Whether you're seeking a hair drug or alcohol test, Accredited Drug Testing excels in hair assessments, with facilities in every major city nationwide ready to conduct such tests. A hair length of 1.5 to 2 inches on the scalp or body is generally sufficient. Hair tests may evaluate for drugs, alcohol/ETG, or undergo various custom testing selections.
In recent times, hair follicle drug testing has increasingly become a standard practice. Numerous employers, courts, and professionals specializing in Substance Abuse now favor hair testing over conventional urine testing. Hair follicle assessments serve employers with zero-tolerance drug policies, judicial systems, and individuals on probation. A notable advantage of hair follicle drug tests is their extended detection span, typically revealing drug use up to 90 days past, backed by a monitored collection method, thus making cheating nearly unfeasible. Nevertheless, the urine test remains the optimal choice for detecting recent drug use within the past 5 days.

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair offers an extended history of substance use by embedding biomarkers within the strands of hair as they grow. When hair is collected near the scalp, it can reveal a detection window of up to about three months for substances. Hair is straightforward to gather, relatively hard to tamper with, and easy to transport.
A hair sample measuring 1.5 inches with roughly 200 strands (similar in thickness to a #2 pencil) near the scalp yields 100mg, which is an optimal quantity for screening and confirmation purposes. For EtG, additional tests, or those exceeding 10 panels, a 150mg sample is advisable. It's suggested to weigh the specimen using a jeweler’s scale. If scalp hair can't be collected, an equivalent amount of body hair may be used. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other types such as facial and axillary hair.
Process Overview
The primary procedures in the laboratory processing for a drug test include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial handling of a specimen within a lab's system. This consists of ensuring the sample's seal and shipment integrity, issuing a random LAN (Laboratory Accessioning Number), and completing any extra data input absent from an electronic chain of custody system.
Screening consists of a preliminary check for substance abuse. Screening is an economical way to eliminate drug use for most samples, yet positive screenings must be confirmed to hold up in legal situations. Any samples testing presumptively positive during Screening necessitate a secondary confirmation.
Should a sample appear positive during Screening, additional hair is extracted from the original specimen and set for Extraction. During this stage, drugs are drawn from hair at significantly lower levels than other methods (e.g., urine or oral fluid), underscoring why hair drug analysis is among the most challenging to execute.
Confirmation of any positive screen result occurs via GC/MS, GC/MS/MS, or LC/MS/MS. Any samples that are presumptively positive are cleansed before confirmation as required. The complete lab process from Accessioning to Confirmation is checked under the CAP (College of American Pathologists) Hair designation along with ISO / IEC 17025 accreditation standards.

Note: Although frequently termed "hair follicle tests", the analysis actually examines the hair shaft, not the beneath-the-scalp hair follicle.
