The Scotia Rapid Test for Amnesic Shellfish Poisoning (ASP)

The SRT ASP test is a yes/no rapid test for ASP toxins that can be used with bivalves such as mussels, clams, oysters.  This test involves converting the shellfish into a liquid form (known as the extract) which can then be applied to the test.

The SRT ASP test is simple and easy to use and can be performed easily in a seafood processing plant, shipboard or dockside. It is fast and can give quick reliable results of seafood ready to be processed or a catch fresh off the ship.

The testing method is completed in three basic steps:


Step 1: Prepare sample

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

For Algae : Filter seawater and collect algal cells


Step 2: Prepare Extract

For Shellfish: Extraction process converts ground shellfish into a liquid form using one of three methods:

  1. Positive results obtained in a regulated environment will need further analytical testing by High Performance Liquid Chromatography (HPLC). This will require using the AOAC Extraction.
  2. Positive results obtained in a regulated environment will need further analytical testing by Liquid Chromatography Mass Spectrometry (LCMS).  This will require using the Methanol Extraction.
  3. If further testing is not required, then use Rapid Extraction.


For Algae:

Extraction process converts the collected algal cells to liquid form using the Phyto Extraction.


Step 3: Proceed to Scotia ASP Test

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

For further details on how to perform the test see ASP AOAC , ASP Methanol, ASP Rapid or ASP Phyto testing instructions.
