Hair Follicle Drug Testing - Winterset, IA

What it is, How it works

Hair testing is recognized as an effective means for detecting drug and alcohol consumption. Hair captures a prolonged history by holding onto biomarkers within the fibers of its growth. When sampled near the scalp, it can reveal drug and alcohol use with a detection window of up to three months. It is simple to collect, tough to tamper with, and convenient to transport.

A sample measuring 1.5 inches long, comprised of about 200 hair strands (roughly the thickness of a #2 pencil) collected nearest to the scalp, provides 100 mg of hair, which is optimal for screening and confirmation. For tests involving EtG, additional panels, or those exceeding 10 panels, 150 mg of the sample is advised. The specimen should ideally be weighed on a jeweler's scale. In the absence of scalp hair, a comparable amount of body hair can be gathered. Head hair specifically indicates scalp hair; body hair includes all other varieties (facial, axillary, etc.).

Process Overview

The laboratory handling of a drug test result involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the preliminary incorporation of a sample into a lab’s system, confirming that the sample is appropriately sealed and dispatched, assigning it a random LAN (Laboratory Accessioning Number), and finalizing any remaining data entry not handled by an electronic chain of custody system.

Screening acts as an initial, quick assessment for drugs of abuse. It offers a cost-efficient method to eliminate drug usage in most specimens, though any positive results need confirmation to be valid in legal proceedings. Presumptive positives found during Screening necessitate a secondary confirmation.

When a sample exhibits a presumptive positive in the Screening phase, additional hair is withdrawn from the original specimen for Extraction preparation. During Extraction, drugs are drawn out from hair in concentrations much lower compared to others (e.g., urine or oral fluid), making hair drug screening a challenging procedure.

Confirming any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples assuming positive results undergo washing before confirmation as required. The entire lab sequence from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the adherence to ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection window: Hair drug tests can reveal drug use over a span of up to 90 days, unlike urine tests which offer a much shorter detection timeframe.
• Hard to fake: Hair drug tests are difficult to trick, resulting in enhanced accuracy.
• Reveals a usage pattern: It can disclose a timeline of drug usage, rather than merely recent activities.

Drawbacks:

• Cannot assess recent usage: It requires approximately 5-7 days before drugs become traceable in hair.
• Expense: Hair drug tests generally incur higher costs compared to other testing methods.
• Result discrepancies: Variations such as hair color and individual hair growth differences can influence the concentration of drug metabolites in hair.

Note: Although often termed "hair follicle tests", the analysis focuses on the hair strand itself rather than the follicle beneath the scalp.
