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.
The age-adjusted cutoff was particularly useful in elderly patients (age â¥ 75 years). Of the 673 such patients with a low/intermediate or unlikely clinical probability, only 43 had a D-dimer < 500 Âµg/L. An additional 157 had a D-dimer concentration between 500 Âµg/L and their age-adjusted cutoff.
