Blood tests - haematology and biochemistry

Haematology

The laboratory uses a Nihon Kohden Celltac haematology analyser, which is a particle counter based on the 'Coulter' principle, to measure the haemoglobin content and the cellular constituents of the blood.

This veterinary analyser counts white cells, red cells and platelets having variable thresholds to allow for the different cell sizes of the species we test. A size distribution histogram is displayed for each sample helping the operator to identify any artifactual errors which veterinary samples are prone to.

This analyser is also used for cell counts on a variety of samples such as joint, tendon sheath and peritoneal fluids.

The accuracy of the automated cell counter is complemented by the cytology, including the white cell differentials on blood smears, being performed manually by a trained technician.

Our Hema-Tek 2000 staining machine provides consistently stained blood smears and slides on a variety of cytological preparations for microscope.

Biochemistry  

A Tokyo Boeki Prestige 24i random access biochemistry analyser is used to measure the proteins, substrates and enzymes that are present in the serum fraction of the blood. This provides the biochemistry parameters that are used by the vets to diagnose and monitor different clinical conditions.

Electrolytes are measured on an EX-D Jokoh and any out of hours emergency biochemistry can be easily performed by nurses or vets on a Vetscan analyser which is ideal for performing a rapid profile on an individual sample.

Tests and Profiles

Veterinary surgeons will either request individual tests or more usually profiles consisting of a number of tests appropriate to the species and/or problem being investigated. The exact combination of analysed elements will vary therefore from case to case, but the principle is that the tests will be tailor made to an individual, and will therefore be a cost effective part of the diagnosis.
