Device Description and Intended Use
The Galileo is a microprocessor-controlled instrument designed to fully automate immunohematology in vitro diagnostic testing of human blood. The Galileo automates test processing, result interpretation and data management functions. The Galileo is designed to automate standard immunohematology assays using a microplate-based platform. Assays include ABO grouping and Rh (D) typing, detection/identification of IgG red blood cell antibodies, compatibility testing, red blood cell phenotyping and antigen screening, and infectious disease screening such as syphilis and cytomegalovirus (CMV).

This 510(k) summary applies to the addition of Immucor Anti-A,B (Murine Monoclonal Blend) Series 1 Blood Grouping Reagent for use in ABO assays on the Galileo. The Anti-A,B reagent is used for the detection of the A and B antigens on red blood cells.

All of the Galileo functions are fully automated, including: sample and reagent handling, pipetting, incubation, washing, shaking, centrifugation, reading and interpretation of results. Automated process controls and error detection mechanisms significantly reduce or eliminate opportunities for user error and invalidate suspect results.

Use of these assays does not require new sample handling or new instrument operational procedures. The Operator Manual has been revised to include information on the A,B assays.

The Galileo is a closed system intended for use only with the reagents specified in the Galileo Operator Manual.

Summary of Non-Clinical Tests

In-house testing was performed to evaluate equivalency of the Anti-A,B reaction results when tested on the Galileo with the Anti-A,B reaction results when tested by the reference method (manual tube). Equivalency was evaluated for both assay types that will use the reagent: Forward ABO testing and full ABO testing.

The results of the studies demonstrate that use of Immucor Anti-A,B (Murine Monoclonal Blend) Series 1 reagent on the Galileo will generate results equivalent to the established reference method. The agreement rate of the equivalency testing performed was above 99%.

Summary of Clinical Tests

Clinical testing of the ABO assays using FDA-licensed and 510(k)-cleared reagents was originally submitted and reviewed under BK040013. The results of the clinical testing supported the conclusion that the Galileo is safe and effective for the automated execution of ABO assays. The results of the clinical studies demonstrated that end users, with proper training, could use the Galileo to perform the in vitro diagnostic tests defined for Galileo and that the testing with specified reagents on the Galileo would generate results comparable to established reference methods.

In support of the current premarket notification additional Clinical testing was performed at an external facility to validate the use of Immucor Anti-A,B (Murine Monoclonal Blend) Series 1 on the Galileo in a user test site. Total data concordance was 100% between the Galileo ABORH_AB assay and the reference method manual tube testing Anti-A,B results and total data concordance was 99.6% between the Galileo FWDABO_AB assay and the reference method manual tube testing Anti-A,B results.

The non-clinical and clinical performance data demonstrates that the Galileo test results with AntiA,B (Murine Monoclonal Blend) Series 1 are substantially equivalent to manual tube reference method.
