HemaSpot-SE Blood Separation Device

Serum Collection at Your Fingertips

What is HemaSpot-SE?

HemaSpot-SE is an easy to use blood sampling device that provides a consistent, uniform and rapid separation of serum/plasma from a single finger stick.

HemaSpot-SE is the uniquely designed device that allows for the separation of whole blood into its constituent parts of whole blood cells and serum.  HemaSpot-SE separates serum from whole blood by impeding the movement of larger particles such as whole cells while allowing serum soluble components to flow freely through the form.  Red blood cells, platelets and leukocytes are found concentrated in the center of the form while serum and serum components are found in the spiral arm away from the red blood cells (Figure 1).

Sample Analysis

Samples punched (positions A, B, C, D; Fig. 1) from blood separated and dried on HemaSpot-SE show high DNA levels only at position A (Fig. 2).  RNA is found in both cell (A, B) and non-cell (C, D) positions (Fig. 3).  The small molecule, Nifedipine, shows similar levels for all positions (Fig. 4).
