First Claim
Patent Images
1. A method for detecting sepsis in a human infant patient, said method comprising the steps of:
- (a) obtaining a blood sample from a human infant patient born to a mother having at least one infant sepsis risk factor, or a human infant patient displaying at least one sign of infection;
(b) contacting leukocytes in the blood sample with a labelled antibody which specifically binds a cell surface antigen of said leukocytes, wherein said cell surface antigen is selected from the group consisting of CD25, CD69, CD11c, CD33, and CD66b;
(c) determining the percentage of said leukocytes which bind said labelled antibody; and
(d) comparing the percentage of leukocytes which bind said labelled antibody to the percentage of leukocytes which bind said labelled antibody in a blood sample from a non-septic human infant age-matched to said human infant patient,wherein an increased percentage in the human infant patient compared to the non-septic human infant indicates sepsis in the human infant patient.
