Toilet water and urine cannot be combined with stool. Within 1 hour of collection transfer the stool into an orange-labeled Para-PakĀ® vial using the spoon affixed to the vial cap, taking care not to let the volume in the vial exceed the RED fill-line on the side of the label. Do not overfill. Cap the vial and shake 10 times to ensure complete distribution of the stool into the preservative.
