In septic shock, which lab result should be reported immediately?

• A. Elevated fibrin split products or D-dimer
• B. High WBC count
• C. Low platelets
• D. Low lactate

Answer: (A)

In septic shock, a dangerous coagulation disorder can develop called disseminated intravascular coagulation. Reporting elevated fibrin split products or D-dimer right away is crucial because it signals active widespread coagulation with simultaneous breakdown of clots throughout the body. This pattern means the patient is at high risk for both clotting complications and severe bleeding, and it requires urgent evaluation and management to prevent rapid deterioration. This lab finding is a particularly strong cue for DIC because D-dimer rises when clots are being formed and then degraded, reflecting the ongoing, system-wide process. Recognizing this early helps clinicians escalate care promptly—confirming coagulation studies, guiding transfusion decisions, and addressing the underlying infection. While a high white blood cell count indicates infection, it doesn’t convey the immediacy of a coagulation catastrophe. Low platelets can occur with DIC but may follow the initial signal detected by elevated D-dimer. A low lactate is not alarming in this context (high lactate signals hypoperfusion, not a problem with lactate being low).
