As an efficient method for identifying drug and alcohol consumption, hair analysis is highly regarded. By embedding biomarkers within the growing strand's fibers, hair reflects a prolonged timeline of substance use. When strands are cut near the scalp, they offer nearly a quarter year’s detection period for drugs and alcohol. Hair is straightforward to gather, relatively hard to tamper with, and simple to send.
Gathering a segment that is 1.5 inches, comprising around 200 hair strands akin to a #2 pencil thickness near the scalp, yields 100mg, optimal for screening and confirmation tests. For EtG extensions and tests surpassing ten panels, 150mg is suggested. Use a jeweler’s scale to weigh the sample. If scalp hair is inaccessible, body hair of similar volume can be taken. The term "head hair" solely pertains to scalp hair, whereas "body hair" encompasses all other types (face, armpits, etc.).
Process Overview
The key phases in laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, initial sample integration into a lab's database happens. This phase ensures the sample was appropriately sealed and delivered, associates it with a unique LAN (Laboratory Accessioning Number), and finalizes any extra data recording absent in an electronic custody chain.
Screening performs a preliminary rapid assessment for drug presence. Although cost-effective in excluding drug use in most samples, only confirmed positive screenings are acknowledged legally. Screens indicating possible positivity require confirmatory steps.
If an initial Screening suggests positivity, further hair is extracted from the original sample for Extraction. In Extraction, drugs are retrieved from the hair at significantly diluted levels compared to other methods (e.g., urine or oral fluid), which positions hair drug assessment as a challenging practice.
Confirmation of positive findings follows either GC/MS, GC/MS/MS, or LC/MS/MS protocols. Before Confirmation, every potentially positive sample undergoes washing as required. The entire procedure from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly known as "hair follicle tests", the analysis targets the hair strand, not the follicle beneath the scalp.
Why Choose Hair Follicle Testing?
Compared to urine tests, hair follicle tests offer several advantages in Lynwood Hills, CA. They provide better detection accuracy and are more reliable. Traditional urine tests measure only very recent drug use, which can be manipulated.
Lynwood Hills, CA employers benefit from the extended detection window of hair follicle testing. Drugs sampled from hair can reveal usage from months prior, allowing a thorough investigation into a subject's substance history.
This long detection period is especially beneficial for evaluating candidates' longer-term habits, rather than just recent activities.
Secure and Tamper-Resistant
One standout feature of hair follicle testing in Lynwood Hills, CA, is its robust resistance to tampering. Attempts to alter or substitute samples are rendered almost impossible with the hair collection process. This method ensures that results remain accurate and incontestable.
Our extensive network of testing centers makes drug screening simple for those in Lynwood Hills, CA. Convenient nationwide locations enable quick access to required services without unnecessary travel.
