P17054: OCD Blood Analyzer


Project Summary Project Information

Our senior design project involves redesigning the universal sample tray used in Ortho Clinical Diagnostics’ clinical blood sample analyzers. Analytical tests like the Hemoglobin A1c (HbA1c) diabetes test require whole blood samples rather than serum or plasma samples. When a whole blood sample is left undisturbed, sedimentation of red blood cells or the settlement of the cells toward the bottom of the sample container occurs. The current universal sample tray design requires blood analyzer operators to manually suspend the cells, mixing the blood samples shortly before the sample is analyzed.

The goal of our project is to develop a sample suspension tray design that will keep the red blood cells in whole blood samples suspended, therefore eliminating the need for manual interference. Our expected end result will be a working prototype that interfaces mechanically with the existing clinical blood analyzers and keeps the red blood cells suspended for a sampling period of at least 30 minutes.
