Hair testing is widely recognized as an effective method for identifying drug and alcohol consumption. Hair holds a comprehensive record of alcohol and drugs due to the entrapment of biomarkers within the fiber of the elongating hair strand. When harvested near the scalp, hair can offer a detection window for alcohol and drugs extending up to about 3 months. Hair collection is straightforward, hard to tamper with, and convenient to transport.
A sample measuring 1.5 inches comprising roughly 200 strands of hair (akin to a #2 pencil's girth) closest to the scalp yields 100mg of hair, which is the preferred sample size for both screening and confirmation. For EtG additions and/or tests exceeding 10 panels, a 150mg specimen is suggested. We advise weighing the specimen using a jeweler's scale. Should scalp hair be unavailable, an equivalent volume of body hair may be used. References to head hair specifically denote scalp hair. Body hair includes all other types of hair (facial, axillary, etc.).
Process Overview
The sequence of steps entailed in the laboratory processing of drug test results comprises Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a laboratory's ledger. This process includes verifying the proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), as well as completing any supplementary data entry absent from an electronic chain of custody framework.
Screening involves a preliminary and expeditious assessment for drug abuse indicators. While Screening offers an economical approach to disprove drug use on most samples, a positive result necessitates confirmation for legal validity. Samples showing presumptive positives in Screening require additional confirmation.
If a sample shows a presumptive positive in the Screening phase, additional hair is separated from the original sample and readied for Extraction. During this phase, drugs are drawn out from the hair at a lower concentration compared to other methods (such as urine or oral fluid), making hair drug screening particularly challenging to conduct.
Positive Screening results are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo a cleaning process as required prior to confirmation. The comprehensive laboratory workflow from Accessioning through Confirmation is evaluated in line with both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 standards accreditation.

Limitations:
Note: Although frequently dubbed "hair follicle tests," the examination pertains to the hair strand rather than the scalp-embedded hair follicle.
