Hair Follicle Drug Testing - Postville, WI

What it is, How it works

Hair examination has emerged as an effective means for identifying the use of drugs and alcohol. Hair strands trap and hold biomarkers, providing a prolonged history of substance use within their fibers. When slicing hair near the scalp, it captures an estimated 3-month detection timeline for alcohol and drugs. Hair's collection is straightforward, it's relatively tough to tamper with, and it's easy to transport.

A hair sample of 1.5 inches comprising roughly 200 strands (similar to a #2 pencil's width) nearest to the scalp will yield 100mg, which is the ideal quantity for both screening and confirmation. For EtG, add-ons, or for analyses exceeding 10 panels, a sample size of 150mg is advisable. We suggest using a jeweler's scale for weighing. If scalp hair can't be sourced, an equivalent mass of body hair can be used. References to head hair imply only scalp hair, whereas body hair encompasses hair from other areas (facial, axillary, etc.).

Process Overview

The primary four phases in the laboratory's drug test analysis are Accessioning, Screening, Extraction, and Confirmation.

Accessioning comprises the initial integration of a sample within a lab's system. The process checks if the sample was properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any required data entries absent in an electronic chain of custody framework.

Screening executes a preliminary, rapid assessment for drugs of abuse. Although Screening is economical in ruling out drug use in most samples, courts demand a confirmed positive screen for it to be permissible. Samples indicating a positive result during Screening require further confirmation.

If a test reveals a positive result in the Screening phase, additional hair is extracted from the initial sample for Extraction. This stage involves pulling drugs out of hair at a decreased concentration compared to other styles such as urine or saliva, illustrating why hair drug testing stands as the toughest method.

GC/MS, GC/MS/MS, or LC/MS/MS methods verify any positive Screening outcomes during Confirmation. All presumptive positive samples undergo washing ahead of confirmation as necessary. CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards regulate the complete process from Accessioning through Confirmation.

Advantages of hair drug testing:

• Extended detection period: Hair tests identify drug activity up to 90 days, in contrast to urine tests, which have a narrower detection period.
• Challenging to falsify: The likelihood of deceiving a hair drug test is minimal, thus ensuring greater result accuracy.
• Offers chronological data: It can depict continuous drug usage trends over time, not solely recent use.

Limitations:

• Incapable of identifying recent use: It requires around 5-7 days for drugs to be observable in hair.
• Expense: Generally, hair drug tests surpass other drug-testing methods in cost.
• Result discrepancies: Aspects like hair color and individual hair growth differences might influence drug metabolite concentration in the hair.

Note: Commonly known as "hair follicle tests", the analysis targets the hair strand rather than the follicle beneath the scalp
