What it is, How it works

Hair testing is recognized as a valuable resource for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drugs by embedding biomarkers within its enlarging fibers. Samples taken near the scalp can reveal detection of alcohol and drugs extending up to roughly a 3-month duration. Collecting hair is straightforward, moderately challenging to tamper with, and convenient for transportation.

A 1.5-inch length comprising roughly 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample for analysis and verification. For EtG, supplementary tests, or screenings beyond 10 panels, 150mg of hair is advised. Employing a jeweler’s scale for weighing the sample is suggested. When scalp hair cannot be obtained, an equivalent amount of body hair can be collected. “Head hair” refers solely to scalp hair in this discussion. “Body hair” includes all other types (facial, axillary, etc.).

Process Overview

The drug testing laboratory workflow comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the foundational processing of samples into a lab's system, which incorporates ensuring proper sealing and shipment of samples, generating a random LAN (Laboratory Accessioning Number), and completing any extra data entry not supplied by an electronic chain of custody system.

Screening is an initial expedited assessment for drugs of abuse. Though Screening is an economical approach to dismiss drug usage for most samples, any positive findings necessitate a confirmation step to be legally defensible. Samples with a preliminary positive result in Screening mandate additional confirmation.

If preliminary positivity is indicated during Screening, further hair is prepared from the initial sample for Extraction. Here, drug extraction from hair occurs at a notably lower concentration compared to other methods (e.g., urine or oral fluid), which makes hair drug tests uniquely challenging.

GC/MS, GC/MS/MS, or LC/MS/MS confirm positive screening results. Presumptive positives undergo necessary washing before confirmation. Every step from Accessioning through Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

  • Extended detection period: Hair drug screening can disclose drug consumption for up to 90 days, whereas urine tests offer a briefer detection timeframe.
  • Challenging to manipulate: Compromising a hair drug test is onerous, yielding more reliable outcomes.
  • Tracks historical use: Offers an overview of drug patterns over time, beyond just recent usage.

Limitations:

  • Delayed initial detection: Requires about 5-7 days for drugs to become detectable in hair.
  • Expense: Hair drug testing tends to be pricier than other testing modalities.
  • Result variability: Hair color and individual differences in hair growth can influence drug metabolite concentrations in hair.

Note: Despite being referred to as "hair follicle tests," the evaluation concerns the hair strand itself, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why choose hair over urine testing in Karnack, TX? A hair follicle test vastly outperforms urine tests in accuracy and consistency.
