Which disorder is indicated by the following test results: PLT 35 X 10^9/L, HGB 72 g/L, INR 1.5, and D-Dimer 22 mg/L?

The test results presented indicate a high D-Dimer level, low platelet count (thrombocytopenia), low hemoglobin level (anemia), and an elevated International Normalized Ratio (INR). These findings are indicative of disseminated intravascular coagulation (DIC).

In DIC, there is widespread activation of the coagulation cascade, leading to the formation of small blood clots throughout the small vessels in the body. This consumes clotting factors and platelets, resulting in the observed thrombocytopenia. The low hemoglobin level suggests that there may be ongoing bleeding or hemolysis, which can occur in DIC. The elevated INR reflects a disruption in the normal clotting process, as the coagulation factors are being depleted due to excessive clot formation. High D-Dimer levels are often found in DIC due to the breakdown of fibrin, which raises the level of fibrin degradation products in the circulation.

The combination of these laboratory findings strongly supports the diagnosis of disseminated intravascular coagulation, confirming its presence rather than the other options.
