Hair Follicle Drug Testing - Newfane, VT

What it is, How it works

Hair testing is recognized as a potent method for identifying alcohol and drug consumption. Hair offers a longitudinal view of drug and alcohol history by capturing biomarkers within the fibers of the hair as it grows. When gathered near the scalp, hair can offer a detection window of up to roughly 3 months for alcohol and drugs. It's easy to collect, relatively hard to tamper with, and convenient to send.

A sample of 1.5 inches from approximately 200 strands of hair (comparable to a #2 pencil's thickness) near the scalp will yield 100mg of hair, which is the desired sample size for both screening and confirmation. For EtG, extra panels, or tests exceeding 10 panels, a sample of 150mg is advisable. The specimen should ideally be weighed using a jeweler’s scale. If scalp hair is absent, a similar quantity of body hair can be collected. When mentioning head hair, it pertains only to scalp hair. Body hair encompasses all other hair types (like facial, axillary, etc.).

Process Overview

The laboratory process for analyzing a drug test result consists of four main stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first step where a sample is introduced into a laboratory’s system. This step verifies the sample was sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data entry that's not supplied by an electronic chain of custody.

Screening involves a preliminary quick evaluation for drugs. While it's a cost-efficient way to exclude drug usage in most samples, a positive screen must be verified for court acceptability. Any samples that are initially positive in Screening need subsequent confirmation.

If a sample shows a presumptive positive during Screening, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are extracted from hair in concentrations much lower than other methods (such as urine or oral fluid), making hair drug screening the most challenging methodology.

Confirmation of any positive from the screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing as necessary before confirmation. The entire laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair standard and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can reveal drug usage for up to 90 days, whereas urine tests have a shorter detection period.
• Difficulty to cheat: Hair drug tests are very difficult to evade, enhancing the accuracy of results.
• Provides historical data: They can showcase a pattern of drug use over an extended timeline, not merely recent use.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair approximately 5-7 days post-ingestion.
• Cost: Hair drug tests tend to be more costly compared to other drug testing techniques.
• Variations in results: The concentration of drug metabolites in hair can be influenced by factors like hair color and individual differences in hair growth.

Note: Although often referred to as "hair follicle tests", the actual analysis is conducted on the hair strand, not the follicle beneath the scalp.
