Hair Follicle Drug Testing - Lawsonia, MD

What it is, How it works

Hair tests are recognized as a significant method for identifying substance and alcohol consumption. The structure of hair retains markers of alcohol and drugs within the hairs as they grow, providing a comprehensive timeline. Collected from the scalp's proximity, hair offers up to a three-month detection period for both substances. It's easy to collect, less vulnerable to tampering, and straightforward to send.

A 1.5-inch sample of roughly 200 hair strands (equivalent to a #2 pencil) near the scalp yields around 100mg of hair, ideal for both screening and verification. For EtG, added tests, and/or in cases where the panel exceeds 10, a 150mg sample is advisable. Use a jeweler’s scale for weighing. Should scalp hair be inaccessible, a similar volume of body hair may be utilized. In reference to head hair, it pertains exclusively to scalp hair. Body hair includes all other hair categories (facial, axillary, etc.).

Process Overview

The procedure for processing a drug test in a lab involves Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step, integrating the specimen into the lab’s database. This involves checking that the specimen was appropriately sealed and dispatched, assigning a LAN (Laboratory Accessioning Number), and completing any manual data entry missing from an electronic custody chain.

Screening provides an initial evaluation for substance misuse. It is economical for eliminating substance presence in most cases; however, if a screen shows positive, it needs confirmation for validity in legal contexts. Any items preliminarily positive in Screening necessitate further confirmation.

Should a sample show preliminary positivity during Screening, additional hair is extracted from the original and readied for Extraction. In this phase, drugs are isolated from hair in less concentration compared to other techniques (e.g., urine or saliva), rendering hair drug testing particularly challenging.

Confirmation of a positive Screening result uses GC/MS, GC/MS/MS, or LC/MS/MS techniques. All preliminary positive samples undergo cleaning before confirmation when needed. The entire cycle from Accessioning to Confirmation is conducted under scrutiny via the CAP (College of American Pathologists) Hair standard and is compliant with ISO / IEC 17025 regulations.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can track substance use for up to 90 days, unlike urine tests, which have shorter detection spans.
• Hard to falsify: Manipulating hair drug tests is challenging, enhancing result reliability.
• Shows usage timeline: Delivers a drug usage pattern over an extended time, not just immediate use.

Limitations:

• Doesn't detect recent consumption: There's a 5-7 day gap before drugs are traceable in hair.
• Expense: Hair drug testing generally incurs higher costs than other testing forms.
• Result variability: Differences like hair color and growth rates can influence drug metabolite concentrations in hair.

Note: Often named "hair follicle tests", the actual test analyzes the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle testing to traditional urine testing in Lawsonia, MD, the former stands out due to increased accuracy and reliability. Hair tests offer a longer detection period, up to 90 days, maximizing the capture of substance use details.
