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.
Among the 2898 patients with a nonhigh or an unlikely clinical probability, 817 patients (28.2%) had a D-dimer level lower than 500 Âµg/L (95% CI, 26.6%-29.9%) and 337 patients (11.6%) had a D-dimer between 500 Âµg/L and their age-adjusted cutoff (95% CI, 10.5%-12.9%).
