Accredited Drug Testing offers comprehensive hair follicle drug screening services in Crannell, California. Whether you require hair drug or alcohol testing, Accredited Drug Testing specializes in hair examinations, with facilities in all cities nationwide prepared to conduct tests. Generally, 1.5 to 2 inches of hair from your crown or body may be used. Hair tests can discern drugs, alcohol/ETG, or other custom testing solutions.

In recent years, hair follicle testing has gained traction over other methods. Increasingly, employers, courts, and Substance Abuse professionals are opting for it instead of the routine urine tests. Employers with zero-tolerance policies, court systems, and those on probation find hair follicle tests invaluable. The standout advantage is the extended drug detection window of up to 90 days, ensured by direct collection, making tampering nearly impossible. Nonetheless, urine tests excel in detecting drug use in the past 5 days.

What it is, How it works

The use of hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair stores a prolonged record of alcohol and drug use by embedding biomarkers in the growing hair fibers. When gathered near the scalp, hair can offer a detection span of up to around 3 months for drugs and alcohol. Its collection is straightforward, relatively resistant to tampering, and easy to transport.

A 1.5-inch segment comprising roughly 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, ideal for both screening and confirmation. For EtG, additional tests, and/or panels beyond 10, a specimen weighing 150mg is suggested. It's advisable to weigh the specimen using a jeweler's scale. If scalp hair cannot be obtained, an equal volume of body hair might be used. When mentioning head hair, we refer solely to scalp hair. Body hair denotes all other forms (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test outcome encompasses four main stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initial integration of a sample into a lab's system. This stage ensures the sample is correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and finishes any extra data entry missing from an electronic chain of custody system.

Screening provides an initial swift detection of drugs. While efficient for excluding drug use in most samples, a positive screening must be confirmed for court acceptance. Any samples deemed positive in Screening require further validation.

Samples showing positive results in the Screening stage undergo more hair extraction from the original specimen for the Extraction stage. Here, drugs are extracted from hair at significantly lower concentrations than other techniques (e.g., urine or oral fluid), hence why hair drug screening is considered the most challenging technique.

Confirmation of any positive screening result employs GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples with presumptive positives are cleansed before confirmation as necessary. The entire lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

  • Extended detection span: Hair drug tests identify drug use for up to 90 days, unlike urine tests which offer a shorter detection span.
  • Hard to manipulate: Manipulating results of a hair drug test is quite challenging, thus enhancing accuracy.
  • Historical data supply: This test highlights a timeline of drug use over time, not merely recent activity.

Limitations:

  • Inability to detect recent use: Detectability of drugs in hair requires about 5-7 days.
  • Expense: Hair drug tests typically cost more than alternative drug testing approaches.
  • Result variations: Differences such as hair color and individual hair growth variations can impact drug metabolite concentrations in hair.

Note: Despite commonly being labeled as "hair follicle tests", the examination focuses on the hair strand rather than the follicle below the scalp.
