Which statement about the Snap Canine Heartworm Test is true?

• A. It detects antigen produced by female heartworms
• B. It detects microfilariae
• C. It detects adult heartworms
• D. It detects male heartworms

Answer: (A)

The test is designed to detect circulating antigen produced by adult female heartworms. This means a positive result indicates the presence of mature female worms in the dog’s cardiovascular system, not the presence of microfilariae or specifically male worms. If only male worms are present or the infection is very young (before female worms are established), the test may be negative. Microfilariae detection is a different type of test, not what this antigen test targets.
