in excluding drug presence in most samples, a positive screen must be corroborated for legal admissibility. Presumptive positive samples from Screening necessitate additional confirmation.
When a sample is presumptively positive during Screening, additional hair is extracted from the initial sample for the Extraction process. Here, drugs are extracted from hair at considerably lower concentrations compared to other methods (e.g., urine or oral fluid), presenting challenges in hair drug testing execution.
Confirmation of positive Screening results employs GC/MS, GC/MS/MS, or LC/MS/MS. Samples presumptively positive are cleansed before confirmation as required. The comprehensive laboratory process, from Accessioning to Confirmation, is subjected to scrutiny under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
