Hair Follicle Drug Testing - Melby, MN

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of the growing hair strand, hair offers a prolonged history of alcohol and drug presence. When obtained near the scalp, hair can reveal drug and alcohol use for an approximate duration of three months. Hair collection is straightforward, challenging to modify, and simple to transport.

A 1.5-inch portion containing roughly 200 hair strands (similar in size to a #2 pencil) taken nearest to the scalp yields 100mg of hair, which is the optimal sample size for screening and confirmation. For tests like EtG, add-ons, or those exceeding 10 panels, it is advisable to use 150mg of the sample. We suggest using a jeweler’s scale for accurate weight measurement. If scalp hair isn't available, an equal amount from body hair may be used. By head hair, we mean scalp hair exclusively. Body hair encompasses all other types (such as facial, axillary, etc.).

Process Overview

The core steps in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially processed into the lab’s system. This involves ensuring that the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry excluded from an electronic chain of custody system.

The Screening phase entails a preliminary quick assessment for drug abuse. Although Screening is a budget-friendly way to eliminate drug use possibilities in most samples, a positive screen must be validated to stand up in legal proceedings. Any samples flagged as presumptively positive during Screening require subsequent confirmation.

If a sample tests presumptively positive at the Screening phase, additional hair is extracted from the original specimen for the Extraction phase. Here, drug extraction from hair occurs at a considerably lower concentration than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.

The Confirmation of any positive screen result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS technologies. All presumptive positive samples undergo cleansing before confirmation if necessary. The comprehensive lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests that offer a shorter detection timeframe.
• Difficult to manipulate: It is extremely challenging to manipulate a hair drug test, thus enhancing result accuracy.
• Offers historical insight: It can reveal a pattern of drug use across a span of time, not merely recent usage.

Limitations:

• Unable to identify recent use: It generally takes around 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests are usually priced higher than other drug testing methods.
• Result variability: Elements like hair color and individual hair growth differences can influence the concentration of drug metabolites in the hair.

Note: Though commonly termed as "hair follicle tests", the test evaluates the hair strand rather than the follicle beneath the scalp
