Hair Follicle Drug Testing - Troy, MN

What it is, How it works

Hair testing is acknowledged as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drug intake by embedding biomarkers within the strands of growing hair. When collected near the scalp, hair can offer up to a 3-month detection timeframe for alcohol and drugs. The collection process for hair is straightforward, complicating adulteration, and is convenient for shipping.

A 1.5-inch sample consisting of roughly 200 hair strands (comparable to a #2 pencil's diameter) taken close to the scalp provides 100mg of hair, which is the optimal sample size for screening and confirmation. For EtG, additional testing, and tests greater than 10 panels, a specimen of 150mg is advised. It's recommended to use a jeweler’s scale for weighing the specimen. If scalp hair is not available, a similar quantity of body hair can be used. "Head hair" refers solely to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).

Process Overview

The lab processing of a drug test result includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning comprises the initial handling of a sample into a laboratory's system. This stage involves confirming that the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing additional data entry tasks not covered by an electronic chain of custody system.

Screening entails a preliminary rapid examination for drugs of abuse. While Screening provides a cost-effective approach to excluding drug use in most samples, a positive result requires confirmation to be considered legally valid. All samples yielding presumptive positive results during Screening must undergo secondary confirmation.

Should a sample test presumptively positive during the Screening phase, additional hair is taken from the initial sample and readied for Extraction. This phase involves extracting drugs from hair at a much lower concentration than other methods (e.g., urine or oral fluid), which explains why hair drug screening is notably challenging to execute.

Confirmation of any positive screen result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptive positive undergo washing prior to confirmation if necessary. The entire lab process, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation according to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection span.
• Challenging to deceive: It is highly challenging to falsify a hair drug test, enhancing the accuracy of results.
• Provides usage history: It can illustrate a pattern of drug use over a duration, not just recent consumption.

Limitations:

• Incapable of detecting recent use: It requires about 5-7 days for drugs to be identifiable in hair.
• Expense: Hair drug tests are generally pricier than other drug testing modalities.
• Outcome variations: Elements such as hair color and personal differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Frequently termed "hair follicle tests", the assessment analyzes the hair strand itself, not the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
