Abstract
The peak value of the first derivative of the optical density time curve is related to individual clotting factor levels, deficient or elevated. The relationship is logarithmic for all factors except fibrinogen and it is linear for fibrinogen. The apparatus and process disclosed herein apply the relationship to determine blood clotting factor levels.
