Hair Follicle Drug Testing - Onancock, VA

What it is, How it works

Hair testing is increasingly recognized as an effective means of detecting the use of drugs and alcohol. Hair maintains a long-term log of alcohol and drug use by embedding biomarkers in the strands of growing hair. When collected close to the scalp, hair can provide up to roughly a 3-month detection window for alcohol and drug presence. Hair is easy to collect, moderately challenging to tamper with, and straightforward to transport.

A 1.5-inch sample comprising approximately 200 strands of hair (around the thickness of a #2 pencil) close to the scalp will yield 100mg of hair, the perfect sample amount for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advisable. We suggest weighing the sample on a jeweler’s scale. If scalp hair is not available, a comparable amount of body hair can be collected. In the context of head hair, we refer to scalp hair exclusively. Body hair encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test consists of four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a laboratory's system. This step includes confirming that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any other data entry not covered by an electronic chain of custody system.

Screening involves an initial rapid check for the presence of drugs. While this step is a cost-effective method to rule out drug usage in most samples, a positive screen must be verified for it to be admissible in legal contexts. Any samples that return a presumptive positive in Screening require a further confirmation.

If a sample is indicated as positive in the Screening phase, extra hair is extracted from the original sample and prepared for Extraction. During this phase, drugs are extracted from hair at a significantly lower concentration than with other methods (e.g., urine or oral fluid), which is why hair drug screening represents the most challenging method to perform.

Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples are washed prior to confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair accreditation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests have the ability to detect drug usage for up to 90 days, unlike urine tests that offer a shorter detection period.
• High resistance to tampering: Cheating a hair drug test is quite difficult, ensuring the results are more reliable.
• Delivers longitudinal data: It reveals a pattern of drug usage over an extended timeframe, not just recent instances.

Limitations:

• Cannot detect immediate use: It takes about 5-7 days for drugs to show up in hair.
• Cost: Hair drug tests often come with a higher price tag compared to other drug testing methods.
• Result variability: Factors like hair color and individual differences in hair growth can impact the concentration of drug metabolites in the hair.

Note: Although commonly referred to as "hair follicle tests", the test itself evaluates the hair strand, not the follicle under the scalp.
