The Scotia Rapid Test for Diarrhetic Shellfish Poisoning (DSP)

DSP test kit sample



The SRT DSP test is a qualitative lateral flow rapid test for DSP toxins that can be used with bivalves such as mussels, clams and oysters.  This test involves converting the shellfish into a liquid form (known as the extract) which can then be applied to the test.

 This test is used as a screen to reduce the volume of samples being tested by analytical methods. A negative sample will require no further testing. A positive sample should be analyzed by a quantitative method. This screening protocol can significantly reduce the costs associated with analytical testing by government regulators.


The testing method is completed in three basic steps:


Step 1: Prepare sample   

For Shellfish: Remove tissue from the shell and grind till smooth


Step 2: Prepare Extract   

Extraction process converts ground shellfish into a liquid form using the Methanol/Hydrolysis Extraction


Step 3: Proceed to Scotia DSP Test

To test, dilute shellfish extract in the buffer provided with kit and apply sample to the test cassette.

For further details on how to perform the test see DSP testing instructions.
