Accredited Drug Testing provides comprehensive hair follicle drug testing services in Downey, California. If you seek a hair drug or alcohol test, we excel in hair testing, with centers nationwide ready for testing. Generally, 1.5 to 2 inches of hair from your head or body can be used. Hair samples can be examined for drugs, alcohol/ETG, or tailored testing choices.

Recently, drug testing has more commonly included hair follicle tests. Many employers, courts, and substance abuse experts mandate hair tests over standard urine tests. Hair drug tests are employed by organizations with strict anti-drug policies, including courts and those on probation. The primary advantage of hair tests is their extended detection period, typically up to 90 days, with observation during collection, making it nearly cheat-proof. Yet, for detecting drug use within the last 5 days, urine tests remain the most accurate.

What it is, How it works

Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. It offers an extended timeline of substance use by capturing biomarkers within the strands of the growing hair. When taken near the scalp, hair samples can reveal drug and alcohol usage within approximately a 90-day timeframe. Hair is easy to gather, challenging to alter, and simple to transport.

A sample of 1.5 inches, consisting of around 200 hair strands (roughly equal to a #2 pencil), should yield 100mg—perfect for screening and confirmation purposes. For EtG, supplemental checks, and/or panels exceeding 10, a 150mg sample is advisable. It's suggested to measure the sample using a jeweler’s scale. If scalp hair is absent, an equivalent amount of body hair may be used. In our context, head hair implies scalp hair exclusively. On the other hand, body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory procedure for processing a drug test result comprises four essential steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails integrating a sample into a lab’s system initially. It includes verifying the proper sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any outstanding data input absent in an electronic chain of custody setup.

Screening executes an initial swift assessment for substance misuse. Although Screening is a budget-friendly method for negating drug use in most samples, a positive screening outcome must be substantively confirmed to hold up in legal contexts. Samples screened as presumptively positive necessitate additional confirmation.

If a sample yields a presumptively positive result during Screening, more hair is extracted from the original sample and readied for Extraction. During this phase, substances are derived from hair at significantly lower concentrations than in other techniques (e.g., urine or oral fluid), rendering hair drug screening the most intricate methodology available.

Positive results identified during Screening undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples presumed positive warrant a wash prior to confirmation, where necessary. The entire lab process, spanning from Accessioning to Confirmation, undergoes scrutiny adhering to both the CAP (College of American Pathologists) Hair designation and alignment with ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

  • Extended detection period: Hair drug tests can identify drug consumption up to 90 days, surpassing the shorter detection times of urine tests.
  • Complexity of deception: It is nearly impossible to manipulate a hair drug test, enhancing the credibility of the outcomes.
  • Chronological data provision: Tests depict a usage pattern over a prolonged timeframe, rather than just recent usage.

Limitations:

  • Inability to detect immediate use: It requires roughly 5-7 days for substances to become traceable in hair.
  • Expense: Hair drug testing tends to be pricier compared to other drug testing methodologies.
  • Variability in findings: Factors such as hair pigmentation and individual differences in hair growth can influence metabolite concentrations in hair.

Note: Although commonly termed "hair follicle tests", the procedure examines the hair strand, not the follicle from beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

Extended Detection Window

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.
