Accredited Drug Testing offers comprehensive hair follicle drug testing services in Lower Lake, California. Whether you require a hair drug or alcohol test, Accredited Drug Testing specializes in this area, with locations in all cities Nationwide capable of conducting hair tests. Generally, samples require 1.5 to 2 inches of hair from the crown or other body areas for assessment. These tests can screen for drugs, alcohol/ETG, or other tailored hair testing needs.

Recently, drug testing methods increasingly incorporate hair follicle tests. Hair drug tests are preferred by various employers, judicial entities, and Substance Abuse professionals over typical urine tests. These tests benefit employers with zero-tolerance policies, courts, and those on probation due to their extensive detection window for drug use, typically up to 90 days, and because collections occur under supervision, making them nearly foolproof against cheating. Nonetheless, urine tests remain the most accurate for detecting recent drug use within the past five days.

What it is, How it works

The analysis of hair samples has gained recognition as an effective method for identifying drug and alcohol consumption. Hair acts as a chronic record of substances by encapsulating biomarkers within the shaft of the elongating hair. When strands are cut near the scalp, they can reveal drug and alcohol usage for up to a 90-day period. Collecting hair is straightforward, relatively tamper-resistant, and can be easily transported.

A strand sample of 1.5 inches consisting of about 200 hairs (comparable to the thickness of a #2 pencil) near the scalp yields 100mg of hair, which is optimal for both screening and confirming. For testing expansions like EtG or assays over 10 panels, 150mg of the sample is advisable. Measuring the sample with a jeweler’s scale is suggested. If hair from the scalp cannot be collected, an equivalent volume of body hair is acceptable. By "head hair," we specifically mean hair from the scalp, while "body hair" covers all other types (e.g., facial, axillary).

Process Overview

The comprehensive laboratory procedure for processing a drug test result includes Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the primary integration of a specimen into the laboratory framework. This step involves checking that the specimen was properly sealed and delivered, generating a unique LAN (Laboratory Accessioning Number), and completing any supplementary data input not facilitated by an electronic chain of custody system.

Screening provides an initial rapid assessment for the presence of drugs. Though Screening offers an economical way to identify drug consumption in most samples, any positive result must be verified to stand in a legal context. Samples yielding a positive result during Screening require a secondary verification.

For samples indicated as positive during Screening, additional hair is extracted from the initial collection and undergoes the Extraction process. Here, drugs are isolated from the hair at significantly lower concentrations than alternative methods (such as urine or saliva), making it the most challenging testing approach.

Verification of any positive Screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS technology. Every preliminary positive sample undergoes washing ahead of verification if necessary. The whole laboratory operation from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation alongside the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

  • Extended detection timeframe: Hair drug screenings can identify drug use for up to 90 days, unlike urine screenings, which have a narrower detection timeframe.
  • Challenging to falsify: Cheating on a hair drug test is highly challenging, ensuring more reliable results.
  • Offers historical insight: It provides drug use trends over time, not just recent exposure.

Limitations:

  • Inability to identify recent use: Drugs become detectable in hair approximately 5-7 days post-use.
  • Expense: Generally, hair drug screenings are pricier than alternative drug testing techniques.
  • Result variability: Variables including hair color and personal differences in hair growth can impact the levels of drug metabolites in hair.

Note: Although often known as "hair follicle tests," the procedure actually evaluates the hair shaft and not the root below the scalp.
