Hair Follicle Drug Testing - Buffalo, WI

What it is, How it works

Hair testing has emerged as an effective means for detecting drug and alcohol use. Hair retains long-term markers of alcohol and drug exposure by embedding biomarkers within the fibers of the hair strand as it grows. If cut near the scalp, hair can reveal an approximate 3-month history for alcohol and drug use. Hair collection is straightforward, relatively tamper-proof, and convenient to transport.

A 1.5-inch segment consisting of roughly 200 hair strands (around the size of a #2 pencil) nearest to the scalp yields about 100mg of hair, which is the optimal sample size for both screening and validation. For EtG, additional assessments, or tests exceeding 10 panels, it is advisable to collect 150mg of the sample. We suggest using a jeweler's scale for specimen measurement. Should scalp hair be inaccessible, a corresponding quantity of body hair may be obtained. The phrase "head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other hair types (such as facial or axillary hair).

Process Overview

The laboratory processing of drug test results includes four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial registration of a sample within a lab system. It involves checking that the sample was properly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and inputting any extra data not captured by an electronic chain of custody system.

Screening carries out a preliminary rapid assessment for drug compounds. Although Screening is a cost-efficient approach to exclude drug use for the bulk of samples, positive findings require further validation to be legally acceptable. Any samples flagged as presumptively positive during the Screening stage necessitate a subsequent confirmation.

Once a sample is tentatively positive at the Screening phase, additional hair is extracted from the original specimen for the Extraction phase. Here, drugs are isolated from hair at much lower concentrations compared to other techniques (e.g., urine or oral fluid), making hair drug testing a notably challenging procedure.

Confirmation of any positive Screening outcomes is performed through methods like GC/MS, GC/MS/MS, or LC/MS/MS. All tentative positive samples undergo washing before confirmation if needed. The comprehensive lab procedure, from Accessioning to Confirmation, is conducted under the CAP (College of American Pathologists) Hair designation and follows the accreditation standards of ISO/IEC 17025.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests have a detection window of up to 90 days, exceeding that of urine tests.
• Difficult to falsify: Cheating a hair drug test is highly challenging, ensuring more reliable results.
• Reveals usage patterns: It can show a timeline of drug usage, rather than just recent consumption.

Limitations:

• Inability to detect recent usage: Drugs take approximately 5-7 days to be traceable in hair.
• Expense: Hair drug tests are typically more costly than other testing techniques.
• Result variability: Factors like hair color and personal differences in hair growth can influence drug metabolite levels in hair.

Note: The term "hair follicle tests" commonly used is somewhat misleading, as the analysis focuses on the hair strand rather than the hair follicle beneath the scalp.
