title: Clinical significance of ischemia modified albumin in critically ill patients with sepsis.
abstract: The study was conducted on 38 patients admitted into the intensive care unit with a provisional diagnosis of sepsis and 25 apparently healthy volunteers as controls. Serum procalcitonin (PCT) was assayed by an electrochemiluminescence method. Serum ischemia modified albumin (IMA), expressed as absorbance units was assayed by the albumin cobalt binding test. Patients with sepsis had significantly higher IMA levels (1.087 ± 0.786) as compared with those without sepsis (0.085 ± 0.234) with a p value <0.0001. The receiver operator characteristic (ROC) plot showed a sensitivity of 100 % and a specificity of 86.2 %. The area under the curve of the ROC plot was 0.917 with a p value of <0.0001. The higher levels of IMA serve to highlight the occurrence of ischemic damage which could be a prelude to poorer prognosis. The performance characteristics of IMA warrants its inclusion along with PCT as a parameter in the diagnosis of sepsis.
