Hair Follicle Drug Testing - Mclemoresville, TN

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol use. Hair holds a long-term record of substances by embedding biomarkers in its growing strands. Collected near the scalp, hair offers a detection period of approximately three months for alcohol and other drugs. The collection process is straightforward, difficult to tamper with, and easy to transport.

A sample measuring 1.5 inches with around 200 hair strands (similar to the thickness of a #2 pencil) from near the scalp results in 100mg, which is ideal for testing and confirmation. For EtG, add-ons, and tests exceeding 10 panels, 150mg of hair is advised. It is suggested to weigh the specimen using a jeweler’s scale. If scalp hair cannot be obtained, an equivalent amount of body hair is acceptable. When we mention head hair, it pertains to scalp hair only, while body hair encompasses all other types (e.g., facial, axillary).

Process Overview

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

Accessioning is the initial step of processing a sample into a lab's system. This step ensures the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry absent in an electronic chain of custody system.

Screening provides a preliminary assessment for drug presence. While Screening offers a cost-effective approach to dismiss drug use in most samples, a confirmed positive result is necessary for legal admissibility. Presumptively positive samples from Screening require secondary confirmation.

For presumptively positive samples during Screening, additional hair is extracted from the initial sample for the Extraction process. Drugs are extracted from hair at lower concentrations than in other techniques (such as urine or oral fluid), explaining why hair drug testing is particularly challenging.

Confirmation of positive screening outcomes is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation as needed. The laboratory steps from Accessioning to Confirmation are scrutinized under both the CAP (College of American Pathologists) Hair specifications and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests which offer a shorter detection window.
• Hard to falsify: Cheating a hair drug test is notably challenging, enhancing result reliability.
• Yields historical data: It reveals a drug use pattern over time, beyond just recent consumption.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug tests generally cost more than alternative testing methods.
• Result variations: Factors such as hair color and individual differences in hair growth can influence drug metabolite concentration in hair.

Note: Commonly labeled as "hair follicle tests", the analysis actually examines the hair strand, not the follicle beneath the scalp.
