Sending Samples by Post

There are some absolute requirements for sending samples through the UK postal system. Blood samples cannot be posted outside the UK without an export license - use a large lab to send your sample as they will have the required licensing.

Packaging samples should follow the guidelines required by Royal Mail, namely:

• The maximum weight or volume permitted in any one package of diagnostic specimens is 50g/50ml. Samples that exceed this limit need to be packaged into several smaller packages rather than one large one.
• Use leak proof containers – seal the lid with a little parafilm or tape to ensure this. Label the sample accurately and in permanent ink including the sample type (e.g. blood, urine etc). Make sure samples preserved in Formalin are marked as such (in case of breakage during transport).
• Package the sample with sufficient tissue paper or cotton wool to absorb the entire contents of the sample should there be a leak whilst in transit. Always package bloods tubes/containers individually so they are kept separate from one another.
• Seal your wrapped sample in a separate outer packaging that is leak proof such as a sealable plastic bag.
• Place the sample and the lab request form into an envelope or jiffy bag that is clearly labeled in permanent ink ‘Diagnostic Specimen’.
• It is advisable (but not required) to add a returns address so that the practice can be contacted in the event of any problems.
