Hair Follicle Drug Testing - Manifest, LA

What it is, How it works

Hair testing is now recognized as an influential method for detecting drug and alcohol consumption. Hair provides a comprehensive timeline of alcohol and other substance use by encapsulating biomarkers within the strand's fibers as it grows. When collected near the scalp, hair can offer a detection span of up to roughly three months for alcohol and other substances. Hair collection is straightforward, somewhat resistant to tampering, and convenient to transport.

A 1.5-inch segment containing roughly 200 hairs (comparable to a #2 pencil in thickness) nearest the scalp yields 100mg of hair, which is considered the optimal sample for both screening and confirmation. For EtG add-ons or tests exceeding ten panels, 150mg of the sample is preferable. Utilizing a jeweler’s scale for weighing the specimen is suggested. Should scalp hair be unavailable, an equivalent quantity of body hair can be gathered. By head hair, we imply exclusively scalp hair, while body hair encompasses all other types (e.g., facial, axillary).

Process Overview

The laboratory processing of a drug test outcome encompasses four principal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial incorporation of a specimen into the laboratory's framework. This stage ensures that the sample was sealed and transported correctly, assigns an arbitrary LAN (Laboratory Accessioning Number), and concludes any extra data input not accounted for by an electronic chain of custody application.

Screening consists of an initial, rapid assessment for abusive substances. Although Screening efficiently eliminates the presence of drugs in most specimens, a positive screen necessitates confirmation for legal admissibility. Samples deemed presumptively positive during Screening require further confirmation.

In cases where Screening results are presumptively positive, additional hair is retrieved from the primary specimen for Extraction. This stage extracts drugs from hair at markedly lower concentrations than those in alternative techniques (e.g., urine or saliva), rendering hair drug screening as the most challenging methodology.

Confirmation of any positive Screening is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation if required. The entire laboratory procedure from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation 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 that have a shorter timeframe.
• Difficulty in manipulation: Cheating a hair drug test is notably challenging, ensuring more precise results.
• Offers historical insights: It can portray a pattern of substance use over time, rather than just recent consumption.

Limitations:

• Inability to detect recent usage: It generally takes 5-7 days for substances to become traceable in hair.
• Expense: Hair drug tests tend to be costlier compared to other testing methods.
• Variability in outcomes: Aspects like hair color and individual differences in hair growth can influence drug metabolite concentration in hair.

Note: Commonly termed "hair follicle tests", the analysis examines the hair strand rather than the follicle beneath the scalp.
