Heartworm disease (Dirofilaria immitis) is a serious and potentially fatal condition that affects dogs and cats worldwide. Transmitted by mosquitoes, this parasitic infection can lead to severe heart and lung complications if left untreated. The VetFor HW Rapid Antigen Test Kit by Vitrosens offers a quick, reliable, and easy-to-use method for detecting heartworm infections in pets.
What is Heartworm Disease?
Heartworm disease is caused by the parasitic worm Dirofilaria immitis, which resides in the heart and pulmonary arteries of infected animals. The infection spreads through mosquito bites, making it a prevalent concern in warm and humid climates. Symptoms of heartworm disease in pets include:
- • Persistent cough
- • Fatigue after moderate activity
- • Reduced appetite
- • Weight loss
- • Severe cases may result in heart failure or cardiovascular collapse

The Importance of Early Detection
Detecting heartworm early is crucial in preventing severe health complications. Traditional diagnostic methods, such as blood tests and imaging, can be time-consuming and costly. The VetFor HW Rapid Antigen Test Kit provides a faster and more convenient alternative, enabling veterinarians to diagnose the infection promptly and initiate timely treatment.
