Hair Follicle Drug Testing - Trimble, TN

What it is, How it works

Hair testing has emerged as a robust method for detecting drug and alcohol consumption. Hair captures a comprehensive history of substance use by embedding biomarkers within the fibers of each growing strand. When sourced near the scalp, hair can offer roughly a 3-month detection period for both alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and can be easily transported.

A sample measuring 1.5 inches, consisting of about 200 hair strands (equivalent to a #2 pencil's diameter) nearest to the scalp, yields 100mg, which is optimal for both screening and confirmation. For EtG, additional tests, and tests above 10 panels, a specimen of 150mg is advised. We suggest using a jeweler’s scale to weigh the sample. If scalp hair cannot be collected, a comparable quantity of body hair should be gathered. "Head hair" pertains solely to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).

Process Overview

The core stages in laboratory processing of a drug test comprise Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the sample's initial entry into the lab’s system. This process includes ensuring the proper sealing and shipment of the sample, allocating a random LAN (Laboratory Accessioning Number), and inputting any additional information not covered by an electronic chain of custody.

Screening conducts an expedited analysis of potential drug misuse. Though Screening is cost-efficient for disqualifying drug use across most samples, a positive indication must be authenticated to be valid in legal settings. Any samples that test presumptively positive during Screening necessitate secondary validation.

Should Screening yield a presumptive positive, further hair is taken from the starting specimen for the Extraction phase. Here, drugs are extracted from hair in much lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting hair drug testing as the most challenging method to execute.

Positive results from screening are validated using GC/MS, GC/MS/MS or LC/MS/MS techniques. Prior to confirmation, all samples testing presumptively positive undergo washing as appropriate. The complete laboratory procedure from Accessioning through Confirmation is assessed under the CAP (College of American Pathologists) Hair designation as well as ISO / IEC 17025 accreditation.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use extending up to 90 days, whereas urine tests have shorter detection periods.
• Challenging to manipulate: The accuracy of hair drug tests is higher due to the difficulty in falsifying results.
• Delivers historical patterns: It provides insights into a chronology of drug use, rather than just recent occurrences.

Drawbacks:

• Cannot identify recent intake: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests are typically costlier compared to other testing methods.
• Result variability: Variables such as hair color and individual hair growth differences can impact drug metabolite concentrations in the hair.

Note: Often called "hair follicle tests", the analysis is of the hair strand itself, not the follicle beneath the scalp.
