Hair Follicle Drug Testing - Polk, NE

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair serves as a record of long-term alcohol and drug use by embedding biomarkers within the fibers of hair as it grows. When taken close to the roots, hair can reveal a usage pattern up to roughly a three-month period for alcohol and other substances. Hair samples are easy to collect, challenging to tamper with, and straightforward to transport.

A strand segment of 1.5 inches comprising about 200 hairs (roughly equivalent to the width of a #2 pencil) near the roots will yield 100mg, which is the preferred quantity for both initial testing and subsequent validation. For EtG analysis, additional options, and/or tests exceeding ten panels, a specimen of 150mg is advisable. It is suggested to determine the specimen's weight using a jeweler’s scale. Should scalp hair be inaccessible, a similar quantity of body hair can be obtained. In context, head hair refers only to scalp hair, while body hair includes all other types (like facial, underarm, etc.).

Process Overview

The four key procedures involved in processing a drug test in a laboratory are: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the preliminary integration of a sample into the lab's processes. This step confirms the sample's proper sealing and delivery, generates a random LAN (Laboratory Accessioning Number), and finalizes additional data input not included in an electronic chain of custody system.

Screening entails an initial, speedy examination for drugs of abuse. Although Screening is a cost-efficient method to eliminate drug use in most specimens, a positive outcome must be validated to support legal admissibility. All presumptively positive samples in Screening necessitate a secondary verification.

When a sample is potentially positive during the Screening phase, additional hair is extracted from the initial sample and prepared for the Extraction phase. In this stage, drugs are retrieved from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), which accounts for the complexity of hair drug screening.

Any positive result from screening is confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples predicted to be positive are cleansed before confirmation as necessary. The laboratory process from Accessioning to Confirmation undergoes evaluation under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests detect drug use for up to 90 days, unlike urine tests with shorter detection times.
• High resistance to tampering: Cheating a hair drug test is quite challenging, leading to more reliable results.
• Historical insight: The test reveals a history of drug use over time, not just recent consumption.

Limitations:

• Inability to identify recent use: Drugs become detectable in hair roughly 5-7 days after use.
• Higher cost: Hair drug testing is typically costlier than alternative drug testing methods.
• Result variability: Factors like hair color and individual hair growth differences can impact drug metabolite levels in hair.

Note: Commonly described as "hair follicle tests," the analysis targets the hair strand rather than the follicle beneath the skin.
