Urine| Hair Follicle | Oral Fluid | Blood | ETG
Hair analysis has evolved into a robust method for identifying the consumption of drugs and alcohol. Hair fibers retain a prolonged history of drug and alcohol presence by embedding biomarkers within the strands as they grow. When obtained near the scalp, hair can offer a detection timeframe extending nearly up to three months for substances. The collection process for hair is straightforward, relatively tamper-resistant, and convenient to transport.
A sample of 1.5 inches comprising roughly 200 hair strands (comparable to the size of a #2 pencil) closest to the scalp provides 100mg of hair, an optimal quantity for both initial testing and subsequent verification. For EtG, certain additional tests, or panels exceeding ten, a collection of 150mg is advised. Utilizing a jeweler’s scale for precise measurement of the specimen is advisable. In instances where scalp hair is absent, a corresponding amount of body hair may be gathered. The term head hair specifically pertains to scalp hair, whereas body hair denotes any other types (e.g., facial, axillary).
Process Overview
The laboratory procedure for analyzing a drug test result encompasses four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves incorporating a sample into the laboratory system initially. This procedure includes confirming proper sealing and shipment of the sample, generating a random LAN (Laboratory Accessioning Number), and completing any supplemental data input absent from an electronic chain of custody.
Screening involves a preliminary swift evaluation for drugs of abuse. Though Screening offers an economical method to dismiss drug use in the majority of cases, a positive result warrants confirmation to hold up in court. Samples that appear positively during Screening necessitate a subsequent confirmation step.
If a sample is assumed positive during the Screening phase, additional strands are extracted from the original specimen and readied for Extraction. During this phase, drugs are isolated from hair at significantly reduced concentrations compared to alternative methodologies (such as urine or oral fluid), thereby making hair drug analysis the most challenging methodology to conduct.
Confirmation of any affirmative Screening outcome is carried out utilizing GC/MS, GC/MS/MS, or LC/MS/MS. All samples yielding presumptive positive results undergo a washing process prior to confirmation as required. The entire laboratory procedure, from Accessioning to Confirmation, is conducted under the scrutiny of both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 criteria.
Advantages of hair drug testing:
Limitations:
Note: Commonly termed "hair follicle tests," the analysis is performed on the hair strand itself, not the follicle beneath the scalp.
