1. Collect specimen prior to discharge from hospital or by seven days of age, whichever comes first
2. To prevent contamination, DO NOT touch any part of the filter paper circles before, during or after collection
3. For puncture: wipe away the first drop of blood. Allow sufficient blood to collect on the heel to fill each circle by a single application of paper to a drop of blood
4. Apply only from one side of the filter paper. Blood should soak all the way through the paper such that the blood spots look similar on both sides. The entire circle should be saturated
5. DO NOT superimpose the blood drops on top of each other or oversaturate circle.
Handling InstructionsAir dry the blood specimens at room temperature for 3-4 hours in a horizontal position. DO NOT dry on a heater or microwave. Mail to Washington State Department of Health within 24 hours of collection. DO NOT batch specimens collected on separate days.
