Lateral flow immunoassay for complement activation and methods of use for point-of-care assessment of complement-associated disorders

摘要

A method for treating an individual at risk for a complement-associated disorder is provided, including: (a) obtaining a sample of a body fluid from the individual; (b) measuring a complement activation level in the sample via a point-of-care lateral flow immunoassay; (c) correlating the complement activation level in the sample to a risk of a complement-associated disorder by comparing the complement activation level in the sample to a reference level in a control, wherein a deviation in complement activation level in the sample compared to the reference level in the control indicates the individual is at risk for a complement-associated disorder; (d) selecting a treatment for the individual, based on the correlating of step (c); and (e) treating the individual with the treatment selected in accordance with step (d). Lateral flow immunoassays and a method of monitoring an individual suffering from a complement-associated disorder are also provided herein.

主权项

1. A lateral flow immunoassay for the point-of-care detection of a marker of complement activation in a body fluid sample comprising complement proteins, the lateral flow immunoassay comprising:
a membrane strip; a detecting antibody that binds a first epitope of the marker; a test line comprising a capturing antibody that binds a second epitope of the marker; and a control line comprising an antibody that binds a control analyte,wherein the marker is iC3b.
