We require a minimum of 5ml of urine per sample in a re-sealable container (e.g. screw top vials).
Please ensure all samples are sealed securely to prevent leaking in transit.
Samples should either be mailed in leak proof packaging or absorbent materials should be used within the package in case of leaking.
Following collection, the samples should be stored in a fridge prior to submission. Long term storage should be frozen at ≤-20°C in an upright position to allow for expansion. Samples should be labelled clearly with the volume of the 24h collection and unique sample ID. If there are any clinical details or drug treatments relevant this should be noted. Samples must be shipped in leakproof containers by Royal Mail Special Delivery or by courier.
