All samples should be sent to the laboratory as soon as possible after they have been taken; delayed transit can affect sample quality.  If this is not possible, then they should be stored in a secure refrigerator at +4°C (do not freeze, unless already frozen, or expose to heat) and sent to the laboratory as soon as possible.


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.

The packaging requirements guide may also be of use.


Samples should be sent to the laboratories as soon as possible (pre-natal samples within 24 hours). Please try to avoid samples arriving at weekends or public holidays; refer to the specific information for particular sample types where appropriate.


All forms of sample transport should deliver the sample directly to the appropriate Genomics Laboratory.

Samples may be delivered by hospital porter, by hand, by external post (first-class only), and by courier. All deliveries should be handed in at sample reception. At Manchester, this is located at the tower 3 entrance (core lift junction 6), on the 6th floor of St. Mary’s Hospital. At Liverpool, this is located within the department which is situated on the 2nd floor of the Jeffcoate Wing of the building.


The laboratories do not provide their own specimen collection service, other than for those patients attending a clinic session with one of our consultants.
