Six samples were assayed in one FX kit run in replicates of 10 using a microplate. The samples were two controls (one normal and one prolonged), two patient samples with normal levels, and two patients with prolonged levels.

Precision Data

FX Concentration (%)	CV Within Run
Normal (98 – 107%)	1.9 – 12.0%
Abnormal (23 – 32%)	4.7 – 19.6%

The central tendency for within-run precision of the DiaPharma Factor X kit is approximately 7 %CV.
