Hair Follicle Drug Testing - Woodrow, TX

What it is, How it works

The use of hair for testing is now regarded as a robust method for identifying substance and alcohol consumption. Hair captures a prolonged record of alcohol and drug usage by embedding biomarkers within the growing hair fibers. When hair is clipped near the scalp, it can reveal drug and alcohol usage over a detection period that can extend up to around three months. The collection of hair is straightforward, relatively hard to tamper with, and simple to send.

Acquiring a 1.5-inch segment of roughly 200 hair strands (about the dimensions of a #2 pencil) nearest to the scalp will result in a 100mg sample, which is ideal for both screening and confirmation. For EtG screenings, extensions, and/or tests exceeding 10 panels, a recommendation is to use 150mg of the sample. It is advised to assess the specimen's weight using a jeweler’s scale. Should scalp hair be inaccessible, a similar amount of body hair can be harvested. When talking about head hair, it denotes only the scalp hair. Body hair encompasses all other variants (face, underarm, etc.).

Process Overview

The procedure of processing a drug test outcome in a lab comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial handling of a specimen within a laboratory's apparatus. This procedure includes confirming that the specimen was appropriately sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any supplementary data input absent in an electronic chain of custody system.

Screening entails a preliminary swift examination for drug abuse. Although Screening offers an economical approach to exclude drug use in most specimens, a positive outcome necessitates validation to be admissible in legal settings. Any sample that tests presumptively positive in Screening requires subsequent Confirmation.

Should a sample test presumptively positive in the Screening, additional hair is extracted from the initial specimen and made ready for Extraction. During this process, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or saliva), which is why hair drug testing is the most challenging methodology to conduct.

Confirmation of a positive Screening result is performed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumed positive samples undergo washing before Confirmation if necessary. From Accessioning to Confirmation, the overall laboratory process is supervised under both the CAP (College of American Pathologists) Hair designation and the recognition to ISO / IEC 17025 benchmarks.

Advantages of hair drug testing:

• Prolonged detection span: Hair drug screenings can recognize substance use up to 90 days back, unlike urine tests which have a shorter detection range.
• Hard to manipulate: Hair drug screenings are notably tough to cheat, enhancing result accuracy.
• Yields historical patterns: It offers an insight into the drug use trend over time, not just recent occurrences.

Limitations:

• Can't identify immediate use: Approximately 5-7 days are required for drugs to be traceable in hair.
• Expense: Hair drug screenings tend to be more costly than other drug testing methods.
• Result variability: Elements such as hair color and personal differences in hair growth can impact drug metabolite concentrations within the hair.

Note: While frequently called "hair follicle tests", the examination analyses the hair strand itself, not the scalp-located hair follicle
