Abstract: A method of measuring the amount of TNF-related apoptosis-inducing ligand (TRAIL) polypeptide in a fluid sample of a subject in need thereof is disclosed. The method uses a lateral flow immunoassay (LFI) device.

Abstract: A method of determining a management course for treating a subject showing symptoms of a disease is disclosed. The method comprises measuring the TRAIL protein level in a blood sample of the subject, wherein when the TRAIL level is below a predetermined amount, the subject is treated as a high-risk patient.

Abstract: A method of measuring risk assessment in a patient is disclosed. The method comprises: (a) measuring the TRAIL protein level in a blood sample of the patient; (b) measuring the level of at least one disease-associated parameter in the patient; and (c) providing a risk assessment based on the combination of said TRAIL protein level and said disease-associated parameter level.

Abstract: Methods of determining infection type are disclosed. In one embodiment, the method comprises measuring the amount of TRAIL and/or IP10 no more than two days from symptom onset.

Abstract: A method of analyzing biological data containing expression values of a plurality of polypeptides in the blood of a subject. The method comprises: calculating a distance between a segment of a curved line and an axis defined by a direction, the distance being calculated at a point over the curved line defined by a coordinate along the direction. The method further comprises correlating the distance to the presence of, absence of, or likelihood that the subject has, a bacterial infection. The coordinate is defined by a combination of the expression values, wherein at least 90% of the segment is between a lower bound line and an upper bound line.

Abstract: A method of analyzing biological data is disclosed. The method comprises obtaining biological data containing at least an expression level of MX dynamin-like GTPase 1 (MX1) and an expression level of C-reactive protein (CRP) in the blood of a subject, calculating a distance between a segment of a curved line and an axis defined by a direction, the distance being calculated at a point over the curved line defined by a coordinate along the direction, and correlating the distance to the presence of, absence of, or likelihood that the subject has, a bacterial infection.

Abstract: Methods of determining infection type are disclosed. In one embodiment, the method comprises measuring the amount of a determinant which is set forth in Tables 1 or 2 in a sample derived from the subject, wherein said amount is indicative of the infection type.

Abstract: Methods of diagnosing infections are disclosed. In one embodiment, the method comprises measuring the amount of each of the polypeptides TRAIL, CRP, IP10 and at least one additional polypeptide selected from the group consisting of IL-6 and PCT.

Abstract: A method of selecting an exon of an RNA whose expression level is informative with respect to infection type of a subject is disclosed. The method comprises comparing the expression level of the RNA in a sample derived from a bacterially-infected subject and a sample derived from a virally-infected subject at a plurality of exons, wherein the exon that provides a differential expression between the bacterially-infected subject and the virally-infected subject above a predetermined level is selected as the exon of the RNA whose expression is informative with respect to infection type.

Abstract: A method of determining an infection type in a subject is disclosed. The method comprises measuring the concentration of a first determinant selected from the group consisting of the determinants which are set forth in Table 1 and a second determinant selected from the group of the determinants which are set forth in Table 2 in a subject derived sample, wherein the concentration is indicative of the infection type.
