Product description

Witness Heartworm detects the soluble antigen D. immitis in dog or cat blood. The test is recommended for use when clinical history and/or signs suggest heartworm disease or where a rapid verification of heartworm infection is required.

Active ingredients

Witness Heartworm kit contents:

  • 10 or 25 Pouches, each containing 1 test device and desiccant.
  • 10 or 25 Pipettes.
  • 1 Saline Buffer dropper bottle (5.0 mL)
  • Instructions for use.

Indications for use

  • Witness Heartworm is a simple test based on Rapid Immuno Migration (RIM™) technology, which detects the presence of adult D. immitis antigens in dog or cat blood.

  • Sensitized particles bound to heartworm antigens present in the sample (whole blood, serum or plasma) migrate along a membrane.

  • The complex is then captured on a sensitized reaction zone where its accumulation causes the formation of a clearly visible pink/red band.

  • A control band located at the end of the reading window (3) ensures that the test was performed correctly.

Administration and dosage

  • Sample application:

    • Tear open a pouch provided and place the test device on a flat horizontal surface.
    • Holding the provided pipette vertically, add one drop of sample to the test well.
  • Buffer dispensing:

    • Check that the sample has fully absorbed into the membrane.
    • Remove the cap from the buffer bottle, hold it vertically and add two drops of buffer to the test well.
    • Leave the test device flat during migration of sample/reagent complex through the reading windows.
  • Reading test:

    • After 10 minutes, observe the presence or absence of pink/red bands in the reading windows (2) and (3).
