Product Information

¤  INTENDED USE

The Canine Heartworm Antigen Rapid Test is a test cassette to diagnose the presence of Dirofilaria immitis antigens (CHW Ag) in dog’s blood specimen.

Assay Time:  5-10 minutes

Specimen: Serum, plasma or whole blood

¤  TEST PROCEDURE

- Allow all materials, including specimen and test device, recover to 15-25℃ before running the assay.

- Take out the test device from the foil pouch and place it horizontally.

- Using the capillary dropper to place 10μL of the prepared specimen into the sample hole “S” of the test device. Then drop 2 drops (approx. 80μL) of the assay buffer into the sample hole immediately.

- Interpret the result in 5-10 minutes. Result after 10 minutes is considered as invalid.

Q&A

¤  What is Canine Heartworm disease?

Heartworm disease is a serious disease that results in severe lung disease, heart failure, other organ damage, and death in pets, mainly dogs, cats, and ferrets. It is caused by a parasitic worm called Dirofilaria immitis.The worms are spread through the bite of a mosquito.  The dog is the definitive host, meaning that the worms mature into adults, mate, and produce offspring while living inside a dog.  The mosquito is the intermediate host, meaning that the worms live inside a mosquito for a short transition period in order to become infective (able to cause heartworm disease).  The worms are called “heartworms” because the adults live in the heart, lungs, and associated blood vessels of an infected animal.

¤  What are the signs of heartworm disease in dogs?

In the early stages of the disease, many dogs show few symptoms or no symptoms at all. The longer the infection persists, the more likely symptoms will develop. Active dogs, dogs heavily infected with heartworms, or those with other health problems often show pronounced clinical signs.

Signs of heartworm disease may include a mild persistent cough, reluctance to exercise, fatigue after moderate activity, decreased appetite, and weight loss. As heartworm disease progresses, pets may develop heart failure and the appearance of a swollen belly due to excess fluid in the abdomen. Dogs with large numbers of heartworms can develop a sudden blockages of blood flow within the heart leading to a life-threatening form of cardiovascular collapse. This is called caval syndrome, and is marked by a sudden onset of labored breathing, pale gums, and dark bloody or coffee-colored urine. Without prompt surgical removal of the heartworm blockage, few dogs survive.

¤  Can People Get Heartworms from Their Pets?

People cannot get heartworms from their pets.  Heartworms are only transmitted by the bite of an infected mosquito.  In rare cases, people can get heartworms after being bitten by an infected mosquito.  But because people are not a natural host for heartworms, the larvae usually migrate to the arteries of the heart and lungs and die before they become adult worms.
