Accredited Drug Testing offers comprehensive hair follicle drug testing in Memphis, TN. Specializing in hair drug and alcohol tests, we have centers nationwide to perform these tests. At least 1.5 to 2 inches of hair from the head or body is needed in most scenarios. Our hair tests can screen for substances, alcohol/ETG, or other tailored testing options.
In recent times, hair follicle drug testing has become more widespread in drug testing procedures. Many employers, courts, and Substance Abuse professionals prefer it over the typical urine test. This method is crucial for employers with zero-tolerance drug policies, courts, and individuals on probation. The most significant advantage of hair testing is its extended detection timeframe—up to 90 days—with an observed collection process making it nearly foolproof. Yet, for recent usage within 5 days, urine tests remain the most precise.

The examination of hair is recognized as an effective means to identify drug and alcohol consumption. Hair captures a record of alcohol and drug usage over an extended period by embedding biomarkers in the hair strand as it grows. When taken from the area close to the scalp, hair can offer an approximate detection period of up to 3 months for alcohol and other substances. It is straightforward to collect, relatively hard to tamper with, and convenient to transport.
A sample size of 1.5 inches, encompassing about 200 hair strands (comparable to the diameter of a #2 pencil) closest to the scalp, yields 100mg of hair, which is the preferred quantity for both screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, 150mg of the sample is advisable. We suggest using a jeweler’s scale to measure the hair sample. If hair from the scalp is not obtainable, a comparable quantity of body hair can be utilized instead. When mentioning head hair, it specifically pertains to scalp hair. Body hair includes all other forms, like facial and axillary hair.
Process Overview
The four key phases in the laboratory processing of drug test results are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the introductory handling of a sample into the laboratory’s framework. This involves ensuring the sample was securely sealed and shipped correctly, assigning a sequential LAN (Laboratory Accessioning Number), and fulfilling any extra data entry requirements not covered by an electronic chain of custody system.
Screening entails a preliminary rapid assessment for substances of abuse. While Screening serves as a cost-efficient method for eliminating drug usage in most samples, a positive result needs further confirmation to be acceptable in legal contexts. Samples flagged as potentially positive during Screening must undergo additional confirmation.
For specimens marked as potentially positive during the Screening phase, more hair is drawn from the original sample and readied for Extraction. Here, drugs are isolated from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging technique to conduct.
Validation of any positive results from screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are initially positive are washed before confirmation where necessary. The entire laboratory process, from Accessioning to Confirmation, undergoes scrutiny as per the CAP (College of American Pathologists) Hair standards and accreditation under ISO / IEC 17025 norms.
