The use of hair testing has evolved into a highly effective method for detecting drug and alcohol use. By capturing biomarkers within the strands, hair retains a comprehensive timeline of substance use. When samples are taken close to the scalp, hair can reveal drug and alcohol exposure for an estimated three months. Collection is straightforward, relatively resistant to tampering, and convenient for shipping.
A hair sample measuring 1.5 inches and comprising 200 strands (approximately the width of a #2 pencil) near the scalp yields 100mg, which is the optimal amount for both screening and confirmation. For tests involving EtG, add-ons, or more than 10 panels, it's advisable to collect 150mg. We suggest using a jeweler's scale for weighing samples. If scalp hair isn't available, an equivalent quantity of body hair can be used. "Head hair" refers specifically to scalp hair, while "body hair" includes all other types (such as facial, axillary, etc.).
Process Overview
The key stages in processing a drug test result in the laboratory are Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial phase of introducing a sample into the lab system. This step ensures the sample is properly sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and completes any necessary data entry not covered by an electronic chain of custody.
Screening provides a swift assessment for substances of abuse. Although it's an economical way to eliminate drug use in most cases, a positive screen necessitates confirmation for legal validity. Samples deemed presumptively positive in Screening need further validation.
When a sample tests presumptively positive during Screening, additional hair is extracted from the specimen for further processing. This stage isolates substances from hair at much lower concentrations than other methods (like urine or oral specimens), making hair drug testing particularly challenging.
Confirmation of any positive screen involves techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing if necessary before confirmation. This entire process, from Accessioning to Confirmation, is conducted under the guidelines of both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation.
