Accredited Drug Testing provides extensive hair follicle drug testing in Randolph, Missouri. For those in need of a hair drug or alcohol assessment, our specialization in hair tests, coupled with our national network of testing centers, ensures availability. Typically, 1.5 to 2 inches of hair from the crown or body can be used. Tests can be customized for drugs, alcohol/ETG, or other specific needs.
In recent times, drug testing methods have increasingly included hair follicle testing. More employers, legal systems, and substance abuse experts opt for hair tests over traditional urine tests. These tests are favored by zero-tolerance employers, judicial systems, and probation services. Hair testing provides a prolonged detection window for drug use, lasting up to 90 days, collected under observation, making it highly reliable and resistant to manipulation. Nonetheless, urine tests maintain superiority for detecting recent drug use within five days.

Hair testing has emerged as a robust approach to identify drug and alcohol usage. Hair captures a prolonged record of alcohol and other substances by embedding biomarkers within the fibers of the hair shaft as it grows. If gathered near the scalp, hair can offer nearly a three-month detection interval for identifying alcohol and drug use. Hair collection is straightforward, relatively resistant to tampering, and convenient to transport.
A sample size of 1.5 inches from approximately 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100 mg of hair, which is the optimal amount for screening and verification. For EtG, additional substances, or tests exceeding 10 panels, a quantity of 150 mg is advised. It is preferable to weigh the hair sample on a jeweler's scale. If scalp hair is not present, a similar quantity of body hair can be used. "Head hair" pertains exclusively to scalp hair, while "body hair" encompasses all other hair types (such as facial and axillary).
Process Overview
The laboratory analysis of a drug test result encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary processing of a sample within a laboratory's framework. This phase involves ensuring that the sample is properly sealed and delivered, allotting a random LAN (Laboratory Accessioning Number), and finalizing any extra data input absent from an electronic chain of custody protocol.
Screening preliminarily evaluates the sample for drugs of abuse. While it is an economical method to exclude drug usage in a majority of samples, any positive results in Screening must be confirmed for legal admissibility. Samples showing presumptive positivity during Screening require subsequent confirmation.
For samples testing presumptively positive during the Screening phase, additional hair is extracted from the original sample and readied for Extraction. Here, substances are extracted from hair at much lower concentrations than with alternative techniques (such as urine or oral fluid), highlighting the complexity of hair drug screening as a methodology.
To confirm any positive screening outcomes, methods like GC/MS, GC/MS/MS, or LC/MS/MS are utilized. Any presumptively positive samples undergo a washing stage prior to confirmation if necessary. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair classification and in alignment with the ISO / IEC 17025 accreditation norms.

Note: Although commonly termed "hair follicle tests," the examination actually analyzes the hair strand and not the follicle embedded beneath the scalp.
