Accredited Drug Testing offers comprehensive hair follicle drug testing services in Middleburg, Virginia. If you need to administer a hair drug or alcohol test, Accredited Drug Testing has expertise in hair testing and testing centers nationwide that can conduct the test. Typically, 1.5 to 2 inches of hair from the crown of the head or body may be used. Hair tests can detect drugs, alcohol/ETG, or support other specialized hair testing needs.
Recently, hair follicle drug tests have become more prevalent in drug testing practices. Many employers, courts, and substance abuse professionals now require hair drug tests over standard urine tests. Employers with zero-tolerance drug policies, courts, and probationary individuals benefit from hair tests. The key advantage of these tests is their extended drug use detection period of up to 90 days, conducted through observed collection, making them difficult to manipulate. However, urine tests remain the best option for detecting drug use within the last 5 days.

Hair testing has gained recognition as a robust method for identifying drug and alcohol consumption. Hair strands capture biomarkers indicating drug and alcohol use, providing a long-term record by embedding these markers within the strands as they grow. When samples are taken near the scalp, hair can deliver a detection window for drugs and alcohol spanning up to three months. Collecting hair is straightforward, it is not easy to tamper with, and it is simple to send off for analysis.
A 1.5-inch segment consisting of roughly 200 hair strands (similar in thickness to a #2 pencil) near the scalp provides 100mg of hair, which is the preferred sample size for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is advised. It is recommended to measure the specimen using a jeweler’s scale. In instances where scalp hair cannot be obtained, an equivalent portion of body hair can be used. References to head hair specifically indicate scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
Laboratory processing of a drug test result encompasses four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial integration of a sample into a laboratory’s workflow. This phase ensures that the sample was sealed and shipped correctly, a random LAN (Laboratory Accessioning Number) is assigned, and any further data entry not captured by an electronic chain of custody system is completed.
Screening serves as an initial rapid assessment for drug abuse. Although Screening economically aids in ruling out drug use for most samples, positive screenings require confirmation to be legally viable. Any samples testing presumptively positive in Screening necessitate a subsequent confirmation step.
Should a sample test presumptively positive during the Screening phase, additional hair is extracted from the original sample for the Extraction phase. During Extraction, substances are isolated from hair at significantly lower concentrations than those in urine or oral fluid methodologies, rendering hair drug screening particularly challenging to perform.
Confirmation of positive screening results involves techniques such as GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples undergo necessary washing before confirmation. The complete laboratory process, from Accessioning through Confirmation, complies with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although often termed as "hair follicle tests", the analysis is conducted on the hair strand, not on the follicle beneath the scalp.
