Accredited Drug Testing offers comprehensive hair follicle drug testing services in Kelseyville, California. If you're looking for a hair drug or alcohol test, Accredited Drug Testing specializes in such assessments, and we have centers across various cities nationwide equipped to perform these tests. Generally, 1.5 to 2 inches of hair from the head or body is required. Hair tests can identify drugs, alcohol/ETG, or other customized options.

Recently, the method of drug testing has increasingly incorporated hair follicle tests. Numerous employers, judicial bodies, and Substance Abuse professionals are now opting for hair drug tests over the traditional urine tests. Hair follicle drug tests are preferred by employers with zero-tolerance drug policies, courts, and those supervising probationers. The main advantage is that these tests have a much longer detection span—up to 90 days—are performed under observation, and are nearly tamper-proof. Nevertheless, for detecting recent drug use within 5 days, urine tests remain most precise.

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair offers an extended timeline of alcohol and other drug use by embedding biomarkers within the fibers of the developing hair strand. When taken near the scalp, hair can reveal up to a roughly three-month detection period for alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and easy to transport.

A 1.5-inch segment of approximately 200 hair strands (around the width of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample for testing and verification. For EtG, add-ons, or analyses beyond 10 panels, a 150mg sample is advisable. We suggest using a jeweler’s scale to weigh the specimen. If scalp hair is lacking, an equivalent quantity of body hair may be used. When mentioning head hair, we refer specifically to scalp hair. Body hair denotes all other types (e.g., facial, axillary).

Process Overview

The lab processing of drug test results includes four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is about the initial integration of a sample into a lab’s database. It covers checking that the sample was correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and filling in any missing data not supplied by a digital chain of custody system.

Screening involves a preliminary rapid test for drugs of abuse. Although Screening is a cost-effective way to eliminate drug usage in most samples, a positive screen must be verified for court acceptability. Any presumptively positive samples in Screening necessitate further confirmation.

Samples deemed presumptively positive during Screening require more hair from the initial sample for Extraction preparation. This step involves extracting drugs from hair at a considerably lower concentration than alternative methods (e.g., urine or oral fluid), illustrating the complexity of hair drug screening.

Confirmation of any positive Screening result is done via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The complete lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection period: Hair drug tests detect drug usage for up to 90 days, unlike urine tests which have a shorter detection period.
  • Hard to falsify: Cheating a hair drug test is very challenging, leading to more accurate results.
  • Offers historical insights: Provides a trend of drug use over time, not merely recent use.

Limitations:

  • Cannot identify recent use: Drugs become noticeable in hair approximately 5-7 days post-use.
  • Expense: Hair drug tests generally cost more than other drug testing techniques.
  • Result variability: Factors like hair color and individual differences in hair growth can influence drug metabolite levels in hair.

Note: Often referred to as “hair follicle tests", the analysis actually examines the hair strand, not the follicle beneath the scalp.

Frequently Asked Questions

A hair follicle drug test analyzes a small sample of hair to detect a history of drug use over time.

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.
Hair drug testing commonly screens for marijuana/THC, cocaine, opiates/opioids, amphetamines/methamphetamines, and PCP. In many cases, additional expanded panels may be requested to include other substances.
Yes. If the donor's head hair is too short or unavailable, body hair may be collected as an alternative. The collector will document the source of the sample. This allows testing even for individuals with recently cut or shaved head hair.
Yes. Hair drug testing is commonly used in court, probation, custody, and compliance matters because the collection process follows a documented chain of custody and the analysis is performed by a certified laboratory.
