Accredited Drug Testing offers comprehensive hair follicle drug testing services in Hillsborough, California. When in need of a drug or alcohol hair test, Accredited Drug Testing excels in hair analysis, with centers nationwide ready to conduct the test. Typically, 1.5 to 2 inches of hair is needed from the scalp, or body hair can be used as an alternative. Tests can analyze for drugs, alcohol/ETG, or be customized for other hair testing requirements.

Recently, drug testing procedures have increasingly incorporated hair follicle tests. Employers, courts, and substance abuse professionals often opt for this method over traditional urine tests. Hair follicle tests are favored by employers with strict drug use policies, judicial systems, and probation officers. They offer a longer detection window for drug usage, typically up to 90 days, with observed collection making them almost foolproof. However, urine tests remain the most reliable for detecting drug use within a recent 5-day window.

What it is, How it works

Hair analysis has emerged as a significant method for identifying drug and alcohol consumption. Hair strands capture biomarkers within their fibers, offering a comprehensive timeline of alcohol and drug exposure. When hair is sampled near the scalp, it can reveal usage for a period of up to three months for alcohol and other substances. Hair sampling is straightforward, tamper-resistant, and simple to transport.

Collecting a 1.5-inch portion made up of nearly 200 hairs (akin to the size of a #2 pencil) from the scalp yields 100mg, an optimal amount for both screening and verification. For tests such as EtG, add-ons, and assays exceeding 10 panels, a specimen of 150mg is suggested. We advise using a jeweler’s scale to measure the sample. In cases where scalp hair is missing, an equivalent quantity of body hair may be utilized. Reference to head hair specifically implies scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Outline of Procedures

The four crucial phases in lab processing of a drug test include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase where the sample is logged into the lab's system. This stage ensures the sample was sealed and dispatched correctly, assigns an arbitrary LAN (Laboratory Accessioning Number), and finishes any pending data input absent in an electronic custody trail.

Screening involves a preliminary evaluation for substances of abuse. While Screening is an economical method to eliminate drug usage in most cases, a positive finding necessitates further confirmation for legal acceptance. Any samples that test positive during Screening require additional confirmation.

If a sample tests positive during the Screening phase, more hair is extracted from the original sample and readied for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations compared to other techniques like urine or oral fluids, making hair drug testing a more complex process.

Confirmation for any positive screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with a presumptive positive result are cleansed before confirmation as needed. The entire lab processing cycle from Accessioning through Confirmation is evaluated under both the CAP (College of American Pathologists) Hair classification and the accreditation standards of ISO / IEC 17025.

Benefits of hair drug testing:

  • Extended detection timeframe: Hair drug analyses can reveal drug consumption for as long as 90 days, compared to urine tests which detect recent usage over shorter periods.
  • Challenging to falsify: Cheating a hair drug test is notably difficult, enhancing result reliability.
  • Offers longitudinal data: It displays a record of drug consumption over time, beyond just recent usage.

Drawbacks:

  • Inability to detect recent ingestion: Drugs typically become traceable in hair after roughly 5-7 days.
  • Expense: Generally, hair drug analyses incur higher costs than other test types.
  • Result variability: Variables such as hair color and growth rates can alter the drug metabolite concentrations within hair.

Note: Typically, these are termed "hair follicle tests", although the analysis targets the hair strand itself, not the follicle embedded in the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Hillsborough, CA, hair follicle testing is increasingly surpassing traditional urine tests in popularity. One reason is its superior detection capability. Since substances remain in hair longer, detecting drug use is more comprehensive. In workplaces, this means a clearer overview of employees' drug habits, unlike urine tests that have a much shorter detection period.

Extended Detection Window

Hair follicle testing offers an extended detection window, making it highly effective in Hillsborough, CA. This method can uncover drug usage for up to 90 days prior, offering employers a thorough understanding of an employee or candidate's history. Such a wide detection range ensures that informed decisions can be made based on detailed substance use data.

Tamper-Resistant Testing Method

The tamper-resistant nature of hair follicle tests ensures reliable outcomes, crucial for Hillsborough, CA. Hair tests significantly lower the risk of sample alteration, with results being nearly impossible to fake. This testing method reassures employers and legal bodies of the authenticity of the findings, making it a preferred choice for many institutions.
