Hair Follicle Drug Testing - Pleasant Lake, MN

What it is, How it works

Hair testing has emerged as an effective instrument for detecting drug and alcohol consumption. The hair captures a comprehensive timeline of alcohol and drug use by embedding biomarkers within the hair strands as they grow. When collected from the scalp area, hair can reveal a history of up to around 90 days for alcohol and drugs. The hair collection process is straightforward, relatively secure from tampering, and easily transportable.

A hair sample measuring 1.5 inches, consisting of roughly 200 strands (about the diameter of a #2 pencil) nearest to the scalp results in a 100mg sample, the optimal quantity for analysis and verification. For EtG, additional tests, and/or examinations exceeding 10 panels, a specimen size of 150mg is suggested. It’s advisable to use a jeweler’s scale to weigh the specimen. Should scalp hair be unavailable, a comparable amount of body hair is an acceptable substitute. In context, head hair specifically refers to scalp hair, whereas body hair encompasses all other hair categories (e.g., facial, axillary).

Process Overview

The laboratory processing of drug test results involves four critical steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step where the sample is entered into a laboratory’s system. This phase includes checking that the sample's seal and shipment were handled properly, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry needed when not using an electronic chain of custody system.

Screening performs a preliminary scan for substances of abuse. While it is a cost-efficient approach for eliminating drug use suspicions on most samples, a positive screen must be verified to be valid in a legal setting. Samples flagged as presumptively positive during Screening require further confirmation.

During a presumptively positive outcome in Screening, additional hair is extracted from the initial batch and readied for Extraction. In this phase, drugs are extracted from hair at lower concentrations than those in urine or oral fluid tests, contributing to the complexity of hair drug testing.

Confirmation for positive screening outcomes is handled using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Prior to confirmation, all samples with presumptive positives undergo washing as applicable. The full lab process from Accessioning to Confirmation is evaluated in line with both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug usage for up to 90 days, whereas urine tests feature a more limited detection timeframe.
• Difficulty to cheat: Cheating is significantly more challenging with hair drug tests, thereby improving result accuracy.
• Provides historical data: It reveals a timeline of drug consumption, highlighting prolonged use rather than just recent interactions.

Limitations:

• Cannot detect recent use: It requires roughly 5-7 days for drugs to become traceable in hair.
• Cost: Generally, hair drug tests incur higher costs compared to alternative testing methods.
• Variations in results: Variability due to hair color and individual hair growth patterns can alter the amounts of drug metabolites present in hair.

Note: Despite often being termed as "hair follicle tests", the analysis specifically examines the hair strand itself, not the follicle situated underneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Pleasant Lake, MN can be attributed to the superior advantages of hair testing. Compared to traditional urine tests, hair follicle tests offer enhanced detection accuracy and reliability. Hair tests have a longer detection window, making it easier to gain insight into past drug use.
