Accredited Drug Testing offers full-service hair follicle drug testing in Belvedere, CA. For those needing a drug or alcohol hair test, our specialized centers provide hair testing across all major cities nationwide with proficiency in conducting hair tests. Generally, 1.5 to 2 inches of hair from the scalp or body can be used. Hair testing can detect drugs, alcohol/ETG, or be tailored for other specific hair analysis.
Nowadays, hair follicle drug testing has become more prevalent in drug screening methods. Employers, legal courts, and substance abuse professionals now frequently opt for hair drug tests over traditional urine tests. Organizations with zero-tolerance policies, legal systems, and probation services rely on hair follicle screenings, which offer a longer detection window of up to 90 days, conducted under supervision to minimize tampering risks. However, for recent usage within 5 days, urine tests remain more effective.
* You must register by phone or online to receive your donor pass/registration prior to proceeding to the testing center. You must bring a valid government issued ID along with the registration/barcode number which was sent to you by email.

Hair analysis is now regarded as a potent method for identifying drug and alcohol consumption. Hair offers an extended timeline by capturing markers in the strands of growing hair. Collected near the scalp, hair can reveal alcohol and drug presence for up to roughly 3 months. It's straightforward to collect, somewhat resistant to tampering, and easy to transport.
A sample measuring 1.5 inches of roughly 200 hair strands (comparable to a #2 pencil) near the scalp provides 100mg, which is ideal for evaluation and validation. For EtG, additional tests, and/or those exceeding 10 panels, a specimen of 150mg is advised. We advise using a jeweler’s scale for weighing the sample. If scalp hair isn't available, an equivalent amount of body hair can be used. In discussing head hair, we mean scalp hair only, while body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The lab processing of drug test results involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial integration of a sample into a lab's system. This covers confirming the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing additional data entry not covered by an electronic chain of custody.
Screening offers a preliminary check for drug abuse. Screening is a low-cost method to eliminate drug usage in most samples, but a positive screen requires confirmation for court validity. Samples that test potentially positive in Screening need a further confirmation.
If Screening indicates a presumptive positive, more hair is extracted from the initial sample for Extraction. In this phase, drugs are isolated from hair at a significantly lower concentration than other methods (like urine or oral fluid), making hair drug testing the most challenging method to perform.
Confirmation of positive screening outcomes is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation as necessary. The entire lab sequence from Accessioning to Confirmation is verified under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
