Accredited Drug Testing offers comprehensive hair follicle drug testing services in Keswick, California. When you need a hair drug or alcohol test, Accredited Drug Testing excels in this area, with facilities nationwide ready to administer these tests. Typically, 1.5 to 2 inches of hair from the scalp or body can be utilized. Hair tests can screen for drugs, alcohol/ETG, or other personalized testing options.
Over the years, the preference for drug testing methods has increasingly leaned towards hair follicle testing. This method is being favored by employers, judiciary systems, and substance abuse experts over traditional urine tests. Hair follicle tests serve best for employers with strict drug policies, judicial requirements, and probation contexts. A notable advantage of hair tests is their extended detection period, covering up to 90 days, while being meticulously collected, ensuring minimal risk of result tampering. However, urine tests still maintain higher accuracy for detecting recent drug use within a 5-day window.

Hair analysis is widely recognized as a significant tool for identifying substance use. Hair captures a historical record of alcohol and drug usage by embedding markers within its growing fibers. If gathered near the scalp, hair may offer approximately a 3-month detection timeline for substances. Hair collection is straightforward, challenging to tamper with, and easy to transport.
A hair sample of 1.5 inches, equivalent to about 200 strands (the width of a #2 pencil) closest to the scalp, yields 100mg, which is the preferred amount for evaluation and verification. For enhanced assessments like EtG or those surpassing 10 panels, 150mg is advisable. We suggest using a jeweler's scale for measuring the sample. If scalp hair isn't present, a comparable quantity of body hair is acceptable. "Head hair" exclusively indicates scalp hair, while "body hair" encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
There are four principal stages in laboratory drug test processing: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary integration of a sample into a laboratory's system. This process ensures the sample's appropriate sealing and transport, allocates a random LAN (Laboratory Accessioning Number), and finalizes any supplementary paperwork absent in an electronic custody system.
Screening offers a preliminary drug abuse check. Although Screening effectively dismisses drug consumption in most samples, a positive result requires confirmation to be legally valid. Samples showing presumptive positivity in Screening necessitate further confirmation.
When a sample tests positive in Screening, additional hair is extracted from the specimen for Extraction, where drugs are removed at concentrations far lower than those detected in urine or oral fluid, illustrating the complexity of hair drug analysis.
Confirmation of positive Screening outcomes is done using GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive is cleansed before confirmation if needed. The complete laboratory procedure, from Accessioning to Confirmation, is scrutinized within both the CAP (College of American Pathologists) Hair classification and accredited to ISO / IEC 17025 standards.

Note: Although often termed "hair follicle tests," this procedure involves analyzing the hair strand, not the follicle beneath the scalp.
