In order to ensure the best possible service may we request that, when submitting samples to the laboratory for analysis, the following advice is followed:
Please Email for advice if unsure about requirements. The following precautions should be noted:
Occasionally a sample is received which is unsuitable for the requested test; this may involve incorrect sample type or clotted, lipaemic or haemolysed samples.
Additional Requested Tests
Separated serum/plasma samples and EDTAs are kept under controlled conditions for six days; thus ensuring any further investigation required can be actioned.
Supplies are FOC unless otherwise stated on the supplies form.
Please refer to our guide below as well as checking the sample requirements stated by the test in the price list.
Allow the sample to clot, then centrifuge and separate serum from the clot and decant into a new plain tube prior to sending. RED CELLS are NOT needed for biochemical tests and presence may artefactually alter results.
Allow the sample to clot, then centrifuge. The gel sits between the cells and serum protecting the serum from any haemolysis. The gel may interfere through possible absorption with the concentration of certain hormones. Some therapeutic drug concentrations are reduced when a sample is stored in a gel tube for greater than 2 hours.
For Haematology EDTA is best for preservation of cell morphology. EDTA is the sample tube of choice for cytology (with a plain tube if culture is required). Please note: EDTA tube samples are not recommended for microbiology submissions as EDTA can inhibit bacterial growth.
Heparin is an anticoagulant which prevents clotting. RED CELLS are NOT needed for biochemical tests and presence may artefactually alter results. Whole heparin is the preferred sample for short samples, e.g. exotics and fractious cats, as it can be used for cell counts with a fresh film. Heparin is not as good as EDTA for preservation of cell morphology.
Used for coagulation testing. It is essential that this tube is correctly filled as the anticoagulant to blood ratio is crucial. The sample may be centrifuged and separated citrated plasma placed in a plain tube. This must then be clearly stated on the form and tube. May also be used for D-Dimer. Separated and frozen citrated plasma must be used for vWF testing.
A spun gel/separated serum sample is the preferred sample for glucose measurement. Spun gel/serum separation should be performed within half an hour of taking the sample. However if using Fluoride Oxalate the tube must be filled to the line.
