Blood metal ion analysis
For patients who have already undergone joint replacement surgery, we use inductively coupled plasma mass spectrometry (ICP-MS) to measure the level of cobalt and chromium in the bloodstream. It is widely accepted a level of 7 micrograms per litre indicates an increased risk of an adverse reaction.
However, our research has shown that a significant number of patients may develop destructive tissue lesions at concentrations as low as 2 micrograms per litre.
Orthotype incorporates blood metal ion testing and high resolution genotyping to help identify the patients at greatest risk of adverse tissue responses.
As there can be a significant time delay in the appearance of inflammation following surgery, an Orthotype test report will also provide the clinician with a time-dependent risk profile.
