Accredited Drug Testing offers comprehensive hair drug testing services in Guerneville, California. If you're in need of a hair drug or alcohol screening, Accredited Drug Testing is an expert in this field and provides testing centers across all major cities nationwide. For a test, typically 1.5 to 2 inches of hair from the crown or an alternative body part is required. Hair tests can reveal drugs, alcohol/ETG, or other specialized options.
Recently, drug testing methods have increasingly embraced hair follicle testing over traditional urine tests. Numerous employers, judicial systems, and Substance Abuse professionals are favoring this approach. Hair follicle tests are favored by zero-tolerance employers, courts, and probation officers. The key advantage is a prolonged detection window, usually up to 90 days, collected under supervision, making tampering nearly impossible. Still, for recent drug use within the past 5 days, urine tests remain the most reliable.

Hair analysis is widely recognized as an effective method for detecting drug and alcohol consumption. It chronicles long-term alcohol and drug use by embedding biomarkers within the strands of growing hair. When obtained near the scalp, hair can reveal a history of up to roughly three months for alcohol and drug usage. The collection process for hair is straightforward, hard to tamper with, and convenient for transportation.
A sample measuring 1.5 inches, comprising around 200 hair strands (approximating the girth of a #2 pencil), taken close to the scalp, will weigh about 100mg, which is ideal for screening and confirmation. For assessments involving EtG add-ons and/or tests exceeding 10 panels, a specimen weighing 150mg is advised. It is advisable to use a jeweler's scale for accurate weighing. Should scalp hair be unavailable, equivalent amounts of body hair can be utilized. "Head hair" pertains specifically to scalp hair, whereas "body hair" includes all other varieties (like facial, axillary, etc.).
Process Overview
Drug test outcomes in a laboratory follow four primary steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is first processed into a laboratory's system. This step verifies that the sample was properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry not captured by an electronic chain of custody system.
Screening represents the initial rapid assessment for substances of abuse. Although Screening is a cost-effective method to eliminate drug use in most samples, a positive result must be confirmed to be legally defensible. Samples that yield a presumptive positive in Screening demand subsequent confirmation.
Should a sample test positive at the Screening stage, additional hair from the initial batch is prepared for Extraction. This process extracts drugs from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), explaining why hair drug screening is among the most challenging methodologies.
Confirmation of any positively screened sample is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives undergo washing prior to confirmation as required. The complete procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and complies with the ISO / IEC 17025 accreditation standards.

Note: Commonly termed "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp.
