NutriPATH requires a minimum 48 hour booking notification for dry ice time sensitive collections. It is advisable that you do not request collections on a Friday as this may affect transit times. Once you have submitted your requested collection date, a NutriPATH representative will be in contact with you with your confirmation booking number and consignment note. Please note: The collection address provided is the address that the samples will be collected from. Urinary Kryptopyrrole collections should be couriered on a Tuesday, Wednesday or Thursday. This booking page cannot be used for ALCAT sample collections.
