Accredited Drug Testing offers comprehensive hair follicle drug testing in Knollwood, Texas. If you require a hair analysis for drugs or alcohol, Accredited Drug Testing has expertise in hair testing, with facilities available Nationwide for conducting these tests. A minimum of 1.5 to 2 inches of hair from the crown of the head or body is typically required. Hair tests are viable for identifying drugs, alcohol/ETG, or other tailored hair testing solutions.
In the past few years, drug testing methods have increasingly incorporated hair follicle drug tests. Many employers, judicial systems, and substance abuse specialists opt for hair drug tests over traditional urine analyses. Hair follicle tests are favored by entities enforcing strict drug-free policies, courts, and probation programs. The major advantage of hair follicle drug tests lies in their ability to detect drug use over an extended period, up to 90 days, through a monitored collection procedure, making them nearly impervious to tampering. Nonetheless, for assessing drug use within the recent 5 days, urine tests remain the most precise option.

Seen as a robust resource, hair testing effectively detects drug and alcohol consumption. Hair strands capture biomarkers within the fibers, yielding a comprehensive history of alcohol and drug usage. When harvested near the scalp, hair offers a detection window that spans roughly 90 days for alcohol and drugs. Hair is uncomplicated to gather, relatively resistant to tampering, and straightforward to send.
Collecting a 1.5-inch segment of around 200 strands of hair nearest the scalp results in 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, or those exceeding 10 panels, 150mg of the sample is recommended. It is advised to utilize a jeweler's scale to weigh the sample. If scalp hair is absent, an equal quantity of body hair can be gathered. "Head hair" pertains solely to scalp hair, whereas "body hair" encompasses all other types (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four essential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning signifies the preliminary integration of a sample into a laboratory's framework. This step includes confirming that the sample was correctly sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and performing any supplementary data entry that an electronic chain of custody system doesn't cover.
Screening serves as an initial, rapid assessment for drug misuse. While cost-effective, a positive screening outcome must be verified to be valid in a court of law. Samples that test presumptive positive during Screening need follow-up confirmation.
Presumptive positives during Screening prompt additional hair to be taken from the primary sample for the Extraction process. During Extraction, drugs are isolated from hair at a considerably lower concentration than other techniques (e.g., urine or oral fluid), rendering hair drug screening as the most complex methodology.
Positive results from screening undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before Confirmation as deemed necessary. The complete laboratory sequence from Accessioning through to Confirmation complies with CAP (College of American Pathologists) Hair designations and ISO / IEC 17025 accreditation.
