New blood marker could help doctors catch sepsis days sooner
NCT ID NCT07232784
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study looked at whether measuring a protein called PSP in the blood can help doctors recognize sepsis earlier in ICU patients at high risk. Researchers enrolled 250 adults in China, taking daily blood samples until sepsis was diagnosed or ruled out. The goal was to see if PSP levels could predict sepsis up to three days before standard diagnosis, potentially leading to faster treatment and better outcomes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Pancreatic stone protein (PSP) blood test
- What this could lead to
- If successful, this could give doctors a new tool to diagnose sepsis days earlier, allowing quicker treatment and potentially saving lives.
- What could go wrong
- This is an observational study, not a treatment trial. The test may not prove accurate enough in real-world settings, and results from 250 patients in China may not apply to all ICU populations.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. ICU patients over 18 years old; 2. Patients at high risk of sepsis in any of the following: 1. History of recent surgery or invasive medical procedures; 2. Pneumonia, complicated urinary tract infections, abdominal infections, central nervous system infections, etc.; 3. Severe trauma: such as the percentage of total body surface area (TBSA) burned \> 15%, or serious traffic accident injuries, etc.; 3. Expected ICU stay for more than 4 days; 4. Have provided written informed consent or consent is given by the patient's legally designated representative. Exclusion Criteria: 1. Patients diagnosed with sepsis; 2. Patients expected to die within 48 hours of admission to ICU; 3. Pregnancy; 4. Patient suffering from or known acute or chronic pancreatitis, pancreatic cancer or admitted after pancreatectomy; but if a patient develops any pancreatic disease during the ICU stay, he/she will remain in the study; 5. Patients with SOFA score \< 2 but who have undergone blood purification; 6. Unable or unwilling to provide the required blood sample for testing; 7. Patients with unclear medical record information; 8. Patients with mental disorders and other disorders who cannot correctly understand informed consent; 9. Patients who subjectively refused to be enrolled in the study or who were judged not to be enrolled by the investigator.
