Hair Follicle Drug Testing - Riverwoods, IL

What it is, How it works

The utilization of hair testing has emerged as an effective means for uncovering substance abuse. Hair captures a long-lasting record of alcohol and drug usage by preserving markers within the strands of hair as they grow. When sampled close to the scalp, hair offers around a 3-month detection period for drugs and alcohol. This method is straightforward to obtain, relatively resistant to tampering, and easy to transport.

A sample measuring 1.5 inches and consisting of approximately 200 hairs (comparable to the thickness of a #2 pencil) closest to the scalp provides 100mg of hair, which is the ideal quantity for both screening and confirmation. For EtG, additional analyses, or tests exceeding 10 panels, 150mg is preferable. We advise using a jeweler’s scale for weighing the specimen. Should scalp hair be unavailable, an equivalent quantity of body hair might be utilized. "Head hair" refers exclusively to hair on the scalp, while "body hair" includes all other types (facial, axillary, etc.).

Process Overview

The laboratory analysis of a drug test result comprises four critical stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the preliminary integration of a sample into a lab’s system. This procedure entails verifying the sample’s proper sealing and shipment, issuing an arbitrary LAN (Laboratory Accessioning Number), and finishing any supplementary data entry absent from an electronic chain of custody protocol.

Screening involves an initial rapid examination for drug abuse indicators. Although Screening provides an economical method for eliminating drug usage in the bulk of samples, any positive screens must be verified to be permissible in a legal setting. Presumptively positive samples from Screening require another round of confirmation.

For samples that test presumptively positive during Screening, additional hair is gathered from the initial specimen and readied for Extraction. In Extraction, drugs are withdrawn from hair at significantly lower concentrations than found with alternative techniques (such as urine or saliva), highlighting the complexities of hair drug examination.

Confirmation of any positive preliminary findings is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples presumptively positive undergo washing prior to confirmation if deemed necessary. The complete laboratory sequence from Accessioning through Confirmation is examined under the CAP (College of American Pathologists) Hair designation, paired with adherence to ISO / IEC 17025 standards.

Benefits of hair drug assessments:

• Extended detection duration: Hair drug assessments can reflect drug consumption for up to 90 days, as opposed to urine assessments, which offer a briefer duration.
• High difficulty to manipulate: Manipulating hair drug results is notably challenging, thereby enhancing the accuracy.
• Historical insights: Offers a timeline of drug consumption patterns over an extended timeframe, rather than capturing only recent activity.

Constraints:

• Recent usage detection limits: Drugs require roughly 5-7 days to become traceable in hair.
• Expense: Hair assessments typically incur greater costs compared to other methodologies.
• Result variability: Differences in hair color and personal hair growth can influence the metabolite concentration in hair.

Note: The commonly used term "hair follicle tests" is misleading; the test evaluates the hair strand rather than the follicle beneath the scalp.
