At FDX, we specifically work with venous blood draw that has been centrifuged to ensure the biomarkers are safeguarded and to maintain complete accuracy within our complex and comprehensive reports.

Centrifugation is a method of separating solids from liquids using rotational forces (spun). When blood is centrifuged the red cell portion and plasma is separated. Leaving the delicate biomarkers stable and intact, and suitable for transportation to the lab. Without centrifuging, many of the biomarkers become unstable and deteriorate over time, which can result in incorrect results. For this reason, we cannot offer finger prick testing for our larger sophisticated FDX panels.
