Accredited Drug Testing offers thorough hair follicle drug testing services in Knightsen, California. Whether you require a drug or alcohol hair test, our expertise lies in hair testing, with centers accessible in all cities nationwide. Typically, 1.5 to 2 inches of hair from the head or body suffices. These tests can assess the presence of drugs, alcohol/ETG, or other specified substances.

Lately, hair follicle drug tests are increasingly utilized for drug testing. Many employers, judicial systems, and substance abuse experts favor hair drug tests over the conventional urine tests. Such tests are crucial for employers enforcing strict no-drug policies, legal courts, and individuals under probation. A notable advantage of hair tests is their extended detection duration, typically up to 90 days, and the difficulty in falsifying results. Yet, urine tests remain the go-to for recent drug intake, specifically within a five-day span.

What it is, How it works

As a proficient means for identifying drug and alcohol intake, hair testing is gaining recognition. Hair can capture prolonged records of alcohol and other drugs by ensnaring biomarkers within its growing strands. A segment taken near the scalp can present an approximately 3-month detection span for substances. Hair is straightforward to collect, challenging to tamper with, and easy to dispatch.

A 1.5-inch segment comprising roughly 200 hair strands (comparable to a #2 pencil’s breadth) adjacent to the scalp yields 100mg, which is optimal for initial analysis and confirmation. For EtG, supplementary, and/or examinations exceeding 10 panels, 150mg of the sample is advisable. We suggest verifying the specimen’s weight using a jeweler’s scale. In the absence of scalp hair, an equal volume of body hair may be harvested. By head hair, we imply specifically scalp hair. Body hair denotes alternative hair forms (facial, axillary, etc.).

Process Overview

The key procedures in laboratory drug test processing comprise Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the sample’s initial integration into a laboratory’s framework. This process confirms proper sealing and shipment, allocates a random LAN (Laboratory Accessioning Number), and completes any missing data entry unsupplied by an electronic custody chain system.

Screening consists of a preliminary examination for substances of abuse. Although Screening is an economical means to negate drug consumption in most samples, a positive screen necessitates confirmation for court validity. Samples that show presumptive positivity in Screening must undergo follow-up confirmation.

If a sample is deemed presumptively positive at the Screening juncture, additional hair is extracted from the original sample and readied for Extraction. Here, drugs are extracted at considerably lower concentrations than in alternative methods (for example, urine or oral fluid), making hair drug screening the most complex procedure.

Confirmation for any positive Screening outcome occurs via GC/MS, GC/MS/MS or LC/MS/MS. Necessary presumptive positive samples undergo washing prior to confirmation. The complete laboratory process from Accessioning through Confirmation adheres to both the CAP (College of American Pathologists) Hair standard and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

  • Extended detection interval: Hair drug assessments reveal drug intake for up to 90 days, unlike urine screenings which offer a briefer detection period.
  • Hard to deceive: Given hair drug testing’s complexity, result accuracy is enhanced.
  • Reveals historical usage: It charts a drug use pattern over an extended timeframe, beyond just recent consumption.

Limitations:

  • Cannot identify recent intake: Drugs become traceable in hair around 5-7 days after use.
  • Expense: Hair drug tests are typically pricier compared to alternative testing approaches.
  • Result variability: Elements such as hair color and differing individual hair growth rates may influence drug metabolite concentrations in hair.

Note: Although frequently termed "hair follicle tests", the examination targets the hair strand rather than the scalp’s hair follicle.

Why Hair Follicle Testing Beats Urine Testing

In Knightsen, CA, hair follicle testing stands superior compared to traditional urine tests. The hair method boasts enhanced detection accuracy and reliability, significantly minimizing errors. While urine tests can be affected by temporary lapses in drug use, hair tests offer continuity in monitoring, giving a clearer picture of substance intake over time.

Traditional urine tests have limitations in detection timeframes, often missing longer-term drug use. In Knightsen, employers and legal authorities increasingly turn to hair follicle testing for its capacity to detect substances over extended periods, providing peace of mind with its robust results.

Extended Detection Window

One outstanding feature of hair follicle testing in Knightsen, CA, is its extensive detection window, covering up to 90 days. This offers a panoramic view of an individual's substance history, which is invaluable for employers looking to evaluate potential hires thoroughly.

The range of detection proves beneficial for workplace compliance, as employers ascertain long-term substance use patterns. In Knightsen, CA, the ability to look beyond mere days supports a culture of strict adherence to drug-free policies, maintaining high standards of workplace integrity.

Tamper-Resistant Testing Method

In Knightsen, CA, hair follicle testing offers a significant defense against sample tampering, ensuring the results' integrity. The nature of hair samples makes them hard to adulterate compared to other testing methods, providing a foolproof solution for detecting drug use. This reliability is crucial in sensitive circumstances where accuracy cannot be compromised.

The robustness of hair follicle tests means that results cannot be easily manipulated, offering peace of mind to employers and officials in Knightsen. Trust in the results is non-negotiable, and hair testing provides assurance against falsification and dishonesty.
