Hair Follicle Drug Testing - Bloomington, MD

What it is, How it works

Hair analysis is now widely regarded as an effective method for identifying drug and alcohol intake. Hair strands retain long-term data on alcohol and drug use by embedding biomarkers within the fibers as the hair grows. If taken near the scalp, hair can offer a detection period of up to nearly 3 months for substances. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A strand measuring 1.5 inches with about 200 hairs (comparable to a #2 pencil's thickness) closest to the scalp provides 100mg of hair, the optimal amount needed for both initial and confirmatory assessments. For tests including EtG, additional panels, or over 10 panels, a specimen of 150mg is advised. Utilizing a jeweler’s scale for weighing is suggested. Should scalp hair not be accessible, an equivalent volume of body hair can be used. It's important to note that head hair specifically implies scalp hair, whereas body hair encompasses all other types (such as facial and axillary).

Process Overview

The complete process of laboratory drug testing encompasses Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the preliminary handling of a sample within the laboratory's framework. This step includes confirming secure sealing and correct shipping, assigning a unique LAN (Laboratory Accessioning Number), and supplementing any missing data not covered through an electronic chain of custody.

Screening includes an initial procedure to quickly detect drug abuse. Though it's an economical way to eliminate drug use for many samples, a confirmation is necessary for a positive result to be court-acceptable. Any samples that appear positive during Screening require a validating secondary test.

During the Screening phase, if a sample appears positive, additional hair from the specimen is prepared for Extraction. This phase involves isolating drugs from hair at much lower concentrations compared to other methods (such as urine or oral fluid), which makes hair drug testing a more complex method to conduct.

Confirming a positive result is carried out with GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples undergo washing before confirmation when necessary. The lab process from start to finish, Accessioning through Confirmation, is assessed under the CAP (College of American Pathologists) Hair standards and the accreditation of ISO / IEC 17025.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can reveal drug use up to 90 days, in contrast to urine testing with a shorter detection span.
• Challenging to falsify: Manipulating a hair drug test is very challenging, thus the results are more dependable.
• Reveals historical usage: Hair testing provides a record of drug consumption over time, not merely recent use.

Limitations:

• Can't detect recent usage: Drugs take around 5-7 days to become detectable in hair.
• Expense: Hair drug testing tends to be pricier than other methods.
• Results can vary: Hair color and individual differences in growth can influence drug metabolite levels in hair.

Note: Despite often being termed "hair follicle tests," the analysis actually focuses on the hair strands above the scalp rather than the follicles.
