Accredited Drug Testing offers comprehensive hair follicle drug testing in Delhi, California. For those requiring a hair drug or alcohol test, Accredited Drug Testing is the expert in hair testing, with testing centers located across the nation capable of executing a hair test. Typically, 1.5 to 2 inches of hair from the scalp or body is required for most tests. Hair tests can assess the presence of drugs, alcohol/ETG, or other personalized hair testing options.
In recent times, the approach to drug testing has increasingly included hair follicle drug testing. Numerous employers, judicial systems, and Substance Abuse professionals now prefer hair drug tests to traditional urine tests. Hair follicle drug tests are chosen by employers enforcing zero-tolerance drug policies, courts, and individuals on probation. The primary advantage of a hair drug test is its extended detection period for drug use, often up to 90 days, with samples collected through an observed process, making it extremely difficult to manipulate. Nevertheless, when identifying drug usage within the past 5 days, urine tests remain the most reliable.

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of these substances by embedding biomarkers within its developing fibers. When collected near the scalp, hair can offer up to an approximate 90-day detection span for substances like alcohol. It is straightforward to gather, hard to tamper with, and convenient to transport.
A 1.5-inch section consisting of approximately 200 hair strands (around the width of a #2 pencil) closest to the scalp provides 100mg of hair, which is the optimal sample size for testing and verification. For EtG, additional tests, and/or panels exceeding 10, 150mg of the sample is advised. Measuring the sample on a jeweler’s scale is recommended. If scalp hair isn’t available, a similar amount of body hair can be used. When discussing head hair, we specifically mean scalp hair. Body hair includes all other types (such as facial and axillary hair).
Process Overview
The four primary steps in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial processing of a sample into a laboratory database. This process ensures that the sample was properly sealed and transported, assigns a random Laboratory Accessioning Number (LAN), and completes any missing data entry not provided by electronic chain of custody systems.
Screening consists of a preliminary assessment for drug presence. While Screening is a cost-effective approach to eliminate drug use in most samples, a favorable screen requires confirmation for legal admissibility. Any samples yielding a presumptive positive during Screening will need follow-up confirmation.
Should a sample yield a presumptive positive during Screening, additional hair is withdrawn from the original sample and prepared for Extraction, where drugs are extracted from hair at significantly lower concentrations than with other techniques (such as urine or oral fluid), making hair drug testing among the most challenging methods to execute.
Confirmation of any positive screen outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation, as required. The entire laboratory procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair criteria alongside the ISO/IEC 17025 accreditation.
