Accredited Drug Testing offers thorough hair follicle drug testing in Pleasant Hill, Washington. If you're in need of a hair drug or alcohol test, we are experts in hair testing and operate testing centers across all cities Nationwide. Typically, 1.5 to 2 inches of hair are necessary from either the head or body. These tests can identify drugs, alcohol/ETG, and offer other tailored hair testing solutions.

Recently, hair follicle drug testing has become more common in the drug testing process. More employers, courts, and Substance Abuse professionals are opting for hair drug tests instead of traditional urine tests. These tests suit employers enforcing zero-tolerance drug policies, judicial systems, and individuals on probation. A significant advantage is the extended detection window of up to 90 days, with supervised sample collection and minimal fraud potential. For detecting drug use within the past five days, urine tests remain highly precise.

What it is, How it works

Hair analysis is regarded as an effective method for identifying drug and alcohol consumption. Hair captures a historical record of substance use by embedding biomarkers within the strands as they grow. If taken near the scalp, hair offers nearly a 3-month detection period for alcohol and drugs. Hair is easy to gather, challenging to tamper with, and simple to transport.

A sample of 1.5 inches, approximately 200 hair strands (similar in size to a #2 pencil) nearest to the scalp, yields 100mg of hair, the ideal for screening and confirmation purposes. For EtG, supplementary tests, and/or tests exceeding 10 panels, 150mg is advised. We advocate for weighing the specimen with a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair may be used. When mentioning head hair, we are specifically indicating scalp hair. Body hair refers to all other types (facial, axillary, etc.).

Process Overview

The primary steps in the laboratory drug test processing are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial sample processing within the laboratory’s system. This includes ensuring the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not included in an electronic chain of custody system.

Screening constitutes an initial rapid check for substances of abuse. While cost-effective for ruling out drug use on most samples, a positive screen must be confirmed for court admissibility. All presumptive positives in Screening require further confirmation.

When a sample tests positive in the Screening phase, additional hair is taken from the initial sample and prepped for Extraction. In this process, substances are isolated from hair at notably lower concentrations compared to other techniques (e.g., urine or oral fluid), making hair drug screening a complex methodology.

Positive results from screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Samples positive in initial screenings are cleansed before final confirmation as necessary. The laboratory process from Accessioning to Confirmation undergoes review both under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

  • Extended detection period: Hair tests can identify drug use up to 90 days, whereas urine tests have shorter detection durations.
  • Resistance to tampering: Hair drug tests are notably difficult to manipulate, enhancing result reliability.
  • Historical data provision: It showcases a pattern of drug consumption over time, rather than just recent use.

Limitations:

  • Recent use detection limitation: Drugs typically become detectable in hair after 5-7 days.
  • Higher cost: Generally, hair drug tests are pricier than alternative drug testing methods.
  • Result variations: Hair color and personal differences in hair growth can impact the level of drug metabolites in hair.

Note: Although commonly termed "hair follicle tests", the analysis targets the hair strand, not the follicle beneath the scalp.

It is frequently used for legal and court requirements, long-term monitoring, and high-trust workforce screening.
Standard hair drug testing typically reflects drug use over approximately a 90-day period, based on the length of hair collected at the time of testing. Longer hair can sometimes reflect a longer time frame, and extremely short hair can reduce that window.
