Accredited Drug Testing offers thorough hair follicle drug testing services in Sierra, California. Whether you require a hair drug or alcohol test, Accredited Drug Testing is your expert, with testing facilities in all major cities across the country that can conduct hair tests. Typically, 1.5 to 2 inches of hair from the head or body can be tested. Hair analysis includes drugs, alcohol/ETG, or other personalized testing options.

Recently, hair follicle drug testing is increasingly favored for drug testing. It is frequently mandated by employers, courts, and Substance Abuse specialists in place of the typical urine test. Employers with strict no-drug-use policies, courts, and those on probation often prefer hair drug tests. The key advantage is a longer detection window for drug usage, generally up to 90 days, with an observed collection to prevent tampering. However, for drug use within the past 5 days, urine tests remain the more precise option.

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol ingestion. Hair captures a prolonged history of alcohol and other substances by encasing biomarkers within the strands as they grow. When gathered near the scalp, hair offers a detection period of up to roughly 3 months for alcohol and other substances. Hair is straightforward to gather, hard to tamper with, and simple to transport.

A 1.5-inch segment of roughly 200 hair strands (equivalent to a #2 pencil width) nearest to the scalp will yield 100mg of hair, which is the optimal quantity for screening and verification. For EtG, add-ons, or tests exceeding 10 panels, 150mg of the sample is advisable. It's suggested to measure the sample using a jeweler's scale. If scalp hair can't be accessed, a comparable quantity of body hair can be collected. "Head hair" refers exclusively to scalp hair; "body hair" pertains to all other hair types (facial, axillary, etc.).

Process Overview

The testing of a drug sample is comprised of four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning concerns the initial handling of a specimen into a laboratory's database. This step involves confirming that the specimen was appropriately sealed and dispatched, allocating a unique LAN (Laboratory Accessioning Number), and filling in any remaining data entry not included within an electronic chain of custody system.

Screening pertains to an initial rapid evaluation for substances. Although Screening is an economical approach to exclude drug use in most instances, a positive result must be verified for court admissibility. Any specimens that appear positive in Screening necessitate subsequent confirmation.

If a specimen is tentatively positive during Screening, additional hair is chosen from the original sample and readied for Extraction. This phase involves extracting drugs from hair at far lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing the most challenging method to execute.

Verification of any positively screened outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive specimens are cleaned before confirmation if necessary. The entire lab process from Accessioning to Confirmation is evaluated following both the CAP (College of American Pathologists) Hair classification and the credentials to ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection window: Hair drug tests can track drug usage for up to 90 days, unlike urine tests which have a briefer detection span.
  • Hard to spoof: It's notably challenging to falsify a hair drug test, ensuring more reliable outcomes.
  • Offers historical insights: It reveals a drug usage pattern over time, rather than just recent consumption.

Limitations:

  • Inability to detect recent consumption: Drugs become detectable in hair approximately 5-7 days after use.
  • Expense: Hair drug tests are typically costlier than other testing techniques.
  • Result discrepancies: Elements like hair color and individual hair growth variations can impact drug metabolite levels in hair.

Note: Often named "hair follicle tests", the test itself examines the hair strand rather than the follicle beneath the scalp.
