Theorem: In a triangle ABC, three lines AD, BE and CF intersect at a single point K if and only if . Proof of Concurrency of the Three Medians . Now using Ceva's theorem, it will be straightforward to prove that the three medians intersect at one point.
D-dimer normal range. The normal range for D-dimer is approximately 0.5 mg/l of blood or 500 mg/ml of blood.Testing of d-dimer range is usually not done when suspicions of individuals who have symptoms of scattered intra-vascular coagulation have been confirmed and have been diagnosed to be suffering from the condition. blood test is used to determine the concentration of D-dimer in the blood. Thrombosis is a condition that affects the ability of the blood to form clots and a D-dimer test is done to diagnose the presence of the condition.
1 A low or normal d-dimer test result means that there is very little of the substance that's released as a blood clot breaks up. 2  Having very little of this substance means that a blood clotting problem isn't likely. 3  A higher-than-normal d-dimer level might mean that there is a blood-clotting problem.
