Hair Follicle Drug Testing - Yale, OK

What it is, How it works

Hair analysis is recognized as an effective method for detecting the consumption of substances like drugs and alcohol. Hair retains a comprehensive history of substance usage, thanks to the encapsulation of biomarkers within the hair strand's fibers as they grow. When hair is collected near the scalp, it can offer an approximate three-month detection span for alcohol and other substances. Hair collection is straightforward, challenging to tamper with, and easy to transport.

A sample measuring 1.5 inches, comprising around 200 hair strands (roughly equivalent to the thickness of a #2 pencil) nearest to the scalp will provide 100mg of hair – the optimal amount for both screening and confirmation. For EtG, auxiliary testing, and tests exceeding 10 panels, it is advised to gather 150mg of the sample. It's recommended to measure the specimen using a jeweler's scale. If scalp hair isn't available, an equivalent amount of body hair can be collected. When referring to head hair, it pertains exclusively to scalp hair. Body hair encompasses all other types of hair (such as facial, axillary, etc.).

Process Overview

The laboratory analysis of a drug test result incorporates four essential steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a sample is integrated into a laboratory's system. This involves ensuring the sample was sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not included by an electronic chain of custody system.

Screening is an initial, expedient assessment for drugs of abuse. Although Screening offers a cost-efficient method to exclude drug consumption in most samples, a positive screening must be corroborated for legal admissibility. Any samples showing presumptive positivity during Screening require secondary confirmation.

Should a sample show presumptive positivity in the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. During this phase, drugs are isolated from hair at much lower concentrations than in other methodologies (e.g., urine or oral fluid), making hair drug screening the most intricate methodology to conduct.

Confirmation of any positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation if necessary. The comprehensive laboratory process, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection duration: Hair drug tests can reveal drug use for as long as 90 days, whereas urine tests have a shorter detection timeframe.
• Challenging to deceive: Hair drug tests are extremely difficult to manipulate, ensuring more precise results.
• Reveals usage history: They can illustrate a pattern of drug use over time rather than just recent consumption.

Drawbacks:

• Inability to detect recent intake: It requires about 5-7 days for drugs to be noticeable in hair.
• Expense: Hair drug tests typically incur higher costs compared to other testing methods.
• Result variability: Elements such as hair color and individual differences in hair growth can influence drug metabolite concentrations in the hair.

Note: Although commonly termed "hair follicle tests", the test analyzes the hair strand, not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Yale, OK
When comparing hair follicle testing to traditional urine testing, several advantages emerge.
