Hair Follicle Drug Testing - Forest Knolls, CA

What it is, How it works

Hair analysis has become recognized as an effective method for identifying drug and alcohol consumption. Hair captures a comprehensive timeline of drug and alcohol usage by embedding biomarkers within the strands of hair as it grows. When gathered near the scalp’s surface, hair offers up to an approximate 3-month timeframe for detecting alcohol and drugs. Hair is easy to gather, challenging to tamper with, and straightforward to send.

A sample measuring 1.5 inches with approximately 200 hair strands (roughly the size of a #2 pencil) closest to the scalp yields 100mg of hair, the perfect amount for both screening and confirmation. For testing that includes EtG, add-ons, and/or panels exceeding 10, 150mg is advised. We suggest using a jeweler's scale to measure the sample. If scalp hair is not accessible, an equivalent amount of body hair can be used. When mentioning head hair, we refer solely to scalp hair. Body hair encompasses all other hair categories (e.g., facial, axillary).

Process Overview

The laboratory processing of a drug test result encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial phase of entering a sample into a laboratory’s system. This involves assuring the sample was properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any data entry not supplied by an electronic chain of custody system.

Screening consists of an initial rapid check for substances of abuse. While Screening is a cost-efficient method to exclude drug use in most samples, any positive screening result must be confirmed for it to be valid in legal proceedings. Samples that test presumptively positive in Screening require further confirmation.

If Screening indicates a presumptively positive result, additional hair is extracted from the original sample for the Extraction process. In this method, drugs are extracted from hair at significantly lower concentrations than with other methods (e.g., urine or oral fluids), highlighting why hair drug screening is notably challenging to execute.

Verification of any positive screening outcome is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive undergo washing before confirmation as necessary. The full laboratory procedure, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to 90 days, unlike urine tests which have a more limited detection period.
• Challenging to manipulate: It is very challenging to subvert a hair drug test, enhancing the accuracy of results.
• Offers pattern history: It provides insight into patterns of drug use over a span of time, as opposed to just recent usage.

Limitations:

• Inability to detect recent use: It takes about 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests generally incur higher costs than other testing methods.
• Result variability: Factors such as hair color and individual differences in hair growth can impact the level of drug metabolites found in the hair.

Note: Despite being commonly termed as "hair follicle tests", the test evaluates the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why choose hair follicle testing over urine tests in Forest Knolls, CA? Hair tests exhibit remarkable advantages compared to traditional urine tests through superior accuracy and a more reliable detection window. Unlike urine tests, which may only capture recent substance use, hair testing unveils a wider timeline of consumption, offering more insightful data for assessing patterns of drug use effectively.

With its capacity for better detection accuracy, hair testing enhances trustworthiness in outcomes delivered. This minimizes risks of false negatives which are more common with urine-based testing methods. Consequently, hair follicle testing represents a more precise, comprehensive approach for understanding long-term patterns of substance use.

Extended Detection Window

In Forest Knolls, CA, hair follicle tests expose drug use over an extended 90-day window, offering a thorough look into an individual’s substance history. Unlike short-term tests, hair testing reveals patterns over longer periods, supporting employers in making informed choices regarding workforce composition and management, decreasing the chances of oversight on drug usage.

The broad detection scope provides valuable insights into past substance use, aiding in evaluation processes for both current and potential employees. In doing so, employers gain pivotal data reflecting an individual’s history of drug consumption, equipping them to better navigate employment decisions regarding drug policies.

Tamper-Resistant Testing Method

Hair follicle testing in Forest Knolls, CA enhances integrity by significantly reducing the potential for tampering. This test method offers an almost unmodifiable capture medium that ensures the samples remain unaffected by outside alteration, unlike urine tests which can be undermined by adulterative or substitution tactics, intentionally external influences are minimized for accurate results.

The robust nature of hair tests assures trustworthy findings, making them indispensable to ensure authenticity and correctness. Moreover, the likelihood of deceptive practices reduces ensuring companies and stakeholders benefit from dependable, direct insights into substance use patterns without compromising on veracity.
