Accredited Drug Testing offers comprehensive hair follicle drug assessments in Hercules, California. Whether you need a hair drug or alcohol screening, we specialize in hair testing, with centers across all U.S. cities ready to conduct evaluations. Generally, 1.5 to 2 inches of hair on the head's crown or body are needed. Hair examinations can detect drugs, alcohol/ETG, or be tailored to specific needs.

Recently, hair follicle drug testing has become a favored method. Organizations, legal institutions, and substance abuse experts now often prefer hair analysis over urine tests. This method is favored by employers with strict anti-drug policies, legal courts, and probationers. Hair testing's main advantage is its longer detection period, lasting up to 90 days, involving a monitored collection process, making it nearly tamper-proof. Yet, for recent drug use—within 5 days—urine tests are still the most reliable.

What it is, How it works

Hair testing is recognized as an effective method for detecting drug and alcohol consumption. The hair strands capture biomarkers within the fibers as they grow, providing an extensive history of substance use. By collecting hair near the scalp, it offers approximately a three-month window for tracing alcohol and drug usage. Hair is easy to gather, hard to tamper with, and straightforward to transport.

By cutting a 1.5-inch section of around 200 strands of hair (roughly the girth of a #2 pencil) near the scalp, you obtain 100mg of hair, which is the ideal amount for testing and validation. For EtG, additional analysis, or tests exceeding 10 panels, 150mg is preferred. It is advisable to weigh the sample with a jeweler’s scale. If scalp hair cannot be obtained, a similar mass of body hair can be used. When discussing head hair, it refers solely to scalp hair, while body hair encompasses all other types (such as facial and underarm).

Process Overview

The drug test result processing in a lab comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first phase of inputting a sample into a lab's system. This step ensures the sample is properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and includes any additional data entry not covered by an electronic chain of custody setup.

Screening performs an initial drug abuse inspection. While it effectively identifies drug absence in most samples, confirmed results are needed for legal validity. Samples showing presumed positivity during Screening demand secondary confirmation.

Should a sample result in presumed positivity at the Screening phase, extra hair is taken from the initial specimen for further Extraction. In Extraction, drugs are removed from the hair at a concentration much lower than other methods (e.g., urine or saliva), making hair drug screening the most challenging to execute.

GC/MS, GC/MS/MS, or LC/MS/MS is employed to verify any positive screen results. All presumed positive samples undergo a washing prior to confirmation as necessary. The comprehensive lab process covering Accessioning to Confirmation is assessed per CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

  • Long detection duration: Hair drug tests can trace drug use spanning up to 90 days, contrasting with urine tests which feature a shorter detection timespan.
  • Challenge to outsmart: Hair drug tests present significant difficulty in cheating, ensuring more precise results.
  • Historical insight: It offers an overview of drug use patterns over time, as opposed to merely recent usage.

Limitations:

  • Inability to detect recent usage: Drugs become detectable in hair roughly 5-7 days post-use.
  • Expense: Hair drug tests are typically costlier than other drug testing techniques.
  • Result variations: Aspects like hair color and individual differences in hair growth may influence drug metabolite concentration in hair.

Note: Although often termed "hair follicle tests", the analysis focuses on the hair strand rather than 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.
