HLA DSA-SAB CLASS I IgG ANTIBODIES WITH C1q SCREEN

THE HLA DSA-SAB CLASS I IGG ANTIBODIES WITH C1Q SCREEN IS A LABORATORY TEST USED TO IDENTIFY THE PRESENCE OF DONOR-SPECIFIC ANTIBODIES (DSA) IN THE BLOOD OF A POTENTIAL ORGAN TRANSPLANT RECIPIENT. THESE ANTIBODIES CAN CAUSE REJECTION OF THE TRANSPLANTED ORGAN. THE TEST SPECIFICALLY DETECTS ANTIBODIES THAT BIND TO CLASS I HLA ANTIGENS ON THE SURFACE OF DONOR CELLS AND CAN ACTIVATE THE COMPLEMENT SYSTEM, A PART OF THE BODYS IMMUNE DEFENSE. A POSITIVE RESULT FOR C1Q BINDING INDICATES THE PRESENCE OF ANTIBODIES THAT ARE MORE LIKELY TO CAUSE RAPID AND SEVERE REJECTION OF THE TRANSPLANTED ORGAN. THIS TEST IS ESSENTIAL FOR ASSESSING THE RISK OF TRANSPLANT REJECTION AND GUIDING THE SELECTION OF COMPATIBLE DONORS.
