Accredited Drug Testing provides comprehensive hair follicle drug tests in Herndon, CA. For individuals requiring hair drug or alcohol tests, we offer expertise in hair testing, with facilities available across all cities nationwide to conduct a hair test. Typically, 1.5 to 2 inches of hair from the scalp or other body parts can be used. Hair assessments can detect drugs, alcohol/ETG, and other specific testing preferences.

Recently, drug testing methodologies have increasingly incorporated hair follicle drug assessments. As opposed to conventional urine tests, many employers, judicial systems, and substance abuse experts now prefer hair testing. Employers with zero-tolerance drug policies, courts, and parolees frequently use hair follicle tests. These tests offer prolonged detection times—up to 90 days—are conducted under observation, and are considerably tamper-proof. However, for detecting recent drug intake within a 5-day span, urine tests remain most precise.

What it is, How it works

Hair testing has become recognized as an effective means for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drug use by embedding biomarkers in the fibers of the growing hair. When collected adjacent to the scalp, hair can offer about a 3-month window for detecting alcohol and drugs. Hair is easy to collect, hard to tamper with, and simple to transport.

A 1.5-inch section of approximately 200 hair strands (roughly the width of a #2 pencil) closest to the scalp will yield 100mg of hair, the optimal amount for both screening and confirmation processes. For EtG, additional tests, or those above 10 panels, 150mg of the hair specimen is advised. We recommend using a jeweler's scale to weigh the sample. If scalp hair is not available, a comparable quantity of body hair may be used. "Head hair" refers exclusively to scalp hair. "Body hair" includes all other types (facial, axillary, etc.).

Process Overview

The laboratory process for analyzing a drug test result involves four significant steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial processing step where a sample is integrated into a laboratory's system. This step includes verifying the sample's sealed and proper shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data not contained within an electronic chain of custody system.

Screening involves an initial rapid test for drugs of abuse. Although Screening is a cost-effective way to rule out drug use in most samples, a positive result must be confirmed to be court-admissible. Any samples indicating presumptive positive results in Screening must have secondary confirmation.

Should a sample test presumptively positive during the Screening phase, more hair is gathered from the initial sample and prepared for Extraction. In this stage, drugs are extracted from hair at a much lower concentration than in other methods (e.g., urine or oral fluid), which is why hair drug testing is the most challenging method to perform.

Confirmation of any positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positives are cleaned prior to confirmation as required. The entire laboratory process from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and is accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extensive detection window: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests, which have a less extended detection window.
  • Difficulty to manipulate: It is tough to manipulate a hair drug test, enhancing the accuracy of the results.
  • Indicates historical data: It can demonstrate a pattern of drug use over time, not just recent consumption.

Limitations:

  • Cannot detect recent consumption: Drugs take approximately 5-7 days to become detectable in hair.
  • Expense: Hair drug tests are typically more costly compared to other drug testing methods.
  • Result variations: Aspects such as hair color and individual hair growth differences can influence the concentration of drug metabolites in hair.

Note: While commonly called "hair follicle tests," the test itself evaluates the hair strand, not the follicle under the scalp.
