Accredited Drug Testing offers comprehensive hair follicle testing services in Colfax, Louisiana. If you're seeking hair-based drug or alcohol tests, Accredited Drug Testing excels in this area, with centers throughout various cities nationwide capable of conducting hair analyses. Typically, 1.5 to 2 inches of hair from the head is needed, or body hair can be used. Hair samples can be checked for drugs, alcohol/ETG, or tailored testing options.
Lately, hair follicle drug testing is increasingly favored for substance testing. Many employers, courts, and Substance Abuse specialists now opt for hair drug tests over traditional urine tests. These tests support zero-tolerance policies, judicial use, and probation monitoring. The key advantage of hair follicle testing is its longer detection period for recent drug use, typically up to 90 days, collected under observation, making it tamper-resistant. However, urine tests are still preferred for detecting drug use in the last 5 days.

Hair testing is increasingly regarded as an effective method for identifying drug and alcohol consumption. Hair can offer a long-term record of alcohol and drug use by encapsulating biomarkers in the strands of the developing hair. A sample taken near the scalp can provide a detection duration of up to three months for alcohol and drugs. Collecting hair is straightforward, difficult to tamper with, and easy to transport.
A sample measuring 1.5 inches, consisting of around 200 hair strands (about the thickness of a #2 pencil) nearest the scalp, yields 100mg of hair, which is the optimal amount for screening and verification. For EtG, additional tests, and/or panels exceeding 10, 150mg of the sample is advisable. We suggest using a jeweler's scale to weigh the sample. If scalp hair is unavailable, an equivalent amount of body hair is acceptable. When mentioning head hair, we specifically refer to scalp hair. Body hair pertains to all other hair forms (facial, axillary, etc.).
Process Overview
The laboratory drug test processing involves four key actions: Accessioning, Screening, Extraction, and Confirmation.
Accessioning commences with processing a sample into a lab's system, including verifying the sample’s proper sealing and shipping, assigning it a random LAN (Laboratory Accessioning Number), and completing any additional data entry not automated by an electronic chain of custody system.
Screening provides an initial rapid assessment for substances of abuse. While Screening is a budget-friendly method to eliminate drug use in most samples, a positive screen must be corroborated to be valid for legal proceedings. Samples with a presumptive positive result in Screening require secondary validation.
If Screening indicates a presumptive positive, additional hair is extracted from the sample for Extraction. During this step, drugs are retrieved from hair at a greatly reduced concentration compared to other methods (e.g., urine or oral fluid), making hair drug analysis the most challenging technique to execute.
Confirmation of any positive screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positives undergo washing before confirmation if necessary. The entire lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair category and the certification to ISO / IEC 17025 standards.

Note: Although often dubbed "hair follicle tests", the analysis focuses on the hair strand rather than the follicle beneath the scalp.
