Hair testing is widely considered an effective method for identifying drug and alcohol use. Hair captures a historical record of alcohol and drugs by embedding biomarkers within the fibers of the developing hair strand. When clipped near the scalp, this sampling can reveal an approximate three-month detection window for alcohol and substances. Collecting hair is straightforward, challenging to tamper with, and convenient for shipping.
An ideal sample consists of a 1.5-inch section of roughly 200 hair strands (comparable to the size of a #2 pencil) nearest the scalp, which yields 100mg of hair, perfect for screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a sample size of 150mg is advised. We suggest using a jeweler’s scale to weigh the sample. If scalp hair is not available, collecting an equivalent amount of body hair is acceptable. The term "head hair" specifically refers to scalp hair. "Body hair" encompasses all other types, including facial and axillary hair.
Process Overview
The laboratory processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing within the laboratory's system. This step ensures the sample was securely sealed and transported correctly, allocates a random LAN (Laboratory Accessioning Number), and includes any further data entry not available through an electronic chain of custody system.
Screening offers an initial quick assessment for potential drug misuse. Despite being a cost-effective means to exclude drug use in most samples, a positive screening result requires confirmation to hold up in court. Any samples indicating potential positives during Screening must undergo a secondary confirmation.
In instances where the Screening phase suggests a presumed positive, more hair is retrieved from the original specimen for the Extraction process. Here, drugs are extracted from the hair at significantly lower concentrations than found in other testing methods like urine or oral fluids, highlighting hair drug screening as a complex practice.
All positive results from Screening are validated through GC/MS, GC/MS/MS, or LC/MS/MS methods. Prior to confirmation, all samples suspected of a positive result are washed as needed. The entire laboratory process, from Accessioning to Confirmation, is conducted in alignment with both the CAP (College of American Pathologists) Hair designation and the criteria set by ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: While often referred to as "hair follicle tests," the analysis is performed on the hair strand, not the follicle beneath the scalp.
When considering drug testing methods, hair follicle testing in San Saba, TX, provides a clear advantage over traditional urine tests. Why?
