Accredited Drug Testing offers comprehensive hair follicle drug screening services in Corcoran, California. Whether you're in need of a hair-based drug or alcohol test, we specialize in this type of assessment and have facilities in cities across the U.S. capable of conducting these tests. Ideally, 1.5 to 2 inches of crown hair or body hair is required. Hair tests can be used for drugs, alcohol/ETG, or other specialized hair analysis.

Over the years, hair follicle drug testing has become an increasingly common approach to drug screening. Many employers, judicial entities, and Substance Abuse professionals prefer hair tests over traditional urine sampling. Hair tests are favored by employers with strict anti-drug policies, courts, and for those on probation. The chief advantage of a hair test is its extended detection period of typically up to 90 days, under a monitored collection, making it nearly foolproof. However, for drug use in the last 5 days, urine remains the best method.

What it is, How it works

Hair analysis has emerged as an effective instrument for identifying usage of drugs and alcohol. Hair offers an extended historical record by capturing biomarkers within the structure of the developing hair strand. When taken from near the scalp, hair can reveal up to roughly a 3-month detection timeframe for alcohol and various substances. Collecting hair is straightforward, relatively hard to tamper with, and simple to transport.

A 1.5-inch segment consisting of around 200 hair strands (resembling the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal amount for analysis and verification. For EtG, additional components, and/or tests exceeding 10 panels, 150mg of the material is advised. Using a jeweler’s scale is suggested for weighing the material. In the absence of scalp hair, a corresponding amount of body hair can be gathered. References to head hair denote only scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The core procedures in laboratory processing of a drug testing outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary introduction of a sample into a laboratory’s framework. It verifies that the sample was properly sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and concludes any further data documentation lacking from an electronic chain of custody system.

Screening serves as an initial rapid assessment for substance abuse. While Screening is economical for eliminating drug presence in most samples, a positive result must be substantiated for legal acceptability. Any samples that appear positive in Screening necessitate further confirmation.

Should a specimen show positivity during the Screening phase, additional hair is extracted from the initial material and readied for Extraction. During this phase, drugs are retrieved from hair at significantly lower concentrations than other techniques (e.g., urine or oral fluid), accounting for the complexity of hair drug testing.

Verification of any positive screening output is performed via GC/MS, GC/MS/MS or LC/MS/MS. All initially positive samples undergo cleansing before verification as needed. The complete laboratory handling from Accessioning to Verification is audited under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

  • Long detection period: Hair drug assessments can trace drug usage for up to 90 days, unlike urine tests which provide a shorter detection period.
  • Challenging to deceive: It is exceedingly hard to manipulate a hair drug test, resulting in more accurate findings.
  • Supplies historical insights: It can demonstrate a pattern of drug use over a timeline, beyond just recent consumption.

Limitations:

  • Cannot identify recent use: It typically takes about 5-7 days for drugs to become traceable in hair.
  • Expense: Hair drug assessments are often costlier than alternative testing techniques.
  • Result variations: Factors such as hair pigmentation and personal differences in hair growth can influence drug metabolite levels in hair.

Note: Although commonly referred to as "hair follicle tests", the examination focuses on the hair strand and not the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle testing to traditional urine tests in Corcoran, CA, the benefits clearly lean towards hair analysis. Hair testing offers unparalleled detection accuracy, providing reliable results over a broad timeframe. While urine tests can be limited, hair testing ensures a more comprehensive understanding of a person's drug use history.

The specialized detection capability of hair tests means that even small amounts of substances are identified with greater accuracy. Whereas urine tests might miss certain drugs or only capture recent usage, hair tests document a robust profile over an extended period, demonstrating reliability unmatched by urine testing.

Extended Detection Window

The extended detection window is a standout feature of hair follicle tests in Corcoran, CA. While other methods offer brief insight, hair analysis spans up to 90 days, allowing employers and authorities a thorough review of substance habits. This long-term view aids in a well-rounded assessment of an individual's drug history.

The ability to detect drug use over such a comprehensive window means that sporadic usage patterns are unlikely to go unnoticed. This feature strengthens employers in making informed decisions regarding new hires or employees under evaluation, building a drug-free workplace with a detailed understanding.

Tamper-Resistant Testing Method
