1. A device for the detection of an analyte in an ocular fluid sample comprising:
- a lateral flow chromatographic test strip comprising;
a sample application zone;
a detection zone located downstream of the sample application zone;
a conjugate zone located upstream of the detection zone, wherein the conjugate zone comprises at least one labeled binding partner able to migrate with an elution medium;
a housing containing the lateral flow chromatographic test strip and having a sample application window and a read out window; and
a swab member comprising a swab member body having a body opening and a sample collection material extending from the swab member body for collecting the ocular fluid sample;
wherein the lateral flow chromatographic test strip, the housing, and the swab member are formed such that when the lateral flow test strip is contained in the housing and the sample collection material is inserted through the sample application window, the body opening of the swab member body corresponds to the read out window, and the sample collection material is in fluid communication with the sample application zone to transfer the ocular fluid sample from the swab member to the sample application zone;
wherein the at least one labeled binding partner comprises a conjugate of gold particles and an anti-Hexon antibody; and
wherein, when the analyte is present in the ocular fluid sample, the labeled binding partner complexes with the analyte and then migrates to the detection zone.

13. A device for the detection of an analyte in an ocular fluid sample comprising:
-
a lateral flow chromatographic test strip comprising; a sample application zone; a detection zone located downstream of the sample application zone; and a conjugate zone located upstream of the detection zone, wherein the conjugate zone comprises at least one labeled binding partner able to migrate with an elution medium; a housing containing the lateral flow chromatographic test strip; and a swab member comprising a plastic swab member body having a body opening which corresponds to the read out window and a sample collection material extending from the swab member body for collecting the ocular fluid sample, wherein the sample collection material is fixed to the swab member body by ultrasonic welding; wherein the sample collection material and the sample application zone are selected to provide fluid communication between the sample collection material and the sample application zone to transfer the ocular fluid sample from the swab member to the sample application zone without dilution; wherein the at least one labeled binding partner comprises a conjugate of gold particles and an anti-Hexon antibody; and wherein, when the analyte is present in the ocular fluid sample, the labeled binding partner complexes with the analyte and then migrates to the detection zone. - View Dependent Claims (14, 15, 18, 19)
