Urine drug testing remains the most prevalent method across Charleston, SC and the U.S., being the sole option sanctioned for DOT-regulated drug testing under 49 CFR Part 40. This technique discerns recent drug use by assessing a urine specimen for traces of drugs, metabolites, or alcohol biomarkers. The procedure is uniform, secretive, and built to furnish accurate, legally sound outcomes for businesses, individuals, and judicial mandates.
Testing Methods & Collection Process
1. Donor Identity Verification
The donor provides authorized identification and adheres to chain-of-custody protocols prior to testing commencement.
2. Secure Collection Environment
Samples are gathered in controlled settings preventing tampering, with potential restrictions on personal items and secured facilities.
3. Chain of Custody Documentation
A national Chain of Custody Form (CCF) follows the specimen, upholding the test's integrity and legitimacy.
4. Temperature & Validity Checks
Right after collection, samples undergo temperature and appearance checks, alongside validity assessments in labs, including creatinine and pH evaluations.
5. DOT Split Specimen
DOT tests divide urine into two containers, where non-DOT requires only one for accuracy and possible retesting.
6. Laboratory Screening & Confirmation
Utilizing SAMHSA-certified laboratories for two-phase analysis, employing:
7. MRO Verification

Hair drug and alcohol analysis offers a robust long-term view into an individual's substance use history. Unlike urine testing, which captures recent use, hair testing examines drug metabolites ensconced within the hair cuticle, accruing a detailed 90-day detection span. This distinction makes hair testing ideal for contexts where long-term usage patterns are required, such as workplace screening in Charleston, SC, legal matters, child custody hearings, and compliance evaluations.
While timelines differ from quicker urine tests, hair analysis delivers unparalleled accuracy and consistency.
In its application, though hair testing has temporal initiation limits and is more cost-prohibitive, its efficacy in profiling patterns over time makes it indispensable.

An alcohol urine test discerns recent alcohol use by detecting ethanol by-products in urine. This is a prevalent mechanism for workplace assessments, judicial demands, and post-incident circumstances. While it doesn't gauge immediate intoxication levels, it presents a brief window of detection spanning a few hours, offering a swift and economically sensible assessment option.
The EtG (Ethyl Glucuronide) urine test is an exceedingly sensitive platform for identifying alcohol use extending up to 80 hours post-consumption. Owing to EtG's nature as a direct ethanol by-product, this test gains considerable usage in courts, rehab setups, and surveillance organizations. It grants a broader detection timeframe than standard urine alcohol assessments and is renowned for its precision and trustworthiness.
A breath alcohol test evaluates contemporary impairment by analyzing alcohol concentration within deep lung air. Such tests are executed via DOT-endorsed breath alcohol tools (EBTs), yielding prompt and legally respected outputs. Breath evaluations are mandated for DOT-assigned personnel and are habitually employed for worksite, post-incident, and suspicion-based testing.
A blood alcohol test quantifies the current ethanol presence in the bloodstream, positioning it as a highly precise tool for impairment evaluation. Hospitals, law enforcement entities, and legal firms rely on blood alcohol assessments for their accuracy, especially in DUI circumstances, urgent medical care, and crucial legal probes.
The PEth (Phosphatidylethanol) blood test highlights chronical or heavy alcohol consumption, unveiling specific alcohol markers within red blood cells. PEth can capture usage up to 2-3 weeks prior and is esteemed as one of the steadiest indicators of prolonged drinking conduct. This test frequently finds application in family law contexts, surveillance setups, treatment institutions, and safety-centric employments assessments.
The EtG hair alcohol test encompasses a 90-day detection phase by evaluating alcohol by-products assimilated in the hair shaft. This form of testing marks recurring or incessant alcohol intake instead of singular episodes. Judicial setups, child custody disputes, and prolonged surveillance programs depend on hair EtG assessments given their endurance, exactitude, and resistance to interim sobriety initiatives.
