Preparing a blood sample

Use the dedicated Lorrca reagents (see Appendix - Parts list)

A blood sample can be stored at a maximum of one hour (at room temperature). After that the sample cannot be used anymore.

1. Bring the blood sample to room temperature.
2. For the highest precision perform a cell count and see chapter RBC necessary per test/scan for the required whole blood volume.
   Just before the measurement, mix the calculated sample volume (as a reference 250 μl of normal EDTA-anticoagulated blood) in the 5 ml ready to use Elon ISO.
3. Gently mix the blood by inverting the tube 40 times (don’t shake) until it is homogeneous.
