In Lodi, California, Accredited Drug Testing offers comprehensive hair follicle drug tests. If a hair drug or alcohol test is what you need, our expertise lies in hair testing, and we boast testing centers across the nation, capable of conducting such tests. Typically, 1.5 to 2 inches of hair from the head or body is necessary for the testing process. Hair analysis can detect drugs, alcohol/ETG, or be customized for specific testing needs.
Over the years, the popularity of hair follicle drug tests has risen in the realm of drug testing. Employers, courts, and substance abuse experts are increasingly choosing hair drug tests over traditional urine tests. For institutions with zero-tolerance drug policies, and for individuals on probation, hair tests offer a longer drug detection window, typically up to 90 days. They are collected under observation, making them almost impossible to tamper with. Despite this, urine tests remain the most reliable for identifying drug use within the past five days.

Hair assessment has gained recognition as an effective method for identifying drug and alcohol consumption. Hair offers an extended timeline of substance use by capturing biomarkers in the strands of growing hair. When obtained near the scalp, hair can provide a detection window for substances, including alcohol, of up to roughly 90 days. Hair is easy to collect, challenging to alter, and convenient to ship.
A sample measuring 1.5 inches containing approximately 200 strands of hair (about the diameter of a #2 pencil) nearest to the scalp yields around 100mg, which is the optimal quantity for both initial testing and further validation. For EtG, additional tests, and/or screenings exceeding 10 panels, a 150mg sample is advisable. Utilizing a jeweler’s scale is suggested to weigh the sample. In the absence of scalp hair, an equivalent volume of body hair can be used. Head hair refers specifically to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial incorporation of a sample into a laboratory's system. This step includes verifying the integrity and proper shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional information not accounted for by an electronic chain of custody system.
Screening conducts an initial rapid evaluation for substances of abuse. While it is economical for eliminating drug presence in the majority of samples, a positive screening necessitates confirmation for legal admissibility. Any samples deemed presumptively positive during Screening require a subsequent confirmation.
When a sample shows a presumptive positive during Screening, additional hair is extracted from the original sample for the Extraction process. At this stage, drugs are isolated from the hair at significantly lower concentrations than other testing methods (such as urine or saliva), which makes hair drug screening the most challenging to execute.
Confirmation of positive screening outcomes is undertaken using GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive specimens are cleaned prior to confirmation as needed. The entire lab process, from Accessioning to Confirmation, is scrutinized according to CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.

The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols.

The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.
Clinical Applications of hair testing are witnessed by the insight on environmental tobacco smoke exposure, assessed by hair analysis in a population of students and the study of in utero-exposure to drugs of abuse through neonatal hair analysis. Exposure to drugs was also important in cases of child abuse/neglect, when the clinical purpose of hair testing merge with its forensic applications.
The legal framework surrounding hair testing and the achievement of guidelines to ensure fairness, accuracy, and confidentiality in drug testing practices have also been discussed,and the SoHT consensus on general hair testing and testing for drugs of abuse was presented at the meeting and published as a Letter to the Editor.
