Fournier gangrene laboratory tests

The most important laboratory findings in necrotizing fasciitis include C-reactive protein, total white blood cell count, Hemoglobin, Sodium, Creatinine, Glucose. The main importance of these laboratory findings are due to their usage as a distinguishing method for differentiating necrotizing fasciitis from other soft tissue infections.

The main importance of these laboratory findings are due to their usage as a distinguishing method for differentiating necrotizing fasciitis from other soft tissue infections. Laboratory findings consistent with the diagnosis of Fournier gangrene include:

• CBC with differential count
• Culture of open wound or abscess
• Disseminated intravascular coagulation panel

• Coagulation studies(PT, aPTT, thrombin time etc)
• Fibrinogen/fibrin degradation product levels

• Blood culture
• Urine culture
• Arterial blood gas analysis
• Electrolyte panel
• Blood urea nitrogen (BUN)
• Creatinine
• Blood glucose levels

Laboratory risk indicator for necrotizing fasciitis (LRINEC) scoring system

LRINEC is a diagnostic scoring system used to distinguish necrotizing fasciitis from other soft tissue infections.^[1][2] It was first established by Wong et al in 2004.

• Score of ≤5 indicates low risk
• Score of 6-7 indicates intermediate risk
• Score of ≥8 indicates high risk
