There has been a great deal of interest in the media concerning the various different tests for the virus which until recently have only been available for those ill enough to be in hospital, and now for NHS staff. There is now a simple blood prick test to see whether you may have developed antibodies or not to the Coronavirus. Although this test may have a use, it is still under development and may not as yet be 100% reliable. It would therefore be preferable to wait for a full viral antibody profile which will be available in due course and would be done with a proper blood test sample and sent to the laboratory as normal.
The one piece of kit that might be useful is an Oxygen Saturation Meter, which is very useful in determining the overall function of the heart and lungs.
