In Mercedes, Texas, Accredited Drug Testing facilitates comprehensive hair follicle drug testing. If you're seeking a hair-related drug or alcohol evaluation, we specialize in hair assessments and offer testing facilities in every city Nationwide equipped to conduct such tests. For most instances, a hair length of 1.5 to 2 inches from the head or body can be used. These tests are capable of detecting drugs, alcohol/ETG, and other tailored hair analysis options.
Recently, the use of hair follicle tests in drug testing has become increasingly prevalent. A number of employers, legal entities, and Substance Abuse specialists are opting for hair tests over traditional urine screenings. Employers with strict no-drug policies, as well as courts and individuals on probation, frequently utilize hair follicle tests. A significant advantage of these tests is their extended detection window for substances, generally up to 90 days, obtained via a monitored collection that is virtually impossible to tamper with. Nonetheless, for recent drug use within 5 days, urine tests remain the most accurate.

Hair testing is regarded as an effective method for detecting drug and alcohol use. It provides a long-term record of these substances by capturing biomarkers within the fibers of the growing hair strand. When collected near the scalp, hair can offer a detection window of up to about three months for alcohol and other drugs. It's easy to gather, difficult to tamper with, and simple to transport.
A 1.5-inch segment of roughly 200 hair strands (about the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the preferred amount for screening and confirmation tests. For EtG, additional analyses, and/or tests exceeding 10 panels, 150mg is advised. We recommend using a jeweler’s scale to weigh the sample. If scalp hair isn’t available, an equivalent amount of body hair can be collected. When mentioning head hair, it pertains specifically to scalp hair. Body hair refers to all other types (facial, axillary, etc.).
Process Overview
There are four primary stages in the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial processing of a sample into a lab’s system. This step involves confirming the sample was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing additional data entry not provided by an electronic chain of custody system.
Screening involves a preliminary rapid check for drugs of abuse. While it’s an economical means to discount drug use for most samples, any positive screen has to be confirmed to be admissible in a legal setting. Samples that show presumptive positivity in Screening need a follow-up confirmation.
If a sample is presumptively positive during Screening, more hair is retrieved from the inaugural specimen and prepped for Extraction. During this step, drugs are extracted from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), which is why hair drug screening is the most intricate method to execute.
Confirmation of any positive screening results is done using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, all presumptively positive samples undergo a necessary washing. The complete laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly termed "hair follicle tests", the examination actually assesses the hair strand, not the follicle beneath the scalp.
In Mercedes, TX, hair follicle testing offers significant advantages over traditional urine tests. Unlike urine tests, hair testing provides a superior detection accuracy, offering a comprehensive view of an individual's drug consumption history.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.
It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
