Accredited Drug Testing provides comprehensive hair follicle drug testing services in Bell Hill, Washington. Whether you're looking for a hair drug or alcohol test, we specialize in hair analysis, with centers nationwide ready to perform these exams.

In recent times, hair follicle drug tests have become more prevalent for drug screening. Numerous employers, judicial systems, and Substance Abuse experts prefer hair tests over traditional urine tests. These tests are favored by employers enforcing zero-tolerance policies, courts, and probation officers. The key advantage of hair follicle testing is its extended detection window, generally up to 90 days, with a supervised collection, and they're nearly foolproof. That said, urine tests remain most accurate for detecting recent drug use within the last 5 days.

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair offers an extensive timeline of alcohol and drug usage by encapsulating biomarkers in the hair's growing strands. When taken near the scalp, hair can offer up to a 3-month detection period for alcohol and drugs. Hair is straightforward to gather, relatively tamper-resistant, and simple to transport.
A 1.5-inch segment of roughly 200 hair strands (approximately the size of a #2 pencil) closest to the scalp provides 100mg of hair, which is the preferred quantity for analysis. For EtG, additional tests, and/or panels exceeding 10, 150mg of the specimen is advised. It's advisable to measure the sample using a precision scale, like a jeweler's scale. In the event scalp hair is unavailable, a comparable amount of body hair can be collected. References to head hair specifically mean scalp hair. Body hair refers to any other hair types (such as facial or axillary).
Process Overview
There are four primary stages in the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial handling of a sample into a lab's system. This process ensures the sample was correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any extraneous data entry needed in absence of an electronic chain of custody system.
Screening consists of a preliminary examination for substances of abuse. Though Screening is an economical way to exclude drug use in most samples, a positive result requires Confirmation to be valid in legal settings. Presumptively positive samples in Screening require further confirmation.
If a sample is flagged as presumptively positive during Screening, more hair is taken from the original specimen for Extraction. At this stage, drugs are separated from hair at concentrations lower than other techniques (such as urine or oral fluid), which makes hair drug testing one of the most challenging methods.
Confirmation for any positive screen is performed using GC/MS, GC/MS/MS or LC/MS/MS. All presumptively positive samples undergo washing before Confirmation if required. The entire lab process from Accessioning to Confirmation is assessed both by the CAP (College of American Pathologists) Hair designation and accredited to ISO/IEC 17025 standards.
