Sample Delivery


The sample and referral form should be sealed separately in a biohazard bag to prevent contamination of paperwork in the event of leakage. Blood samples should be packaged according to UN3373 standards.

High risk samples must be clearly identified and all packaging must conform to UN650 standards.  Blood samples should be packaged according to UN3373 standards.

This guide to packaging requirements may also be of use. We gratefully acknowledge Cheshire & Merseyside Regional Genetics Laboratory’s kind permission to use this document.


Samples should be sent to the laboratories as soon as possible (pre-natal samples within 24 hours, preferably no later than 4.00pm). Please try to avoid samples arriving at weekends or public holidays; refer to the specific information for particular sample types where appropriate.

Note that the Willink Metabolic Unit offers an out-of-hours service.
