Accredited Drug Testing provides comprehensive hair follicle drug testing in Petrolia, California. If a hair drug or alcohol test is required, Accredited Drug Testing excels in hair testing and operates testing centers in every city across the Nation that can conduct a hair test. Typically, 1.5 to 2 inches of hair from the crown of your head or body can be used. Hair tests can be assessed for drugs, alcohol/ETG, or other tailored hair testing needs.

In recent years, the inclusion of hair follicle drug tests in drug testing methods has become more prevalent. Many employers, courts, and Substance Abuse professionals now prefer a hair drug test over the conventional urine test. Hair follicle drug tests are employed by employers with strict drug use policies, courts, and individuals on probation. The main advantage of hair follicle drug testing is its extended detection period for drug use, generally up to 90 days, collected through an observed collection process, making it nearly impossible to tamper with. However, when testing for drug use within the last 5 days, the urine test remains the most precise method.

What it is, How it works

Seen as an effective means for identifying drug and alcohol consumption, hair testing is gaining recognition. Hair can reveal a prolonged history of substance use by capturing biomarkers within the fibers of the growing hair shaft. When collected near the scalp, this method can offer an approximate 3-month detection period for alcohol and drugs. Hair is easy to obtain, relatively tamper-proof, and convenient to transport.

An ideal sample is a 1.5-inch section of roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp, yielding 100mg of hair for both screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is suggested. It is advised to weigh the sample using a jeweler’s scale. If scalp hair is unavailable, a similar amount of body hair can be used. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other types (like facial or axillary).

Process Overview

There are four primary steps in processing a drug test result through the laboratory: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of entering a sample into the lab's system. This process includes confirming the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and inputting any supplementary data not captured by an electronic chain of custody.

Screening involves a preliminary check for substances of abuse. While Screening is a budget-friendly method to rule out most drug use cases, a positive result mandates confirmation to be court-admissible. Samples indicating a presumptive positive in Screening require secondary verification.

Should a sample show presumptive positivity during Screening, additional hair is taken from the original sample for Extraction. In this phase, drugs are extracted from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening notably more challenging to perform.

Confirmation of any positive Screening outcome is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing prior to necessary confirmation. The complete laboratory procedure, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

  • Extended detection period: Hair drug tests can trace drug consumption for up to 90 days, while urine tests offer a shorter detection time.
  • Hard to manipulate: Cheating on a hair test is very challenging, enhancing the reliability of results.
  • Historical insight: It provides a timeline of drug consumption, not merely recent use data.

Limitations:

  • Unable to detect recent consumption: Drugs take about 5-7 days before becoming detectable in hair.
  • Expense: Generally, hair drug tests are costlier than other testing methods.
  • Result variability: Hair color and individual hair growth differences can influence the concentration of drug metabolites in hair.

Note: Commonly known as "hair follicle tests", this testing examines the hair strand and does not analyze 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. Because drug metabolites are incorporated into hair as it grows, this method can show patterns of use instead of just recent exposure. 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.
