MEDICAL DEVICE, IMMUNOASSAY METHOD AND TEST FOR DETECTING PROLIFERATIVE DIABETIC RETINOPATHY

The present invention relates to a medical device (1) comprising three pathways (3, 4, 5), wherein each pathway is extending between a first zone (6) intended to receive a sample in the liquid form and an end zone (7) having an absorbent portion, wherein each pathway comprises the following zones, all extending between the first zone and the end zone: a catch zone (8) loaded with a predetermined amount of a predetermined protein, wherein the protein is constituted by TNF-alpha, Lactoferrin and Lipocalin-1, respectively; a conjugate zone (9) arranged upstream of the catch zone, loaded with a respective antibody bounded to an indicator means, wherein the antibody is specific for the TNF-alpha, Lactoferrin and Lipocalin-1 proteins, respectively; and a control zone (10) arranged downstream of the catch zone, loaded with an anti-immunoglobulin species-specific antibody, the invention relates also to an immunoassay method and test of the TNF-alpha, Lipocalin-1 and Lactoferrin proteins for detecting proliferative diabetic retinopathy in a patient.
