Hair Follicle Drug Testing - Kingsport, TN

What it is, How it works

Hair testing is widely regarded as an effective approach for identifying drug and alcohol consumption. Hair offers an extended timeline of substance use by embedding biomarkers within the strands as they grow. When hair is clipped close to the root, it can provide an estimated 3-month timeframe to detect alcohol and other drugs. Collection is straightforward, tampering is relatively challenging, and transportation is hassle-free.

A sample consisting of 1.5 inches of hair and around 200 strands (approximately equivalent to the thickness of a #2 pencil) nearest to the scalp yields about 100mg, which is perfect for both screening and confirming results. For EtG, supplementary tests, or tests covering more than 10 panels, a sample of 150mg is advocated. It's advisable to measure the sample's weight using a jeweler's scale. If scalp hair is unavailable, the equivalent volume of body hair is acceptable. References to head hair imply exclusively scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The essential stages in lab processing for deriving a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial handling of a sample into the lab's records. This phase assures the sample's proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and completes data entry that isn't covered by an electronic chain of custody system.

Screening entails a preliminary assessment for substance misuse. Screening is economically efficient for ruling out drug use for most samples, yet a positive screen mandates confirmation to be valid in legal settings. Any samples that yield a presumptive positive in Screening must undergo a subsequent confirmation.

If a sample results in a presumptive positive during Screening, additional hair is extracted from the existing specimen for the Extraction process. Drugs are extracted from hair at substantially lower levels compared to other methods (e.g., urine, oral fluid), which makes hair drug screening one of the most challenging methods.

Confirmation for any positive Screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The comprehensive laboratory procedure, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation in accordance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can ascertain drug usage for up to 90 days, contrasting with urine tests that offer a shorter detection period.
• Hard to manipulate: Attempting to bypass a hair drug test is notably difficult, thus ensuring more reliable outcomes.
• Reveals historical trends: It exposes a pattern of substance use over time and not just recent consumption.

Limitations:

• Unable to identify recent consumption: It usually takes about 5-7 days for substances to become traceable in hair.
• Expenditure: Hair drug tests are often pricier than other testing methods.
• Result variations: Elements like hair color and personal hair growth rates can influence the levels of drug metabolites in hair.

Note: Often labeled as "hair follicle tests", the test targets the hair strand and not the follicle beneath the scalp
