IDEXX heartworm test for cats is read at how many minutes?

• A. 10 minutes
• B. 8 minutes
• C. 12 minutes
• D. 15 minutes

Answer: (A)

Reading time is crucial for rapid immunoassays such as the IDEXX heartworm test because the test line develops as the assay runs and must be read within a specific window to be interpreted reliably. For the feline heartworm test, IDEXX specifies a 10-minute read time. Reading too soon can miss a developing positive line, while waiting too long may introduce nonspecific lines or background color that confuses interpretation. Always follow the manufacturer's timing to ensure accuracy.
