Hair tests are now recognized as an effective means for identifying drug and alcohol consumption. Hair retains biomarkers in the strands, offering a prolonged record of substance use. When collected near the scalp, hair can reveal drug and alcohol use for up to around 90 days. Hair collection is straightforward, tampering is challenging, and shipping is uncomplicated.
A sample measuring 1.5 inches with approximately 200 hair strands (roughly the diameter of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the optimal sample for analysis and verification. For EtG, additional tests, or tests beyond 10 panels, a specimen of 150mg is preferable. Using a jeweler’s scale for specimen weighing is suggested. If scalp hair cannot be obtained, an equivalent quantity of body hair might be used. Here, "head hair" refers specifically to scalp hair, whereas "body hair" comprises all other hair forms (facial, axillary, etc.).
Process Overview
The primary stages in laboratory processing of drug test outcomes include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary integration of a sample into the lab's system. This step ensures proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and fulfills any data entry absent from the electronic custody chain.
Screening is a cursory evaluation for drugs. Although a cost-efficient method to negate drug usage in most samples, a positive screen must be verified to be legally validated. Samples showing presumptive positives in Screening mandate a further confirmation.
Should a sample indicate presumptive positive during Screening, additional hair is taken from the initial specimen for Extraction. Drugs are extracted from hair at a much lower concentration in this phase compared to other methods (like urine or oral fluid), making hair drug screening one of the most complex methodologies.
Confirmation of a positive screening outcome is done through GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positives are washed before confirmation, as needed. The full lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair accreditation and ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Though commonly termed "hair follicle tests", the analysis pertains to the hair strand and not the follicle beneath the scalp.
In Elk Creek, CA, hair follicle testing trumps traditional urine tests due to its superior detection accuracy. Unlike urine tests, which have a shorter detection window, hair analyses can identify drug use over an extended period. This advantage ensures a more comprehensive understanding of an individual's substance history, providing employers and legal professionals with a dependable assessment method.
Moreover, the observed collection process in hair testing minimizes the chances of sample tampering, which is a known issue with urine tests. With this secure method, results are trusted and credible.
One of the standout features of hair follicle testing in Elk Creek, CA is its extended detection window. Unlike urine tests, hair follicle assessments can uncover drug use over a 90-day period. This prolonged detection offers employers a broad perspective of an employee's or candidate's substance use history, crucial for making informed hiring or disciplinary decisions.
Such extensive detection ensures that employers gain a clear picture of behavioral patterns, thus supporting a drug-free workplace. This long window helps protect against recent detoxification efforts used to pass shorter-term tests.
Hair follicle drug tests in Elk Creek, CA provide a tamper-resistant testing solution. The hair analysis process significantly diminishes any attempt at adulterating the sample, leading to foolproof results. This tamper-proof nature ensures that the results are reliable, maintaining the integrity of the assessment for employers and legal entities relying on accurate data.
