Hair Follicle Drug Testing - West Laurel, MD

What it is, How it works

The utilization of hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. Hair offers an extended timeline of alcohol and drug activity by capturing biomarkers within the fibers of the hair as it grows. When taken close to the scalp, it can provide a detection period of roughly three months for alcohol and drug presence. The collection of hair is straightforward, less prone to tampering, and easy to transport.

A 1.5-inch section containing around 200 hair strands (roughly the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is considered an optimal sample for preliminary testing and confirmation. For tests such as EtG or tests beyond 10 panels, a 150mg sample is suggested. It's advised to weigh the sample on a jeweler’s scale. If scalp hair cannot be obtained, an equivalent quantity of body hair is acceptable. When mentioning head hair, specifically, it pertains only to scalp hair. Body hair encompasses all other hair types (e.g., facial, axillary, etc.).

Process Overview

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

Accessioning entails the initial integration of a sample into a laboratory’s system, which involves verifying that the sample was appropriately sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not recorded by an electronic chain of custody system.

Screening involves a preliminary assessment for drugs of abuse. Although Screening is an economical way to identify drug use in most samples, any positive findings need confirmation to be valid for court proceedings. Samples returning a presumptive positive in Screening necessitate further validation.

Should a sample indicate a presumptive positive in the Screening phase, additional hair is extracted from the original specimen and prepared for Extraction. Here, drugs are extracted from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), which is why hair drug testing remains the most challenging method to execute.

Confirmation of any positive Screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as necessary. The complete laboratory process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can determine drug use up to 90 days, whereas urine tests have a more limited detection period.
• High resistance to tampering: Cheating a hair drug test is exceedingly challenging, ensuring more accurate outcomes.
• Historical usage data: It reveals a pattern of drug usage over time, not only recent usage.

Limitations:

• Inability to detect recent usage: A period of about 5-7 days is required for drugs to be detectable in hair.
• Cost considerations: Hair drug tests come with a higher cost compared to other drug testing methods.
• Result variability: Factors like hair color and individual differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Though colloquially termed "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.
