Accredited Drug Testing offers comprehensive hair follicle testing services in Herlong, California. Whether you require a hair drug or alcohol test, our expertise in hair analysis is unmatched, with testing facilities available in cities across the Nation capable of conducting hair tests. Typically, 1.5 to 2 inches of hair from the head or body can be used. Our hair tests detect drugs, alcohol/ETG, and have customizable testing options to suit your needs.

In recent times, the preferred method for drug screening has increasingly been hair follicle testing. Many employers, courts, and experts in Substance Abuse now require hair tests instead of the conventional urine method. It’s favored by companies with strict anti-drug policies, legal systems, and for those on probation. Hair tests have the advantage of a longer detection span, reaching up to 90 days, and are difficult to manipulate due to direct observation during sample collection. However, for detecting recent drug usage, typically within the last 5 days, urine tests remain the most precise option.

What it is, How it works

Hair assessments are now regarded as a significant approach for detecting substance and alcohol consumption. Hair records a lasting history of alcohol and various drugs by capturing biomarkers within the fibers of the new hair strand. When obtained near the scalp, hair can offer up to roughly a 3-month detection period for alcohol and other drugs. Hair is easy to gather, somewhat tough to tamper with, and simple to transport.

A 1.5-inch portion comprising about 200 strands of hair (the size of a #2 pencil) nearest to the scalp will provide 100mg of hair, the ideal sample for analysis and confirmation. For EtG, add-ons, and/or evaluations exceeding 10 panels, 150mg of the sample is recommended. We advise measuring the sample on a jeweler’s scale. If scalp hair is absent, an equivalent amount of body hair can be collected. Referring to head hair indicates only scalp hair. Body hair includes all other hair categories (facial, axillary, etc.).

Process Overview

The four essential stages in the laboratory processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary processing of a specimen into a laboratory’s framework. This includes ensuring proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not supplied by an electronic chain of custody mechanism.

Screening involves an initial rapid check for drugs of abuse. While Screening is an economical way to dismiss drug usage in most samples, a positive screen requires confirmation to be permissible in court. Any specimens that are presumptively positive in Screening need a further confirmation.

Should a specimen be presumptively positive in the Screening phase, additional hair is collected from the initial sample and prepared for Extraction. In this phase, drugs are extracted from hair at a significantly lower concentration than other methodologies (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.

Confirmation of any positive screening outcome is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens are washed before confirmation as necessary. The entire lab procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection timeframe: Hair drug tests can identify drug consumption for up to 90 days, unlike urine tests which have a lesser detection period.
  • Difficulty to tamper: It is extremely challenging to deceive a hair drug test, leading to more accurate results.
  • Supplies historical data: It can present a pattern of drug usage over a stretch of time, not merely recent use.

Limitations:

  • No detection of recent consumption: It requires about 5-7 days for drugs to be detectable in hair.
  • Expense: Hair drug tests typically cost more than other drug testing approaches.
  • Result variations: Elements such as hair color and individual differences in hair growth can influence the drug metabolite concentration in hair.

Note: Although commonly termed as "hair follicle tests", the test itself scrutinizes the hair strand and not the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

The superiority of hair follicle testing over conventional urine tests in Herlong, CA is its unmatched detection accuracy. While urine tests can detect recent drug use, hair testing identifies drug use over longer periods, signifying its reliability. Employers benefit from this enhanced detection ability, as it paints a more comprehensive picture of potential substance use.


Compared to standard urine tests, hair follicle testing is much less prone to interference, increasing the reliability of its results. Employers and legal authorities value this aspect, knowing that hair testing provides a steadfast approach to drug screening without the variables found in urine testing.

Extended Detection Window

Hair follicle testing in Herlong, CA excels in its extended detection window, capable of disclosing drug use up to 90 days prior. This broader time frame gives employers a significant advantage in assessing long-term substance use among candidates or employees. The ability to look back three months provides a wider insight into substance usage behaviors.


Such an extended detection period is beneficial for employers who wish to maintain a stringent drug-free workplace policy. By incorporating hair testing, companies can better understand an applicant’s or employee's history, fostering a safer and more compliant environment.

Tamper-Resistant Testing Method

Unlike urine tests, hair samples are collected in a controlled environment, ensuring that adulteration is virtually impossible. This reliability guarantees the authenticity and integrity of test results.
