Analytical Validation of the abioSCOPE Device With an IgE Test Panel: Point-of-Care Precision, Sample Type Comparison and Method Correlation

Abionic SA

Overview

This is a multicenter, prospective, observational study to evaluate the analytical performance of the Abionic IgE Multi-Allergen Test Panel on the abioSCOPE® device in a U.S. point-of-care environment within a clinical laboratory operating under a CLIA certificate for tests of moderate complexity. The study will assess point-of-care ('external') precision, sample type comparison and correlation with a reference method (Phadia Laboratory System, ThermoFisher Scientific).

Outcomes

Primary Outcomes

POC variance components (in a POL environment):

* External Precision Study ('reproducibility study' 'site-to-site precision study'): Demonstrate that the imprecision of K3-EDTA venous plasma using the IVD CAPSULE Allergic Asthma panel on the abioSCOPE device (all 5 allergens/allergen mixes and total IgE) in the hands of trained Healthcare Professionals in a Physician Office Laboratory (POL) is within the expected range of the imprecision established in the clinical laboratory by Laboratory Scientists. * Operator-to-Operator imprecision on whole blood: Demonstrate that the between-Operator reproducibility of the total IgE of the IVD CAPSULE Allergic Asthma panel on the abioSCOPE device test results is within the expected range of variability. * Between-run reproducibility: Demonstrate that the between-run reproducibility of venous whole blood samples measured with the IVD CAPSULE Allergic Asthma panel on the abioSCOPE device (all 5 allergens/allergen mixes and total IgE) is within the expected range of variability.

Time frame: Day 1

Sample type comparison:

Demonstrate that the IVD CAPSULE Allergic Asthma panel on the abioSCOPE device test results obtained from capillary whole blood correlates well with values obtained from K3-EDTA anticoagulated venous plasma and serum samples.

Time frame: Day 1

Method comparison

Demonstrate that test results obtained with the total IgE test of the IVD CAPSULE Allergic Asthma panel on the abioSCOPE device correlates with total IgE test results from the reference method (Phadia Laboratory System, ThermoFisher Scientific).

Time frame: Day 1
