Our Services

Rapid turn-around is critical to the needs of our customers, therefore Diversified offers three different reporting services:

  • Standard - Next Day -               Results by 5:00 pm EST the day after sample is received
  • "Red Dot" - Same Day -          Results by 5:00 pm EST the same day the sample is received
  • "Double Rush" - Same Day -   Results by 2:30 pm EST the same day the sample is received

Pesticide/PCB/Chlorinated Hydrocarbon Screen

Diversified Laboratories offers the most comprehensive standard screen available in the United States for poultry and livestock:

  • 47 individual pesticides
  • 17 chlorinated compounds
  • 8 individual polychlorinated biphenyl (PCB) products.

As new compounds are found in samples submitted to the laboratory, research is done to identify the substances and we then include them in our routine screen. If there is possible contamination outside of our routine screening, Diversified offers complete analytical services to identify the substance and solve the problem. We also confirm other laboratory results using advanced gas chromatography and mass spectrometry techniques.

For routine screening purposes, the limits for reporting specific values range from 0.002 ppm to 2.50 ppm, depending upon the pesticide in question and the type of sample analyzed. A comprehensive summary of reporting limits and detectability limits for routine screens is available upon request. In addition, special methodologies can be employed to lower the limits for quantitative reporting to one tenth of the levels shown.

Pesticides Included in the Complementary Organophosphate Pesticide Screen

Diversified Laboratories offers a separate standard complementary screen of 18 of the most common organophosphate pesticide residues. The list of available organophosphate pesticides numbers in the hundreds and a comprehensive screen for all of them is not economically feasible. However, as new compounds are found in samples, we identify the substances and include them in the routine screen. 

Below is a list of the 64 pesticides/chlorinated hydrocarbons, 8 PCB products and 18 organophosphate pesticides we screen for.
