Start it off my journey, trying to save a buck bought the twenty dollar kit off amazon.Looked pretty similar, NOT! So being cheap did not help. PurchaseThis kit got a small discount for being a first time customer. Bonus. Directions were simple, pricked her lip, collected all the blood on the swab. Put the swab in the solution and set a timer. Then, put a couple drops on the test strip set a timer. Negative. We confirmed it a week later with an x ray. In the future, I will definitely consider this brand again.
