Drug & Alcohol Testing in San Antonio

MD Toxicology has over 60 years of combined experience conducting drug and alcohol tests with verified reliable data pinpointing the positive drugs found from each test.

Drug or Alcohol testing is a technical analysis of a biological specimen, for example urine, hair, blood, breath, sweat, or oral fluid/saliva—to determine the presence or absence of specified parent drugs or their metabolites.

Drug testing includes detection of the presence of performance enhancing steroids in sports, employers screening for drugs prohibited by law (such as cannabis, cocaine and heroin) and police officers testing for the presence and concentration of alcohol (ethanol) in the blood commonly referred to as BAC (blood alcohol content).

BAC tests are typically administered via a breathalyzer while urinalysis is used for the vast majority of drug testing in sports and the workplace.

Why Urine Testing?

Urine Testing

Urine analysis is primarily used because of its low cost. Urine drug testing is one of the most common testing methods used. The enzyme-multiplied immune test is the most frequently used urinalysis. Complaints have been made about the relatively high rates of false positives using this test.

Urine drug tests screen the urine for the presence of a parent drug or its metabolites. The level of drug or its metabolites is not predictive of when the drug was taken or how much the patient used.

Rather, it is simply a confirmatory report indicating the presence of the parent drug or its metabolites.

5 Panel Urine Test

A 5-panel test is the most common workplace drug test. It is used by local, state and federal companies and government agencies including the DOT. It tests for marijuana, cocaine, amphetamines, opiates(Heroine) and phencyclidine (PCP).

Common pain medications such as codeine, morphine and oxycodone are also tested in the opiate category.

  • Marijuana
  • Cocaine
  • Amphetamines
  • Meth-Amphetamines
  • Opiates
  • Heroine

10 Panel Urine Test

The 10 panel drug test is used by private employers. Non-union companies can require their employees to take this type of test, while union based companies must work the unions to show grounds for reasonable suspicion.

 This test screens a total of 10 drugs. It allows an employer to determine the health status of new and existing employees.

  • Same 5 in 5 Panel Tests plus . . .
  • Barbiturates
  • Benzodiazepines
  • Methadone
  • Methaqualone
  • Propoxyphene

Additional Urine Testing Information

The process typically starts when a new or existing employee is asked by the employer that a drug and alcohol screening appointment has been requested. At MD Toxicology we are award of the sensitive and personal concern that an individual being asked to take a drug test will go through. We make the process very straight forward, non obtrusive and quick.

Upon arrival at our facility the average wait time is less than 30 minutes. Your urine sample will be given in a tamper proof container and sealed with tape and labeled for testing.

Urine test is not conclusive because often times an employee, trying hide a positive result, will tamper with testing procedures the most common being bringing in a negative result sample. The United States Department of Transportation (DOT) requires lab technicians to also test for low temperature or show signs of alteration. Upon suspicion of the first sample a second sample will be required with visual sample by the lab technician.

Oral Fluid/Saliva Testing

Saliva / oral fluid-based drug tests can generally detect use during the previous few days. Is better at detecting very recent use of a substance. THC may only be detectable for 2–24 hours in most cases. On site drug tests are allowed per the Department of Labor. Detection in saliva tests begins almost immediately upon use of the following substances, and lasts for approximately the following times:

  • Alcohol: 6-12 Hours
  • Marijuana: 1-24 Hours

A disadvantage of saliva based drug testing is that it is not approved by FDA or SAMHSA for use with DOT / Federal Mandated Drug Testing. Oral fluid is not considered a bio-hazard unless there is visible blood; however, it should be treated with care.

Hair Testing

Saliva / oral fluid-based drug tests can generally detect use during the previous few days. Is better at detecting very recent use of a substance.
