Types of Drug Tests Available

Urine Drug Test

A urine drug test, also known as a urine drug screen or a UDS, is a painless test. It analyzes your urine for the presence of certain illegal drugs and prescription medications.

Given that everyone functions differently, there are numerous factors that may influence how long drugs remain in the system.

Some of these factors include:

  • The amount of drugs consumed
  • Metabolic rate
  • Volume of fluids excreted following drug use

Except for marijuana, which can leave detectable taint in the urine for up to a week

or up to a month, most illegal substances remain in the urine for up to a week. Many employers require potential employees to take a urine drug test before they can be hired as a pre-employment requirement. Optimal Lab Houston provides solutions to all of your employer and personal needs and maintains 100% confidentiality to your test results. We are a trusted provider for drug testing in Houston through our reliable Houston drug testing lab.

Hair Drug Test

A hair follicle drug test, also known simply as a hair drug test, screens for illicit drug use and the misuse of prescription medication. This testing method is ideal for detecting prolonged drug use, up to three months, because the chemicals from drugs that enter the bloodstream become part of the hair cells as your hair grows.

A person may need to undergo drug testing for employment, legal, or medical purposes:

  • Some companies require prospective employees to submit to a drug test during the application process, especially for jobs with a high risk of injury.
  • Employers may conduct random drug tests on current employees.
  • Drug tests may also be requested following serious accidents or incidents.
  • Courts may require drug testing during probation, child custody, adoption, or domestic violence cases.

At Optimal Lab Houston, we provide both walk in drug test in Houston services and same day drug screening, meeting both employer and personal testing needs while maintaining complete privacy. We offer multiple panel tests to screen for various illegal substances efficiently and confidentially.

NAIL DRUG TEST

This testing is used to reveal a history of drug use rather than recent consumption.

  • Fingernail samples can typically provide drug use history up to 6 months.
  • Toenail samples may provide a history of drug use for up to 1 year.

Nail samples only have a weight requirement.

  • If each finger has 2 to 3 millimeters of nail growth beyond the nail bed, a sufficient sample can usually be collected.

At Optimal Lab Houston, we deliver fast and accurate drug testing in Houston using nail samples.

  • Our clean, professional environment ensures comfort and privacy.
  • Our certified collectors offer prompt, courteous service.
  • We offer both 5-panel and 10-panel options for lab drug test, screening for multiple illegal substances with precision.

Breath Alcohol test

A breath alcohol test determines the concentration of alcohol in your blood by measuring the alcohol in the air you exhale. Once consumed, alcohol is absorbed into the bloodstream through the stomach and small intestine. It travels throughout the body, including the lungs, which is why it can be detected in your breath.

This test shows your current level of intoxication or impairment, it does not detect past use, unlike most drug testing methods.

  • A blood alcohol content (BAC) of 0.2 or above is considered a positive result.

At Optimal Lab Test Houston, we use DOT-approved Evidential Breath Testing devices (EBTs) handled by certified personnel.

  • We offer same day drug screening and walk in drug test in Houston for both personal and employer requirements.
  • All test results are kept 100% confidential, ensuring your privacy and peace of mind.

Saliva Alcohol Test

Optimal Lab Test Houston also offers the saliva specimen alcohol test, commonly known as the oral fluid alcohol test. This test is designed to detect current or recent alcohol consumption, typically identifying alcohol use within 24 to 48 hours after intake.

This method is especially popular with employers due to its affordability, simplicity, and non-invasive collection process.

  • Saliva collection is quick and hassle-free, making it one of the easiest types of alcohol testing available.

From Houston drug screening to getting the results, you can rely on us for every step.

Urine Alcohol Test

The urine alcohol test detects the presence of EtG (ethyl glucuronide) in the urine. EtG is a byproduct of alcohol metabolism in the body and can be detected for up to 80 hours after alcohol ingestion.

This test provides a simple and low-cost method to determine recent alcohol consumption. It is widely used to monitor alcohol abstinence in cases where alcohol use is not permitted.

Common uses include:

  • Court cases (e.g., child custody)
  • DUI or DWI program
  • Liver transplant patients2
  • Probation programs
  • Professional monitoring programs (for example, airline pilots, healthcare professionals, attorneys)
  • Schools or the military

Hair Etg Alcohol Test

A hair alcohol test is performed to detect the presence of EtG, a byproduct of alcohol metabolism, in the hair. EtG hair follicle testing can detect alcohol consumption for up to 90 days.

Since EtG tests provide a historical indicator of alcohol use, they are commonly used in:

  • Court-ordered probation
  • Child custody proceedings
  • Substance abuse treatment programs

Optimal Lab’s lab drug test in Houston offers reliable and confidential hair alcohol testing for both personal and legal purposes.
