Window of Infection

The tool uses the Window of Infection WOI time frame along with the pet’s heartworm test results and matches these with the purchase history of heartworm preventive.

The tool assumes that the first dose of heartworm preventive was given to the pet at the time of purchase, and that the remaining purchased preventive was administered at 30 day intervals.
