? Store BD Trucount tubes in their original foil pouch at 2° to 25°C. To avoid potential condensation, open the pouch only after it has reached room temperature and carefully reseal the pouch immediately after removing a tube. Examine the desiccant each time you open the pouch. If the desiccant has turned from blue to lavender, discard the remaining tubes. An unopened pouch is stable until the expiration date shown on the packaging. Do not open and use tubes after this expiration date. Use tubes within 1 hour after removal from the foil pouch. Use remaining tubes within 1 month after opening the pouch.
