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.
This test may be used to determine if further testing is necessary to help diagnose diseases and conditions that cause hypercoagulability, a tendency to clot inappropriately. A D-dimer level may be used to help diagnose disseminated intravascular coagulation (DIC) and to monitor the effectiveness of DIC treatment.-dimer tests are used to help rule out the presence of an inappropriate blood clot (thrombus). Some of the conditions that the D-dimer test is used to help rule out include: 1  Deep vein thrombosis (DVT).
