If you are requested to provide a specimen, this may be left at reception in the specimen drop hatch any weekday before 15:00 (except semen samples which must be taken direct to the Norfolk and Norwich University Hospital on a Monday, Tuesday or Wednesday).

Please ensure that the specimen containers are correctly labelled with your full name, date of birth and the date the sample is collected, as the laboratory will not carry out investigations on unlabelled or incorrectly labelled specimens.
