Frequently Asked Questions

What drug tests are available and what compounds do they detect?

Array technology sounds interesting, but my lab does not routinely screen samples for 12 drugs. Can the MTA-12™ be customized with fewer assays for my lab's specific needs?

What equipment is required to run the test?

What materials are required but not supplied?

What alternative matrices are supported?

Can I run both blood and urine? Is any sample preparation required prior to analysis?

Can I run less than a full plate?

What is the shelf life of the kit and how long can I use it if the bottle has been opened?

How should I store the kit?

 

What drug tests are available and what compounds do they detect?

Assays available from Venture Labs include: Amphetamine, Barbiturates, Benzodiazepines, Buprenorphine, Cannabinoids, Cocaine, Fentanyl, Ketamine, MDMA, Methadone, Methamphetamine, Opiates, Oxycodone, Phencyclidine, Propoxyphene, Tramadol, and Tricyclic Antidepressants. All assays are calibrated with the active/parent drug and are designed to detect both parent and metabolite drug forms. For assays such as Benzodiazepines and Barbiturates, the assays recognize a broad class of compounds. Please refer to the Specificity and Cross Reactivity sections for individual assays of interest to see a detailed list of what compounds are detected at various concentrations.

Array technology sounds interesting, but my lab does not routinely screen samples for 12 drugs. Can the MTA-12™ be customized with fewer assays for my lab's specific needs?

Yes, any combination of 4 or more of the following assays can be custom-configured into the array format to meet your labs specific needs: Amphetamine, Barbiturates, Benzodiazepines, Buprenorphine, Cannabinoids, Cocaine, Ketamine, MDMA, Methadone, Methamphetamine, Opiates, Oxycodone, Phencyclidine, Propoxyphene, Tramadol, and Tricyclic Antidepressants. Custom Multi-Test Arrays use the same procedure as the MTA-12™ kit.

What equipment is required to run the test?

The only required equipment is a standard, 96-well microtiter plate reader. No other specialized laboratory equipment is necessary.

What materials are required but not supplied with the kit?
The following materials are required but not supplied:
  • Single channel pipettes and tips for dispensing 30 uL and 75 uL volume.
  • Multichannel pippettes and tips for dispensing 50 uL and 100 uL volumes
  • Graduated cyclinder for measuring 450 mL
  • Distilled water
  • Squirt bottle (500mL or larger) for dispensing rinse solution
  • Reagent reservoir
  • Clock or timer
  • Microplate washer (optional)
  • Absorbent toweling
  • Microtiter plate reader
  • Assay standards
What alternative matrices can be used in this test?
Sensitivity of the MTA-12™ assay is suitable for forensic applications of alternative specimens. Collection and/or extraction methods of alternative specimens vary from lab to lab. Therefore, each lab must validate the usability of the different alternative specimens to be analyzed in the lab with the MTA-12™ method. For more information, please contact Venture Labs technical support.

Can I run both blood and urine? Is any sample preparation required prior to analysis?
Yes, Venture Labs assays have performance characteristics suitable for running both blood and urine samples. High sensitivity to parent drug forms allows a lab to run blood samples neat; i.e., without extraction. While the assays also detect the metabolite drug forms present in urine specimens, often the high sensitivity of Venture's assays exceeds desired urine cut-off concentrations. Prior to analysis, urine samples may be diluted with negative urine or buffer to bring them into the desired concentration ranges.

Can I run less than a full plate?
Yes. The strips can be removed from their trays and broken apart to accommodate your testing needs.

What is the kit's shelf life, and how long can I use the kit after the bottles are opened?
Opened or closed, the MTA-12™ drug test system kit is stable for 1 year from date of manufacture under recommended storage conditions. Please check the expiration date on the lower-right-hand corner of the kit label. The expiration date can also be found on the profile card that is included in the kit.

How should I store the kit?
The liquid reagents should be stored refrigerated at 2-8ºC. the microtiter plates can be stored at room temperature in the sealed foil pouch with the accompanying desiccant pack. Once diluted, the rinse solution can also be stored at room temperature.
