Hair testing is recognized as an effective means for uncovering drug and alcohol consumption. Hair furnishes a prolonged history of substance use by embedding biomarkers within the fibers of the developing hair strand. When samples are taken near the scalp, hair can offer a detection window of up to roughly 3 months for alcohol and other substances. Collecting hair is straightforward, challenging to tamper with, and easy to send.
A sample measuring 1.5 inches, comprising about 200 hair strands (approximately the thickness of a #2 pencil) nearest the scalp, will yield 100mg of hair, which is the optimal amount for testing and validation. For tests such as EtG, additional analyses, and/or panels exceeding 10, 150mg of the sample is advised. We suggest using a jeweler's scale for measuring the sample. If scalp hair isn't accessible, a similar quantity of body hair might be taken. "Head hair" specifically implies scalp hair. "Body hair" pertains to all other types of hair (including facial, axillary, etc.).
Process Overview
The laboratory procedure for analyzing a drug test result includes four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into the laboratory's apparatus. This step entails confirming that the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry that an electronic chain of custody system didn't provide.
Screening includes a preliminary assessment for abused drugs. Although Screening provides an economical way to exclude drug intake in most samples, a favorable screen must be confirmed for legal proceedings. Any sample presumed positive during Screening mandates additional confirmation.
In the event of a presumptive positive result in Screening, extra hair is taken from the original sample and made ready for Extraction. Here, drugs are isolated from hair at a significantly lower concentration compared to other methodologies (e.g., urine or oral fluid), which makes hair drug testing the most challenging methodology.
Confirmation of any favorable screening outcomes utilizes GC/MS, GC/MS/MS, or LC/MS/MS. Presumed positive samples are washed as necessary prior to confirmation. The complete laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly labeled "hair follicle tests", the assessment evaluates the hair strand rather than the hair follicle beneath the scalp.
