Abstract

  

Objective: D- dimer test is used as a diagnosis test for acute disseminated intravascular coagulation (DIC).This study was undertaken to evaluate the sensitivity and specificity of D- dimer test in the diagnosis of acute DIC and its role in diagnosis of sub- clinical DIC.

Material and Method: A total of 18 patients of clinically diagnosed as acute DIC and 13 patients with sub- clinical DIC were included in the study.

Result: All the patients had positive D- dimer test, and markedly prolonged PT, aPTT and TT were seen in 14 (77.78%) patients. D- dimer test was found to be highly specific but less sensitive for the diagnosis of acute DIC. Out of 13 patients predisposed to sub - clinical DIC D-dimer was positive is 02 (15.38%) patients and PT, aPTT and TT were mildly prolonged in 02(15.38%) patients.

Conclusion: It is suggested that D-dimer positivity for the diagnoses of sub- clinical DIC need to be considered with caution and to be supplemented by other coagulation test including serial follow up with d- dimer and coagulation tests.

Keywords: D-dimer, sub -clinical DIC, acute DIC.
