Hair testing is increasingly recognized as an effective method for detecting substance use, including drugs and alcohol. By capturing biomarkers within the strands, hair offers a comprehensive history of alcohol and drug consumption over time. When cut close to the scalp, hair can reveal substance use within an approximate 90-day window. The collection process is straightforward, the sample is hard to tamper with, and it is easily transportable.
A hair sample that is 1.5 inches long with roughly 200 strands (comparable to the thickness of a #2 pencil) closest to the scalp will yield about 100mg, which is considered optimal for both initial screening and further verification. If testing for EtG or multiple panels beyond ten, a larger sample of 150mg is advised. We suggest utilizing a jeweler’s scale for accurate measurement. In cases where scalp hair is absent, a comparable amount of body hair can be utilized. When mentioning head hair, it refers strictly to scalp hair, while body hair encompasses all other hair types (such as facial or axillary).
Process Overview
There are four pivotal steps in processing drug test results in the laboratory: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves incorporating a sample into the lab’s system, ensuring it was sealed and parceled correctly, assigning it a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry that is not available through an electronic chain of custody.
Screening consists of an initial evaluation for substances. Though it's an economical means to dismiss drug presence in most cases, a positive result in the Screening phase calls for further verification for legal validity. Presumptive positives identified during Screening require additional confirmation.
Should a sample yield a presumptive positive in Screening, further segments are taken from the original hair sample for Extraction. In this step, drugs are extracted at lower concentrations than those found with other testing methods like urine or oral fluids, making hair testing quite challenging.
Confirmed positive cases from Screening proceed to Confirmation via methods such as GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, presumptive samples undergo a cleansing stage as required. From Accessioning to Confirmation, the entire testing protocol adheres to the standards of both the CAP (College of American Pathologists) Hair certification and ISO / IEC 17025.
