In Northeast Marin, California, Accredited Drug Testing offers comprehensive hair follicle drug testing services. Our expertise in hair analysis ensures reliable results for both drug and alcohol testing with centers available in cities nationwide. Typically, 1.5 to 2 inches of hair from the head or body is sufficient for testing. We provide thorough analysis options, including custom testing for various substances.

The preference for hair follicle drug testing has been rising recently. Employers, judicial systems, and substance abuse experts often choose hair tests over traditional urine samples. These tests are crucial for organizations with strict drug-free policies and individuals under court monitoring. The significant advantage is its extended detection period, which spans up to 90 days. However, for detecting recent substance use, urine tests remain preferable within a 5-day window.

What it is, How it works

Hair testing is increasingly regarded as an effective method for detecting drug and alcohol consumption. Hair offers a comprehensive timeline of alcohol and drug usage by embedding biomarkers within the strands of growing hair. When sampled close to the scalp, hair can reveal up to a 3-month detection window for alcohol and other substances. Hair collection is straightforward, challenging to tamper with, and easily transportable.

A 1.5-inch section containing around 200 hair strands (comparable in size to a #2 pencil) nearest the scalp yields 100mg, the optimal sample amount for both screening and confirmation. For EtG, additional parameters, or tests exceeding 10 panels, 150mg of the sample is suggested. We advise measuring the sample with a jeweler’s scale. If head hair is unobtainable, an equivalent quantity of body hair may be used. When mentioning head hair, we refer exclusively to scalp hair. Body hair pertains to all additional hair types (facial, axillary, etc.).

Process Overview

The laboratory analysis of a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial entry of a sample into a lab’s system. This step includes verifying that the sample was correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any other data entry omitted by an electronic chain of custody system.

Screening comprises an initial rapid assessment for drugs of abuse. While Screening offers a cost-efficient means to exclude drug use in the majority of samples, a positive screen must be corroborated for it to be acceptable in legal settings. Any samples showing a presumptive positive result during Screening require subsequent confirmation.

If Screening reveals a presumptive positive outcome, additional hair is extracted from the initial sample and prepared for Extraction. During Extraction, drugs are isolated from hair at significantly lower concentrations than in alternative methods (e.g., urine or oral fluid), making hair drug screening one of the most complex methodologies to conduct.

Confirmation of any positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed prior to confirmation as required. The comprehensive lab procedure from Accessioning to Confirmation undergoes evaluation 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 for up to 90 days, in contrast to urine tests, which have a more limited detection span.
  • Challenging to falsify: Cheating a hair drug test is exceedingly difficult, ensuring more reliable results.
  • Supplies historical insight: It can exhibit a pattern of drug usage over a longer timeframe, not solely recent consumption.

Limitations:

  • Incapable of detecting recent usage: Drugs become detectable in hair after approximately 5-7 days.
  • Price: Hair drug tests are typically pricier than other drug testing techniques.
  • Result variability: Factors like hair color and individual differences in hair growth can influence the levels of drug metabolites within hair.

Note: Although often referred to as "hair follicle tests", the analysis is conducted on the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Northeast Marin, CA, the effectiveness of hair follicle testing far surpasses that of urine tests. Extended detection periods make hair tests ideal for identifying chronic use, providing more comprehensive insights into substance use patterns. Compared to urine tests that detect recent use, hair follicles offer unparalleled accuracy.

While traditional urine tests are limited in detection duration, hair follicle testing covers a longer timeframe, up to 90 days. This superior detection capability makes it the preferred choice for employers with strict substance policies and those seeking reliable results.

Extended Detection Window

Hair follicle testing in Northeast Marin, CA, offers an extended detection window that captures drug use up to 90 days prior. This makes it an invaluable tool for employers seeking a complete picture of an applicant or employee's drug history. The extended timeframe offers more comprehensive data compared to traditional methods.

Employers can gain a detailed view of long-term substance patterns, aiding in making informed hiring or retention decisions. This thorough approach to screening ensures that workplace integrity and safety are maintained.

Tamper-Resistant Testing Method

In Northeast Marin, CA, the design of hair follicle tests significantly reduces the possibility of sample tampering. The tamper-resistant nature of these tests guarantees results that can be trusted to accurately reflect substance use history, diminishing concerns over sample adulteration that are common in other methods.
