Answer

Most individual laboratory tests demonstrate high sensitivity for DIC but very low specificity. [54] Furthermore, whereas acute DIC typically overwhelms compensatory anticoagulation mechanisms, resulting in depletion of factors and laboratory derangements, chronic or localized DIC may produce only minimal abnormalities in laboratory tests. [55]

It is essential to keep in mind that laboratory values may represent only a momentary glimpse into a very rapidly changing systemic process and that repeated tests may therefore be necessary in order to make a more clinically certain diagnosis. [4]
