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.
What is the d-Dimer test? This question has both a simple and a complex answer. The simple answer is that the d-Dimer test is a blood test used to rule out active blood clot formation. If you have a negative (normal) d-Dimer result, that nearly rules out the possibility that you have a blood clot actively forming.
