Hair Follicle Drug Testing - Richwood, WI

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and substance use by encapsulating biomarkers within the fibers of the growing strand. When acquired near the scalp, hair can reveal up to roughly a 3-month detection period for substances and alcohol. Hair collection is straightforward, challenging to tamper with, and convenient for shipping.

A 1.5-inch section comprising about 200 hair strands (roughly the diameter of a #2 pencil) nearest the scalp yields 100mg of hair, which is optimal for screening and confirmation. For EtG, additional tests, and samples exceeding 10 panels, a 150mg specimen is recommended. Utilizing a jeweler’s scale to weigh the specimen is advisable. Should scalp hair be unavailable, a comparable volume of body hair may be utilized. References to head hair pertain exclusively to scalp hair, whereas body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The drug test result laboratory processing comprises four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary sample processing into a laboratory’s system. This process verifies that the sample was properly sealed and transported, assigns an arbitrary LAN (Laboratory Accessioning Number), and completes any supplementary data entry not managed by an electronic chain of custody system.

Screening offers an initial rapid assessment for drugs of abuse. Although Screening is an economical means to exclude drug usage in most samples, any positive results necessitate confirmation to be legally admissible. Samples with presumptive positives in Screening require secondary confirmation.

In instances where Screening suggests a positive result, additional hair is isolated from the original specimen for Extraction. At this stage, substances are extracted from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), highlighting hair drug screening's elevated complexity.

Confirmation for all positive screen results is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if needed. The complete laboratory procedure, from Accessioning to Confirmation, undergoes evaluation according to both CAP (College of American Pathologists) Hair guidelines and accreditation to ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Prolonged detection period: Hair drug tests can identify drug use for up to 90 days, whereas urine tests exhibit a briefer detection window.
• Challenge to deceive: Hair drug tests are highly resistant to tampering, resulting in more precise outcomes.
• Delivers historical insights: It delineates a drug use pattern over time, beyond just recent consumption.

Drawbacks:

• Inability to pinpoint recent use: Detectability in hair requires approximately 5-7 days.
• Expense: Hair drug testing tends to be costlier than alternative drug testing methods.
• Result variability: Variables like hair color and individual growth variations can influence metabolite concentrations in hair.

Note: Although commonly termed "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp.
