In Calwa, California, Accredited Drug Testing provides comprehensive hair follicle drug testing services. Whether you are in need of a hair drug or alcohol test, our expertise in hair testing ensures that we have facilities across all cities nationwide ready to carry out the procedure. Generally, 1.5 to 2 inches of hair from the scalp or body is needed. Hair tests are versatile, detecting drugs, alcohol/ETG, or offering various tailor-made options.

Over recent years, hair follicle tests have increasingly become a go-to method for drug testing. Many employers, legal entities, and substance abuse counselors prefer hair drug tests over the conventional urine tests. Hair follicle drug tests serve those with zero-tolerance drug policies, the judicial system, and individuals under probation. The major advantage lies in its prolonged detection period, extending up to 90 days, and offering an observed collection process that is hard to compromise. For drug use within the last five days, however, urine tests still provide the highest accuracy.

What it is, How it works

Hair examinations have emerged as a robust method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug biomarkers within the fibers of a growing strand. When taken near the scalp, hair offers up to approximately a 3-month detection period for substances. Hair collection is straightforward, resistant to tampering, and convenient for shipping.

A close-to-scalp 1.5-inch lock comprising around 200 hair strands (roughly the girth of a #2 pencil) provides 100mg of hair, ideal for testing and verification. For EtG, addon tests, and/or panels exceeding 10, 150mg is advised. We suggest measuring the sample using a jeweler’s scale. If scalp hair is absent, a similar quantity of body hair can be utilized. When mentioning head hair, we specifically mean scalp hair only. 'Body hair' refers to all other types (e.g., facial, axillary, etc.).

Process Overview

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

Accessioning denotes the sample's initial integration into a lab system, ensuring the sample was properly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any further data input lacking from an electronic chain of custody.

Screening provides an initial rapid assessment for substance abuse. Although Screening economically excludes drug presence for most specimens, a positive result necessitates confirmation to be court-admissible. All presumptively positive samples from Screening need subsequent confirmation.

Should a sample be presumptively positive in Screening, additional hair is extracted from the first sample and readied for Extraction. Here, drugs are extracted from hair at significantly reduced concentrations than other methods (e.g., urine or oral fluids), making hair drug testing the most challenging method to execute.

GC/MS, GC/MS/MS, or LC/MS/MS are used for confirming any positive screening findings. All positive samples are appropriately washed before Confirmation. The entire lab process from Accessioning through to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection window: Hair drug screenings reveal drug intake for up to 90 days, unlike urine tests with shorter timelines.
  • Difficult to manipulate: Cheating on a hair drug test is challenging, leading to more reliable results.
  • Historical data provision: Offers patterns of drug consumption over time, rather than just recent usage.

Limitations:

  • Incapability to identify recent consumption: Drugs take about 5-7 days to become detectable in hair.
  • Expense: Hair drug tests typically cost more than other testing techniques.
  • Result variations: Elements like hair color and personal hair growth differences can influence drug metabolite levels in hair.

Note: Although called "hair follicle tests," the analysis targets 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.
