  • Quality European manufacturing.
  • Low potential for faecal spillage during testing procedure.
  • Storage and testing at room temperature.
  • No additional equipment required.


  • Rapid Immuno-Migration (RIM) Assay for detection of Parvovirus antigen in the faeces of dogs.
  • Point-of-Care test with results in 10 minutes or less.

Recommendations for use:

  • Confirmation of infection with Parvovirus in sick dogs.


  • Remove the top portion, containing the cotton swab, from a sample extraction pipette.
  • Dispense Extraction Buffer into the base of the sample extraction pipette until the buffer reaches the graduation mark.
  • Taking the top portion of the sample extraction pipette, coat the cotton swab with a thin layer of faeces from a stool sample, or an anal swab.
  • Insert the swab into the dispensed extraction buffer in the base of the sample extraction pipette. Securely fit the top portion onto the base and tap to mix for 5 seconds to ensure good sample extraction.


  • Tear open the pouch provided and place the test device on a flat horizontal surface during the migra- tion of the samples.
  • Snap the top of the sample extraction pipette (at the blue line) containing the extracted faecal sample.
  • Invert and hold the sample extraction pipette in a vertical (upright) position and squeeze the base gently to dispense five drops of sample to the sample well (Window (1)).
  • If migration does not pass Window (2) by one minute, add one additional drop of sample in Window (1).


  • Wait 10 minutes, then observe the presence or absence of purple bands in Windows (2) and (3).
  • Sample results are read in Window (2). The control band is read in Window (3).

Notes :

  • The test is complete and may be read before

10 minutes if purple bands are visible in both

Windows (2) and (3).

  • The presence of a purple band only in Window (3) before 10 minutes does not mean that the test is com- plete. A purple band in Window (2) may develop slower

than the control purple band in Window (3).


Negative - A sample is negative for Canine Parvovirus antigen, if there is no purple band visible in Window

(2) and a purple band in Window (3).

Positive - A sample is positive for Canine Parvovirus antigen if there is one purple band visible in Window

(2) and one purple band in Window (3).

Note : A test is valid if a purple band is present in Window (3). If there is no purple band in Window (3), the test is invalid and should be repeated.

Remember : A test result should always be interpreted in the context of all available clinical information and history for the dog being tested.
