Hair Follicle Drug Testing - Comus, MD

What it is, How it works

Hair evaluations are now recognized as an efficient mechanism for identifying drug and alcohol consumption. Hair retains a long-standing history of alcohol and drug use by capturing biomarkers within the fibers of a growing hair strand. When acquired near the scalp, hair can reveal up to a 90-day detection range for alcohol and drugs. Hair collection is easy, challenging to tamper with, and convenient to transport.

Collecting a 1.5-inch section of roughly 200 hair strands near the scalp, similar in thickness to a #2 pencil, yields 100mg of hair, which is optimal for analysis and confirmation. For EtG tests, add-ons, or tests exceeding 10 panels, 150mg of the sample is advised. Using a jeweler’s scale is recommended for specimen weighing. If scalp hair is absent, an equivalent amount of body hair can be gathered. Reference to head hair pertains only to scalp hair, while body hair refers to other hair types (facial, axillary, etc.).

Process Overview

The comprehensive stages of lab processing for a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial input of a sample into a lab's system. It confirms that the sample was sealed and transported accurately, designates a random LAN (Laboratory Accessioning Number), and finalizes any additional data entry missed by an electronic chain of custody framework.

Screening is a preliminary inspection for drugs of abuse. It is a cost-effective strategy to dismiss drug consumption in most samples; however, a positive screen demands confirmation to hold up in legal scenarios. Samples testing presumptively positive during Screening do require further verification.

If a sample is found presumptively positive in the Screening stage, additional hair is extracted from the initial sample for Extraction. At this point, drugs are isolated from hair at a significantly lower concentration than other methodologies (e.g., urine or oral fluid), making hair drug screening the most demanding methodology to execute.

Confirmation of any positive screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed prior to confirmation as required. The complete lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection range: Hair drug tests can trace drug consumption for up to 90 days, whereas urine tests have a shorter monitoring period.
• Cheating deterrent: Hair drug tests are very hard to deceive, yielding more reliable results.
• Displays historical behavior: It reveals a pattern of drug consumption over time, not just recent use.

Limitations:

• Incapable of detecting recent consumption: Detection in hair requires about 5-7 days post-consumption.
• Expense: Hair drug tests are generally pricier compared to other methods.
• Result variations: Factors like hair color and individual differences in hair growth may impact drug metabolite concentration in hair.

Note: Often called "hair follicle tests", these tests actually evaluate the hair strand, not the follicle underneath the scalp.
