For comprehensive hair follicle drug testing services in Charlotte, Tennessee, turn to Accredited Drug Testing. Whether you're seeking a hair drug test or alcohol screening, our expertise center around hair testing. With testing facilities in every city across the nation, our centers are equipped to handle your needs. To conduct a test, 1.5 to 2 inches of head or body hair is typically required. Options include detecting drugs, alcohol/ETG, and other specific hair testing configurations.
Recently, drug testing methods have increasingly favored hair follicle tests. This change impacts employers, legal bodies, and Substance Abuse specialists, who now often opt for these tests over standard urinalysis. Hair follicle tests are preferred by entities with zero-tolerance policies, courts, and for individuals on probation. The major advantage of these tests is their extended detection window, up to 90 days, with observation during the sample collection, which makes them extremely challenging to tamper with. However, urinalysis remains the most accurate for detecting very recent drug use within the past five days.

Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. With hair, one can obtain an extended timeline of substance use by encapsulating biomarkers within the hair's structure as it grows. When hair is collected near the scalp, it can offer a detection period of up to around three months for substances. The process of collecting hair is straightforward, hard to tamper with, and convenient for shipment.
A 1.5-inch segment comprising roughly 200 hairs (comparable in thickness to a #2 pencil) nearest to the scalp yields 100mg, which is the optimal sample size for both initial screening and confirmation. For tests such as EtG or those exceeding ten panels, it's advisable to use 150mg. Utilizing a jeweler’s scale for weighing the sample is suggested. In scenarios where scalp hair isn't available, a similar quantity of body hair can be utilized. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other hair, including facial and axillary.
Process Overview
The core stages in the lab processing of a drug test consist of Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially integrated into a lab’s system. This step involves ensuring the sample's seal and proper shipment, allocating a random LAN (Laboratory Accessioning Number), and completing any additional data required if not provided via an electronic chain of custody system.
Screening acts as a preliminary assessment for substances of abuse. While it is a cost-efficient approach to exclude drug use in most cases, a positive screen must be confirmed to be valid in legal proceedings. Any samples deemed to be positive in Screening need further confirmation.
Should a sample test positive during Screening, additional hair is taken from the primary specimen for Extraction. In this phase, drugs are separated from hair exhibiting a much lower concentration compared to alternative methods (e.g., urine or oral fluid), which is why hair drug screening is acknowledged as the most challenging method to execute.
GC/MS, GC/MS/MS, or LC/MS/MS are utilized for confirming any positive screening outcomes. Presumptive positive samples are cleaned prior to confirmation as necessary. From Accessioning to Confirmation, the full laboratory procedure is scrutinized under the CAP (College of American Pathologists) Hair designation and compliant with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Though commonly termed "hair follicle tests," the analysis targets the hair shaft, not the follicle beneath the scalp.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. 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. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation. 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.
