Accredited Drug Testing ensures comprehensive hair follicle drug evaluations in Killen, Alabama. When in need of a hair drug or alcohol exam, Accredited Drug Testing excels in hair assessments, hosting numerous testing sites across the nation, perfect for this purpose. Typically, a person should have 1.5 to 2 inches of hair on the head or body to facilitate testing. These hair assessments can screen for drugs, alcohol/ETG, or other tailored options.
Recently, hair follicle evaluations have become more commonplace in drug testing protocols. A plethora of employers, judicial systems, and substance abuse experts now prefer hair tests over traditional urine evaluations. Such tests are favored by zero-tolerance employers, courts, and probationary individuals. The principal advantage of a hair assessment is a significantly longer detection window, usually up to 90 days, with an observed collection process, making them hard to falsify. Nonetheless, for activities within the past five days, urine tests remain the most precise.

Hair testing is acknowledged as an effective means of detecting drug and alcohol usage. Hair holds a chronicle of alcohol and drugs by encapsulating biomarkers within the growing hair fibers. When hair is obtained near the scalp, it offers up to around a 3-month detection period for alcohol and drugs. The collection of hair is straightforward, relatively hard to tamper with, and simple to send.
A 1.5-inch piece consisting of about 200 hair strands (about the dimension of a #2 pencil) nearest the scalp will yield 100mg of hair, deemed the optimal sample for both screening and confirmation. For EtG, add-ons, and/or tests beyond 10 panels, 150mg of the specimen is advisable. Utilizing a jeweler's scale for weighing the specimen is suggested. If scalp hair isn’t available, an equivalent quantity of body hair may be used. When indicating head hair, it pertains solely to scalp hair. Body hair signifies all other hair categories (facial, axillary, etc.).
Process Overview
The lab processing for a drug test outcome encompasses Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial processing phase where a sample is integrated into a lab’s system. This includes confirming that the sample was properly sealed and delivered, allocating an arbitrary LAN (Laboratory Accessioning Number), and completing any extra data entry not available via an electronic chain of custody system.
Screening represents an initial swift test for drugs of abuse. Though a cost-efficient manner to rule out drug use in the majority of samples, any positive screen requires confirmation to be valid in court. Samples that are positively detected in Screening necessitate secondary confirmation.
Should a sample reflect positive results in the Screening phase, additional hair is extracted from the original specimen for Extraction. In this stage, drug extraction from hair is done at significantly lower concentrations than with other techniques (e.g., urine or oral fluid), making hair drug analysis the most challenging technique to execute.
Confirmation of any positive screening result is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with a presumptive positive are cleansed before confirmation if necessary. The entire lab process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation standards of ISO / IEC 17025.

Note: While commonly termed "hair follicle tests", the test evaluates the hair strand, not the hair follicle beneath the scalp.
