 | Why This Test Matters |
✓ Detects active infection through direct molecular testing
✓ Useful when antigen results are inconclusive or discordant
✓ May support detection in early-stage or low-burden infections
✓ Helps improve diagnostic confidence in clinically suspicious cases
✓ Adds value when heartworm disease is suspected despite negative screening results
 | When Should This Test Be Ordered? |
The Heartworm PCR test may be considered when:
• Routine screening prior to initiation or continuation of heartworm prevention
• Cases where early infection is a concern (pre-antigen stage)
• Patients with negative or inconclusive antigen results but ongoing clinical suspicion
• Detection of occult or low-burden infections
• Situations requiring enhanced diagnostic sensitivity
• Follow-up evaluation in complex or uncertain cases
