Patent ID: 8030006

Claim:
A blood testing method to confirm the detection of a disease in a subject, wherein the disease is characterised by the presence of at least one characteristic antibody/complement factor bound to the surface of the red blood cells of the subject, comprising the steps of: providing a microarray wherein a plurality of binding agents which are capable of binding specifically to different characteristic antibodies or compliment factors on the red blood cells are immobilised on a substrate at discrete predefined positions; contacting a blood sample from the subject with said microarray; substantially removing any unbound red blood cells from at least an area of said substrate on which said binding agents are immobilised; and detecting the presence or red blood cells bound to the microarray through said characteristic antibodies or complement factors, wherein the presence of any red blood cells bound to the microarray indicates the presence of said characteristic antibody/complement factor bound to the red blood cells of the subject so as to confirm detection of said disease.
