• First name, Surname, Date of birth, Hospital/Clinic number, Medical Record Number (MRN) are examples of patient identifiers

• Time and Date of collection of samples

• Type of sample and Anatomical site, where appropriate (e.g. swabs)

• Relevant clinical information

• Relevant details of medication

• High-risk Samples should be clearly identified on the form and individually packed separately from other samples

• Known cases of Hazard Group 4 pathogens such as Ebola or Viral Haemorrhagic Fever must NOT be sent to the laboratory. If there Is doubt about a patient’s symptoms and presentation please contact the Imported Fever Service on 0844 778 8990 for advice before sending samples to TDL or any laboratory.
