Caution! Some tests require a chemical preservative in the form of a powder or a strong acid solution. If the container has a preservative, the chemical name will be clearly indicated on the bottle. DO NOT remove the preservative from the container. Keep the container upright to prevent spillage of contents. Urine should not be voided directly into the container. Keep out of the reach of children. If the
chemical preservative in the container is splashed or spilled, refer to first aid measures on the reverse of this pamphlet. Store the container in the dark between 2 - 4 degrees celsius (e.g. in a refrigerator) during the collection procedure.
