Make sure the specimen contains dentinal material. ALT, Inc. will be happy to send any samples along to another laboratory for pathological evaluation free of charge. Since all we do is soak the specimen in water for a brief time and then analyze the extract, our analysis will usually not interfere with subsequent pathological examination. Close the lid tightly and freeze until shipment. Do NOT add water or any liquid.
Zip lock sandwich bags are fine.
Place the larger sealed bag in a padded envelop or wrap it with protective material and place in a box. Complete the Sample Requisition Form for each and every specimen and place it in the envelope or box. Feel free to photocopy the Sample Requisition Form if you need more. If it is not possible to send a specimen the day of the procedure, the specimen may be frozen in the specimen container and sent at a later date. We have observed that teeth and cavitational material stored frozen still retain their toxicity for many months.
