Consistently High Quality Serum for Analysis


Low Residual Fibrinogen Concentration

  • minimises risk of re-clotting

Minimal Presence of Cells

  • minimises changes to key analytes over time

Low Haemoglobin

  • indicates high clot strength

Stability of analytes in serum when stored for 7 days

  • allows accurate re-testing if required
