Abionic SA has developed a novel point-of-care (POC) platform, the abioSCOPE, and an in vitro diagnostic kit for the quantification of the pancreatic stone protein (PSP) to be analyzed specifically with the abioSCOPE® device. This test is intended to be used to aid in the early recognition of sepsis. The test is extremely easy to use and has a total turnaround time of approximately 8 minutes. This test uses only 30 microliters of K2/K3-EDTA anticoagulated whole blood or plasma. Results are quantitative (ng/ml). The product is for Investigational Use Only in the US and bears CE-marking. It is commercially available in selected European and non-European countries. The test has also been clinically validated in a multicentric, prospective, observational study performed (AB-PSP-001, clinicaltrials.gov identifier NCT03474809). The main goals of this study are to evaluate certain analytical performances components of this product in a point-of-care environment, in particular the precision, sample type comparability and specimen stability of the product. Such data will support regulatory filing of a US FDA 510(k) premarket notification file and of a European IVD Regulation technical file to continue product commercialization in 2022, when this novel regulation will be effective.

The blood samples for the study for each patient will be collected in the form of additional tubes. * either 1 tube of blood of 4 ml and 2 tubes of blood of 10 ml once a day for 1 or 2 days maximum (or 48 ml maximum) during his hospitalization * either 2 tubes of 10 ml or 20 ml maximum once during his hospitalization.

Precision variance components
coefficient of variation, expressed in percent, for the different variance components, are determined
Time frame: Day 1
Sample type comparison
pairwise comparability of test results when performed with K2-EDTA anticoagulated venous whole blood or K2-EDTA anticoagulated venous plasma, represented as percent recovery of whole blood compared to plasma, as well as scatter plots with Weighted Deming and Passing Bablok Regression, and bias plots.
Time frame: Day 1
Sample stability
Scatter plot and bias plot of PSP values versus storage time or freeze and thaw cycles, as well linear least square regression analysis
Time frame: Day 1
