Overview: Sepsis 30 Real Time PCR TestIntroduction: The Sepsis 30 Real Time PCR Test detects bacterial DNA to diagnose sepsis, causing fever or organ failure. Aligned with 2023 IDSA guidelines, it uses real-time PCR for high specificity, supporting infection screening. This test is critical for guiding diagnosis, treatment planning, and improving outcomes in bacteriology for patients with suspected sepsis.
Other Names: Sepsis PCR Assay, Bacterial DNA Sepsis Test.
FDA Status: Laboratory-developed test (LDT), meeting bacteriology standards for diagnostic accuracy.
Historical Milestone: Sepsis PCR testing began in the 2000s with molecular diagnostics. Real-time PCR methods improved in the 2010s, enhancing diagnostic precision.
Purpose: Detects bacterial DNA to diagnose sepsis, guides treatment, and evaluates patients with fever or organ failure.
Test Parameters: 1. Bacterial DNA Detection
Pretest Condition: No fasting required. Collect whole blood, plasma, CSF, or saliva. Report history of fever, organ failure, or sepsis symptoms.
Specimen: Whole Blood (EDTA, 2-5 mL), Plasma (EDTA, 2-4 mL), CSF (sterile container, 1-2 mL), Saliva (sterile container, 1-2 mL). Transport in a biohazard container.
Sample Stability at Room Temperature: 24 hours
Sample Stability at Refrigeration: 48 hours
Sample Stability at Frozen: Not frozen
Medical History: Document fever, organ failure, or history of infections. Include current medications, especially antibiotics.
Consent: Written consent required, detailing the tests purpose, sepsis implications, and risks of sample collection.
Procedural Considerations: Uses real-time PCR to detect bacterial DNA from multiple pathogens. Results are available in 3-5 days, supporting clinical decisions. Performed in laboratories, often for sepsis diagnosis.
Factors Affecting Result Accuracy: Low DNA yield or contamination can affect results. Antibiotic use may reduce sensitivity.
Clinical Significance: Positive bacterial DNA confirms sepsis, guiding antibiotic therapy. Negative results may require blood cultures.
Specialist Consultation: Consult an infectious disease specialist or critical care physician for result interpretation and treatment planning.
Additional Supporting Tests: Blood cultures, procalcitonin, or lactate levels to confirm sepsis diagnosis.
Test Limitations: Limited to targeted pathogens; clinical correlation is needed. Sample quality affects sensitivity.
