Hair Follicle Drug Testing - Holt, MN

What it is, How it works

Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. This method captures long-term indicators of alcohol and drugs within the fibers of the hair as it grows. When collected close to the scalp, hair offers up to about a three-month window for detecting alcohol and drug use. Hair collection is straightforward, relatively tamper-proof, and easy to transport.

A 1.5-inch sample, approximately 200 strands (around the size of a #2 pencil), nearest to the scalp yields 100mg of hair, which is optimal for both screening and confirming tests. For EtG, add-ons, or panels exceeding 10 tests, 150mg of hair is advisable. Utilizing a jeweler's scale to weigh the sample is recommended. If scalp hair is unavailable, a comparable quantity of body hair can be used. The term 'head hair' refers specifically to scalp hair, whereas 'body hair' encompasses all other types (such as facial or axillary hair).

Process Overview

The laboratory processing of a drug test result is structured into four crucial phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of bringing a sample into the lab's system. This phase involves checking that the sample was properly sealed and shipped, assigning a Laboratory Accessioning Number (LAN), and completing any additional data recording needed if an electronic chain of custody system is not utilized.

Screening involves an initial rapid assessment for drugs of abuse. Although Screening is a cost-efficient way to exclude drug usage for most samples, positive results must be confirmed for legal proceedings. Any samples that yield presumptive positives must undergo further confirmation testing.

When a sample shows a presumptive positive during Screening, additional hair is taken from the original sample for the Extraction phase. Drugs are extracted at lower concentrations from hair than from other sources (such as urine or oral fluids), thus making hair drug screening particularly challenging.

Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positives are washed before Confirmation if necessary. The entire lab process, from Accessioning to Confirmation, is scrutinized under CAP (College of American Pathologists) Hair criteria and follows ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair tests can reveal drug use for up to 90 days, unlike urine tests, which offer a shorter detection window.
• Challenging to manipulate: Hair drug tests are hard to tamper with, which enhances the reliability of the results.
• Tracks usage patterns: Provides insight into the timeline of drug use over a prolonged period, rather than just recent consumption.

Limitations:

• Inability to detect new usage: Drugs become detectable in hair roughly 5-7 days post-consumption.
• Expense: Hair drug testing is typically more costly compared to other methods.
• Result variability: Elements like hair color and individual hair growth variances can influence drug metabolite concentrations in hair.

Note: While often referred to as "hair follicle tests", the analysis is conducted on the strand of hair, not the follicle beneath the scalp.
