Taking and sending samples
Blood samples
All BLOOD samples for cytogenetic analysis should be sent in Lithium Heparin containers (green or orange top)
If microdeletion studies are required please send at least 1ml blood in EDTA IN ADDITION to the lithium heparin sample. If there is not enough blood for two samples send only lithium heparin, but this may compromise the test.
Other samples
Transport media is supplied for transport of bone marrow, tumour and tissue samples to the laboratory - see information on our ordering medium page. If the sample is not to be sent immediately, please keep refrigerated.
Amniotic fluid should be sent in a sterile universal. CVS samples should be sent in appropriate transport medium, details of which can be obtained from the laboratory (01132065419).

Please note
• The final decision on whether to accept a specimen will lie with the Head of the Laboratory.
• Sample Collection: It is the responsibility of the person (doctor, nurse or phlebotomist) taking the sample from the patient to ensure that the specimen container is correctly identified.
• Transportation of Specimens: It is the responsibility of the person transporting the specimen to ensure that it arrives promptly and undamaged at its destination.
• The laboratory responsibility begins when the specimen arrives at Cytogenetics/Pathology. The Cytogenetics Unit can only act upon the information provided and upon the accuracy of that information.
Samples with High Risk of Infection
• It is important that known high risk of infection specimens are appropriately labelled. This will allow the laboratory to make a suitable risk assessment, and apply relevant local precautions in respect of trainee and junior staff, pregnant staff, and those who have recently given birth, so as to ensure staff health safety and welfare.
• In order to comply with existing Health & Safety Advisory Committee guidelines and legislative requirements, the use of ‘danger of infection’ labels for specimens known or suspected to carry a blood born virus is strongly recommended.
• Request cards that are incomplete can lead to delays in processing, or the wrong test being carried out.
• Request cards can be obtained from:
Cytogenetics Unit,
St. James’s Hospital,

• Samples should be sent in sealed plastic bags, with the request card protected from the sample.
• The plastic bags should be placed in taped boxes containing appropriate padding and packing.
• All referrals should clearly show the address of the Leeds Cytogenetics laboratory.
