Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair can capture a long-term record of substance use by storing biomarkers within the strands as the hair grows. When a sample is cut near the scalp, it can provide up to a three-month detection range for substances. The collection process is straightforward, the samples are hard to tamper with, and they are easy to transport.
A sample measuring 1.5 inches, consisting of roughly 200 hair strands (around the thickness of a #2 pencil), cut closest to the scalp, yields 100mg of hair—the optimal amount for both initial analysis and confirmation. For tests including EtG, additional analytes, or those exceeding ten panels, 150mg of hair is advisable. We suggest using a jeweler’s scale for accurate weighing. In cases where scalp hair is unavailable, an equivalent amount of body hair can be used. When mentioning head hair, we specifically refer to scalp hair. Body hair includes all other types, such as facial or axillary hair.
Process Overview
The drug test result processing in a laboratory includes four critical stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the introduction of a sample into the laboratory's system. This step ensures the sample's proper sealing and transit and assigns a unique LAN (Laboratory Accessioning Number), while also completing any missing data not captured by an electronic chain of custody.
During Screening, a preliminary investigation for drug use is conducted. Although Screening offers an economical way to exclude drug use in most cases, any positive results obtained must be verified to be legally valid. Samples that test presumptively positive in this stage require further confirmation.
Positive results from Screening involve pulling additional hair from the original sample and preparing it for Extraction. In this phase, substances are isolated from the hair, though at a lower density than found in other testing methods, like urine or oral fluid, making hair drug testing particularly challenging.
Confirmation of positive Screening results is done through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positives undergo washing before confirmation if necessary. The entire process, from Accessioning to Confirmation, is conducted under scrutiny following both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 standards.
