Sepsis Screen

What is Sepsis screen test?

The Sepsis screen test is a diagnostic blood test used to help detect early signs of sepsis, a life-threatening condition caused by the body’s extreme response to an infection. It typically involves biomarker detection (such as Procalcitonin, C-reactive protein (CRP), Interleukins, or Gene Expression Signatures) to identify systemic infection and the inflammatory response and to evaluate sepsis risk or severity early—often before traditional blood cultures are positive.

Why consider Sepsis screen test?

Sepsis screen test can be considered for

• Early detection of sepsis: Sepsis can progress rapidly and is often fatal if not treated promptly.
• Faster than blood cultures: Provides results in hours rather than days.
• Guides early treatment decisions: Helps determine whether antibiotics, antivirals, or supportive care are needed.
• Supports risk stratification: Identifies patients at higher risk of poor outcomes.
• Reduces unnecessary antibiotics: Can help differentiate between bacterial and viral causes of systemic inflammation.

Who should get tested for Sepsis screen test?

Sepsis screen test is typically used for:

• Hospitalized patients with suspected infection and systemic symptoms
• ICU patients showing signs of sepsis or septic shock
• Emergency room patients with high fever, low blood pressure, or altered mental status
• Patients with known or suspected bacterial infections who are deteriorating rapidly
• Immunocompromised individuals at high risk of bloodstream infections
• Neonates or elderly patients with nonspecific symptoms but high risk for sepsis

Sepsis is a life-threatening medical emergency that happens when the body has an extreme response to an infection. Instead of fighting just the infection, the immune system causes widespread inflammation that can lead to organ failure and death if not treated quickly. Common Causes of Sepsis are bacterial infections (most common), viral infections and fungal infections. Early identification is critical — the risk of death increases significantly with every hour that treatment is delayed.
