Heartworm Testing - Travel Testing
The Heartworm Testing detects Dirofilaria immitis, a parasitic nematode transmitted by mosquitoes that causes heartworm disease in dogs and cats. Antigen testing is the most common and detects proteins released by adult female worms, while microfilariae testing confirms active reproduction. Heartworm testing is crucial for diagnosing infections early, guiding treatment, and monitoring the success of prevention programs. It is especially recommended for annual screening in dogs in endemic areas.
Additionally, this test plays a critical role in pet travel compliance, as some countries require proof of a negative result for heartworm as part of their import regulations.
2 ml Serum
Collect an adequate amount of blood in a plain red-top tube or serum separator tube (yellow-top tube). Allow it to clot at room temperature for 30 to 60 minutes before separation.
Centrifuge to separate the serum. Transfer the clear serum into a new, leak-proof plain red-top tube and label it as "serum."
Excessively hemolyzed samples are not suitable for this test.
Unspun samples will not be accepted.
Refrigerate sample at 4oC until shipment.
Label each sample with the animal’s name and a unique identifier, using a permanent marker or a secure adhesive label
Ensure the submittal form is completed with the animal’s information and relevant medical history.
