Hair Follicle Drug Testing - Avoca, IN

What it is, How it works

Hair analysis has evolved into a critical method for identifying substance use, including drugs and alcohol. Hair contains a lasting record of substance intake by preserving biomarkers within the strands as they grow. Collecting a sample close to the scalp can offer a detection range of up to three months for alcohol and other substances. Hair is easy to gather, challenging to tamper with, and simple to transport.

An optimal sample consists of a 1.5-inch length of roughly 200 hair strands (comparable to the diameter of a #2 pencil) nearest to the scalp, yielding around 100mg. This quantity is ideal for both initial screenings and confirmatory tests. For EtG, additional analyses, or tests exceeding ten panels, a quantity of 150mg is advisable. It is suggested to measure the specimen using a jeweler’s scale. If scalp hair is unavailable, an equivalent volume of body hair may be used. References to head hair pertain specifically to scalp hair, while body hair includes all other types (facial, axillary, etc.).

Process Overview

The laboratory procedure for processing drug test outcomes consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage, where the sample is integrated into the lab's system, ensuring that the sample is properly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry absent from the electronic chain of custody.

Screening provides an initial, rapid assessment for substances of abuse. While a cost-efficient approach for negating drug usage in most samples, a positive result from Screening necessitates confirmation for legal admissibility. Samples that yield presumptive positives require subsequent confirmation.

In cases of presumptive positivity in the Screening phase, additional hair is taken from the initial sample and readied for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

Confirmation of any positive result obtained during screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation as required. The complete laboratory method from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair criteria and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection range: Hair drug tests can reveal drug consumption for up to 90 days, unlike urine tests, which have a more limited detection period.
• Challenging to manipulate: Hair drug tests are difficult to deceive, enhancing result reliability.
• Offers historical insight: It highlights drug use patterns over time, beyond immediate past use.

Limitations:

• Does not detect recent intake: It requires approximately 5-7 days post-consumption for substances to be traceable in hair.
• Expense: Hair drug tests tend to be pricier than other testing methodologies.
• Result variability: Factors like hair color and individual hair growth differences can influence drug metabolite levels in hair.

Note: Though commonly termed "hair follicle tests," the analysis targets the hair strand, excluding the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair testing in Avoca, IN, excels against traditional urine tests by offering superior detection capabilities. While urine only detects recent consumption, hair testing gives a broader view of substance use history.
