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.
Lastly, Dr. Ansell reminded us that the predictive value of the d-Dimer test also varies with the test that is used. The latex test is less sensitive such that a normal latex d-Dimer test rules out a new clot with about a 90% certainty. With the more sensitive enzyme-linked (ELISA) test, a normal test rules out a new clot with a 95% to 99% certainty.
