With Accredited Drug Testing, you can access comprehensive hair follicle drug testing services in San Joaquin Hills, California. Whether you're requiring a drug or alcohol test through hair samples, our specialization includes hair testing with numerous locations nationwide ready to assist. Generally, a hair sample of 1.5 to 2 inches from the scalp is necessary, although body hair can also be used in specific instances. Hair analyses cover drugs, alcohol/ETG, or can be customized as needed.
Recently, hair follicle drug tests have become more common in drug testing protocols, replacing standard urine tests. These are favored by employers with zero-tolerance policies, courts, and individuals on probation. One major advantage of hair tests is their longer detection times, typically up to 90 days, with the process performed under observation—a method difficult to circumvent. Nevertheless, for drug use within the past five days, urine tests remain more accurate.

The assessment of substance use through hair analysis is recognized as an efficient method. Hair encapsulates a historical record of substances like drugs and alcohol by embedding biomarkers within the growing fibers. When collected near the scalp, hair reveals a detection window of up to about three months for these substances. Hair collection is straightforward, hard to tamper with, and simple to transport.
A sample measuring 1.5 inches, containing roughly 200 hair strands (akin to the size of a #2 pencil) nearest to the scalp, yields approximately 100mg of hair, the optimal quantity for screening and verification. For tests involving EtG, additions, or panels exceeding 10, a 150mg sample is advised. Using a jeweler’s scale to weigh specimens is recommended. If scalp hair is not present, a similar amount of body hair may be taken. References to head hair imply exclusively scalp hair, while body hair pertains to all other varieties (such as facial or axillary hair).
Process Overview
There are four essential stages in the laboratory processing of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage of integrating a sample into the lab's system, which includes confirming that the sample was correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody system.
Screening serves as an initial rapid evaluation for recreational substances. It is a cost-effective method for dismissing drug use in a majority of samples, but a positive result must undergo confirmation to be valid in legal scenarios. Samples that show presumptive positivity during Screening necessitate further verification.
If Screening finds a sample presumptively positive, additional hair is extracted from the initial sample for Extraction. During this stage, drugs are extracted from hair at a lower concentration than in other methods (like urine or oral fluids), making hair drug screening the most challenging technique.
Confirmation of any positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed prior to confirmation if necessary. The complete laboratory process from Accessioning through Confirmation undergoes review under the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.
