Agent detection and/or quantitation in a biological fluid
View Patent ↗A method of assessing retinal disease in an eye of a patient by rapid, point of care, quantitative detection of cytokine levels is provided.
1. A method of rapidly diagnosing retinal disease by quantitative detection of cytokine levels in an eye of a patient, comprising:
(a) contacting ocular anterior chamber fluid from a patient with a detection reagent that detects a clinically relevant concentration of a single cytokine in the ocular anterior chamber fluid by generating an output as a result of an interaction between the single cytokine in the ocular anterior chamber fluid and the detection reagent,
(b) assessing the output of the detection reagent, and
(c) diagnosing the presence of a retinal disease based on the output of the detection reagent,
wherein quantitative detection of the clinically relevant concentration in the ocular anterior chamber fluid of the patient results in rapid diagnosis of a retinal disease.
2. The method of claim 1 wherein the clinically relevant concentration of the cytokine is about 120 pg/ml to about 400 pg/ml, and indicates the presence of retinal disease.
3. The method of claim 1 wherein the single cytokine is vascular endothelial growth factor (VEGF).
4. A method of rapidly diagnosing retinal disease by quantitative detection of cytokine levels in an eye of a patient, comprising:
(a) contacting ocular anterior chamber fluid from a patient with a detection reagent that detects a clinically relevant concentration of a cytokine in the ocular anterior chamber fluid by generating an output as a result of an interaction between the cytokine in the ocular anterior chamber fluid and the detection reagent,
(b) assessing the output of the detection reagent, and
(c) diagnosing the presence of a retinal disease based on the output of the detection reagent,
wherein quantitative detection of the clinically relevant concentration in the ocular anterior chamber fluid of the patient results in rapid diagnosis of a retinal disease, and wherein the detection of a clinically relevant concentration of a single cytokine results in rapid diagnosis of a retinal disease.
5. The method of claim 4 wherein the clinically relevant concentration of the cytokine is about 120 pg/ml to about 400 pg/ml, and indicates the presence of retinal disease.
6. The method of claim 4 wherein the single cytokine is vascular endothelial growth factor (VEGF).
