Accredited Drug Testing provides comprehensive hair follicle drug screening in St. Thomas, Missouri. For those requiring a hair drug or alcohol assessment, Accredited Drug Testing excels in hair analysis, with facilities available in every city across the nation to conduct hair screenings. Typically, 1.5 to 2 inches of hair from the head or body are utilized. Hair analysis can check for drugs, alcohol/ETG, or other tailored testing options.
In recent years, drug screening methods have increasingly included hair follicle drug tests. Many employers, courts, and substance abuse experts now prefer hair drug tests over conventional urine tests. Hair follicle drug screenings are favored by employers enforcing strict no-drug policies, courts, and individuals on probation. The key advantage of such a test is its extended detection period, often up to 90 days, with sampling done under observation, making it nearly impossible to tamper with. However, for detecting use within the past 5 days, urine tests remain more precise.

Hair assessment is now recognized as an effective method for identifying drug and alcohol consumption. Hair retains a long-term record of alcohol and drug exposure by embedding biomarkers within the fibers of the developing hair strand. When retrieved near the scalp, hair can offer up to a roughly 3-month detection timeframe for alcohol and drugs. Hair is straightforward to gather, relatively challenging to tamper with, and convenient to transport.
A 1.5-inch segment of about 200 hair strands (similar to the thickness of a #2 pencil) nearest the scalp results in 100mg of hair, the optimal sample for testing and validation. For EtG, additional tests, and/or analyses above 10 panels, 150mg of the sample is advisable. It is suggested to measure the sample using a jeweler’s scale. If head hair is not present, an equivalent quantity of body hair may be collected. When referencing head hair, it pertains solely to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The key stages in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the initial handling of a sample within a lab’s framework. This encompasses confirming that the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data input absent from an electronic chain of custody system.
Screening entails an initial rapid evaluation for substances of abuse. While Screening is a cost-efficient method to dismiss drug usage in most samples, any positive screen must be verified to be legally acceptable. Samples that appear positive in Screening demand a secondary validation.
If a sample appears positive in the Screening phase, extra hair is extracted from the initial sample and prepared for Extraction. At this stage, drugs are isolated from hair at a much reduced concentration than in other techniques (e.g., urine or oral fluid), explaining why hair drug analysis is the most complex technique to execute.
Validation of a positive screening outcome is performed using GC/MS, GC/MS/MS or LC/MS/MS. All samples that appear positive are cleaned before confirmation as necessary. The complete lab procedure from Accessioning to Confirmation is examined according to both the CAP (College of American Pathologists) Hair criteria and compliance with ISO / IEC 17025 standards.

Note: Although commonly termed as "hair follicle tests," the analysis actually examines the hair strand rather than the follicle under the scalp.
