Hair Follicle Drug Testing - Cook, MN

What it is, How it works

Hair analysis has emerged as an effective technique for identifying drug and alcohol consumption. Hair captures a historical record by embedding biomarkers within the strands as they grow. When collected proximal to the scalp, this method offers a detection period extending up to roughly 90 days for alcohol and various drugs. Hair collection is straightforward, not easily tampered with, and convenient for shipping.

A sample size of 1.5 inches encompassing approximately 200 strands (roughly akin to a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal amount for both screening and confirmation processes. For EtG, supplementary tests, or panels exceeding 10, 150mg of hair is advised. Utilizing a jeweler’s scale to measure the specimen is suggested. In the absence of scalp hair, a comparable quantity of body hair can be used. Head hair pertains solely to scalp hair, whereas body hair includes all other types (facial, axillary, etc.).

Process Overview

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

Accessioning entails the initial integration of a sample into the laboratory’s system. This phase ensures the sample was securely sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data entries not covered by an electronic chain of custody.

During Screening, an initial rapid assessment for illicit substances is conducted. While Screening serves as a budget-friendly strategy to discount drug use in most samples, any positive results must be corroborated for legal acceptability. Samples presumptively positive during Screening necessitate further confirmation.

Should a sample indicate a presumptive positive in Screening, additional hair is isolated from the initial sample for the Extraction phase. Here, drugs are isolated from hair at significantly lesser concentrations than in other methods (e.g., urine or saliva), rendering hair drug screening the most challenging methodology to execute.

Confirmation of any positive screening outcomes utilizes GC/MS, GC/MS/MS, or LC/MS/MS technologies. All presumptively positive samples undergo cleansing prior to confirmation as necessary. The complete lab procedure from Accessioning to Confirmation undergoes review in alignment with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation norms.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use up to 90 days back, unlike urine tests with shorter detection periods.
• Challenging to manipulate: Hair drug tests are hard to falsify, ensuring greater accuracy in results.
• Chronological data: It offers insights into drug usage patterns over time, not just recently.

Limitations:

• Incapable of showing recent usage: Drugs require 5-7 days to become detectable in hair.
• Expense: Hair drug tests tend to cost more than alternative drug testing techniques.
• Result discrepancies: Hair color and individual differences in growth can influence drug metabolite concentration in hair.

Note: Although commonly referred to as "hair follicle tests", the test examines the hair strand rather than the follicle under the scalp
