Accredited Drug Testing offers comprehensive hair follicle drug tests in Stockton, California. When you require a hair drug or alcohol assessment, Accredited Drug Testing is proficient in hair testing, featuring facilities across the nation that conduct these analyses. Typically, 1.5 to 2 inches of hair from your scalp is required, although body hair can also be utilized. These tests evaluate for drugs, alcohol/ETG, and offer customized testing options.

In recent times, the adoption of hair follicle drug tests has surged. Numerous employers, judicial systems, and Substance Abuse specialists now favor hair tests over standard urine tests. This method is preferred by employers enforcing strict no-drug policies, legal systems, and probationary individuals. The hair test's key advantage is its extended drug use detection period, usually lasting up to 90 days. This observation-based collection method is difficult to manipulate. Nonetheless, for drug use detection within the past 5 days, urine tests remain the most precise.

What it is, How it works

Hair testing is recognized as a robust method for identifying drug and alcohol consumption. Hair captures a prolonged history of substance use by embedding biomarkers within the strands as they grow. When harvested near the scalp, hair can offer a detection span of up to roughly 3 months for alcohol and drugs. The collection process is straightforward, difficult to tamper with, and convenient for shipping.

A strand sample measuring 1.5 inches and consisting of around 200 hairs (approximately the thickness of a #2 pencil) cut closest to the scalp yields about 100mg, which is optimal for both screening and confirming. For EtG, additional tests, or panels beyond 10, a specimen size of 150mg is advised. We suggest using a jeweler’s scale to measure the specimen. In the absence of scalp hair, an equivalent volume of body hair is an acceptable alternative. When mentioning head hair, we specifically refer to scalp hair. Body hair encompasses all other types, including facial and axillary hair.

Process Overview

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

Accessioning is the upfront integration of a sample into a lab’s system. This step entails confirming the proper sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and filling in additional data not included in an electronic chain of custody.

Screening is a preliminary and swift evaluation for substance abuse. While it is a cost-efficient measure to exclude drug use in most samples, any positive outcome from Screening must be confirmed for legal admissibility. Samples showing a presumptive positive in Screening mandate further confirmation.

Should a sample show positive in Screening, the initial hair sample is further processed in Extraction. This phase involves extracting drugs from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), rendering hair drug testing the most intricate method to perform.

Positive Screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All potentially positive samples undergo washing before confirmation if required. The entire procedure from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair criteria and in compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection period: Hair tests can reveal drug use for up to 90 days, unlike urine tests with shorter detection spans.
  • Hard to manipulate: Cheating is extremely difficult in hair drug tests, enhancing result accuracy.
  • Displays usage history: It offers insights into drug use trends over time instead of just recent use.

Limitations:

  • Incapable of detecting immediate use: Drugs become detectable in hair roughly 5-7 days post-consumption.
  • Higher cost: Hair drug testing tends to be pricier compared to other testing methods.
  • Result variability: Elements like hair color and individual hair growth variations can influence drug metabolite concentration in hair.

Note: The term "hair follicle tests" is a misnomer as the analysis focuses on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Stockton, CA, the clear advantages of hair follicle tests over urine tests are evident. Detection periods for hair tests are far superior, accurately tracing substances used up to 90 days, unlike urine tests which have shorter detection spans.
