Accredited Drug Testing provides comprehensive hair follicle drug testing in Fort Washington, California. For those requiring a hair drug or alcohol test, Accredited Drug Testing is proficient in this area, boasting testing locations across all cities nationwide where hair tests can be conducted. Typically, 1.5 to 2 inches of hair on the crown of the head or body is needed, permitting analysis for drugs, alcohol/ETG, or other tailored testing options.

Recently, hair follicle drug testing has been increasingly adopted as a method for substance detection. A growing number of employers, judicial bodies, and Substance Abuse experts mandate hair drug tests over traditional urine tests. Employers enforcing strict drug use rules, courts, and probation officers favor hair follicle tests. Their major advantage includes a significantly extended detection period for drug usage, often up to 90 days, in a supervised manner, making cheating almost impossible. Yet, urine tests remain the most precise for detecting recent drug use within the last 5 days.

What it is, How it works

Hair testing is recognized as a highly effective method for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drug use by retaining biomarkers within the growing strand's fibers. When obtained from near the scalp, hair can offer a detection timeline of up to roughly 90 days for alcohol and drugs. Collecting hair is straightforward, somewhat resistant to tampering, and simple to transport.

A sample measuring 1.5 inches and consisting of approximately 200 hair strands (around the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, ideal for testing and verification. For EtG, additional tests, and screenings beyond 10 panels, it's advised to use 150mg of the sample. We suggest using a jeweler's scale for specimen weighing. If scalp hair is unavailable, an equal volume of body hair is acceptable. References to head hair specifically mean scalp hair. Body hair encompasses all other hair types (facial, underarm, etc.).

Process Overview

The laboratory drug testing process includes four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the sample's initial processing into the lab's system, which involves ensuring the sample was correctly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing data entry not covered by an electronic chain of custody system.

Screening serves as an initial evaluation for drug presence. Although Screening is a cost-efficient manner to dismiss drug use in most samples, positive results in screening must be confirmed for validity in legal scenarios. Samples that yield presumptive positives during Screening need further confirmation.

For samples with presumptive positive Screening results, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are extracted from hair at lower concentrations compared to other techniques (e.g., urine or oral fluids), illustrating why hair drug testing is the most challenging methodology.

Positive Screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation if required. The laboratory workflow from Accessioning to Confirmation undergoes evaluation in adherence to the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

  • Extended detection timeline: Hair drug tests can identify drug usage up to 90 days in contrast to urine tests, which have a shorter detection period.
  • Challenging to manipulate: It is exceedingly tough to deceive a hair drug test, lending greater accuracy to the results.
  • Offers historical insight: It can delineate a pattern of drug use over time, not merely recent usage.

Limitations:

  • Inability to detect recent use: Approximately 5-7 days are necessary before drugs become detectable in hair.
  • Expense: Hair drug tests are typically more costly than alternative drug testing approaches.
  • Variability in outcomes: Elements such as hair color and personal differences in hair growth can influence drug metabolite concentration in hair.

Note: Although commonly termed "hair follicle tests", the test analyzes the hair shaft, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Fort Washington, CA

Hair follicle testing surpasses urine tests by offering an extended detection window for substance use. This makes it more reliable for employers and courts looking to enforce strict drug policies. Unlike urine tests, which detect recent usage, hair tests trace back up to 90 days, providing a broader view of an individual's history.

Additionally, hair testing's superior accuracy minimizes false positives and negatives, ensuring that the results are trustworthy. Employers benefit from this high level of reliability, maintaining compliance with poison-free workplace policies. Thus, hair tests present a more comprehensive and definitive approach to drug detection.

Extended Detection Window

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.
