Hair Follicle Drug Testing - Holy Cross, IA

What it is, How it works

Hair analysis has become recognized as a potent method for uncovering the consumption of drugs and alcohol. Hair serves as a timeline for alcohol and drug usage by embedding markers within the strands as they grow. When sampled near the scalp, hair can reveal substance use within a roughly 3-month timeframe. Collecting hair is straightforward, challenging to tamper with, and convenient to send.

A 1.5-inch collection of around 200 hair strands (comparable to a #2 pencil in size) near the scalp yields 100mg, the optimal amount for both initial testing and validation. For EtG, add-ons, or tests beyond 10 panels, a 150mg sample is suggested. We advise using a jeweler’s scale to weigh the specimen. If scalp hair is absent, a similar quantity of body hair can be used. When mentioning head hair, it specifically means scalp hair. Body hair encompasses all other types (e.g., facial, axillary).

Process Overview

The laboratory procedure for drug test results includes four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning handles the sample’s initial entry into the lab’s system. This step involves ensuring the sample was sealed and transported accurately, generating a random LAN (Laboratory Accessioning Number), and completing any extra data input not covered by an electronic chain of custody system.

Screening consists of an initial evaluation for potential drug misuse. Although Screening helps efficiently dismiss drug use in most cases, positive results require confirmation to be valid in legal settings. Any samples with presumptive positives must undergo additional confirmation.

In cases where Screening suggests a positive result, additional hair is taken from the original batch and prepped for Extraction. Here, drug extraction from hair occurs at substantially lower concentrations than with other methods (e.g., urine or oral fluid), making hair drug analysis one of the more complex techniques.

Validation of any positive screen result is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positivity are cleaned before confirmation. The comprehensive lab process from Accessioning to Confirmation follows CAP (College of American Pathologists) Hair standards and accreditation to ISO / IEC 17025 norms.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can reveal drug usage for up to 90 days, unlike urine tests which have a shorter timeframe.
• Hard to manipulate: Hair drug tests are challenging to alter, leading to more precise outcomes.
• Tracks usage history: These tests can show a pattern of drug use over time, not solely recent activity.

Limitations:

• Incapable of detecting recent usage: Drugs become noticeable in hair approximately 5-7 days post-consumption.
• Higher cost: Hair drug tests typically incur higher expenses than other testing avenues.
• Result variability: Differences such as hair color and individual hair growth rate can influence drug metabolite concentration in the hair.

Note: Although often termed "hair follicle tests," the examination itself targets the hair strand and not the hair follicle beneath the scalp
