Dielectric blood coagulometry is a newly emerging approach for the assessment of the hemostatic potential of blood using the electronic technique of dielectric spectroscopy. Since the aggregation and deformation of red blood cells (RBCs) - two critical processes underlying blood coagulation - play a pivotal role in this approach, it is essential to characterize such measurements at reduced hematocrits for applications that involve anemic blood samples. To that end, we develop a protocol for creating reconstituted whole blood (rWB) samples with diminished hematocrits as low as ~10%. These samples are next evaluated using our microfluidic dielectric coagulometer - termed ClotChip - as well as rotational thromboelastometry (ROTEM), which is the clinical standard for viscoelastic coagulometry. We find that rWB samples with hematocrits as low as~10%still exhibit a characteristic dispersion region at MHz frequencies that is attributed to the interfacial polarization of RBC membranes. Furthermore, we show that the two ClotChip readout parameters indicative of clotting time and clot firmness correlate well with those measured by ROTEM for rWB samples with hematocrits in the range of ~10-40 % . This work illustrates the viability of ClotChip as a dielectric blood coagulometer to assess hemostatic function at hematocrits as low as ~10 % .
