SAMHSA Certified Laboratory

Melody’s Southwest Consortium is a licensed and certified administrator for the Department of Transportation. We only use certified laboratories, which provide superior protection and limit liability. (Alere, Redwood, Omega, Quest, etc.)

Medical Review Officer (MRO)

A Medical Review Officer (MRO), our licensed physician who is responsible for receiving and reviewing laboratory results generated by an employer’s drug testing program and evaluating medical explanations for certain drug test results. The MRO acts as an independent and impartial “gatekeeper” and advocate for the accuracy and integrity of the drug testing process.


Urine testing remains the industry standard for drug testing because of its accuracy, reliability, ease of collection and relatively low cost, other options are available at Melody’s Southwest Consortium.

Breath Alcohol Testing

We are proud to offer alcohol testing using the finest Breathalizer equipment available by our highly-trained Breath Alcohol Technicians. In cooperation with Intoximeters, we operate a renowned training program for breath alcohol technicians and are widely regarded as experts in the breath-testing field.

Urine Alcohol Testing

A relatively new alcohol testing methodology (10 years old) - EtG, or ethylglucuronide, is a byproduct of ethanol (alcohol that one drinks) and glucuronide a common biological compound made in the liver that binds various toxins and drugs in the body that allows them to be excreted in the urine. When someone drinks, even relatively small amounts of alcohol, EtG is formed and can be detected in the urine for up to 3 days AFTER drinking alcohol.

Hair Testing

Though significantly more expensive than urine testing, hair testing allows one to test for drug use for a much longer period of time. As a general rule, for each inch and a half of hair, one can test use seven to ninety days back. We recommend an additional urine test to cover the seven days immediately before the test.

Instant/Rapid Urine Testing

Most of our NON DOT testing panels are available with instant screening results. However, the law requires that all non-negative employment drug tests must be confirmed at a laboratory before an employer can use the results to make employment decisions.

Oral Fluid (Saliva)

Oral fluid testing analyzes a saliva sample for drugs and their metabolites. An absorbent collection device is placed in the mouth and the saliva collected is screened for drugs of abuse. Though less invasive collection procedures than urine testing, oral fluid testing has a limited time window of detection for drug use.


Finger or toe nails, produced with a keratinized protein like hair, is emerging as a popular specimen type for drug and alcohol testing. Drugs are deposited in the nails through absorption into the root of the growing nail bed. Because fingernails and toenails take 3 to 6 months to grow from the nail bed to tip of the finger or toe, traces of drugs will remain in the nails longer than in the urine, hair, saliva, or blood -thus providing a much longer detection window. Because fingernails and toenails cannot be tampered with, the nail drug test ensures accurate results that are convenient and non-invasive.


Desperate employees often go to great lengths to subvert a drug test, including purchasing synthetic urine products. Our specimen collectors, some of the best in the nation, are extensively trained to recognize synthetic urine. Also, our labs are capable of testing specimens to determine if they are legitimate or synthetic. Though companies who produce these products say they guarantee a negative test result, in our system, these products generally fail.

Trending Drugs

Currently, synthetic marijuana (Spice / K2) and synthetic amphetamines (Bath Salts) are trending dramatically, and we offer testing for all related compounds. Melody’s Southwest Consortium makes it a mission to stay abreast of current drug trends and offer testing as soon as it becomes available.  Synthetic Drug Tests will test for the presence or absence of variations of the designer drugs known on the streets as “Spice”, “K2”, “Salts”.

Further testing may be necessary, as synthetic drugs generally will not be detected in a standard drug test, such as a 5 or 10 Panel Urine or Oral Fluid Test.

Prescription drugs such as hydrocodone, oxycodone, and methadone remain a constant worry in the workplace, thus Melody’s Southwest Consortium’s official recommendation to all employers is to test for all synthetic and semi-synthetic opiates as part of their opiates testing panel.
