After Alexanderâs death his Empire was divided among his four generals (known in Latin as the Diadochi, the name by which they are still referenced, from the Greek, Diadokhoi, meaning successors): Lysimachus, Cassander, Ptolemy and Seleucus.
It is generally recognized that POCT is more expensive on a unit cost basis than central laboratory testing. In the case of the Biosite D-dimer, the unit cost, including reagents, labor, quality control, and calibration, is approximately $23.92 per test. The VIDAS D-dimer cost is approximately $20.92 per test, including labor, supplies, and specimen processing.
D-dimer is normally undetectable in the blood and is produced only after a clot has formed and is in the process of being broken down. When there is significant formation and break down of blood clots in the body, the D-dimer blood level can rise. The D-dimer test measures the level in the blood. For a person who is at low or intermediate risk for thrombosis and/or thrombotic embolism, the strength of the D-dimer test is in its negative predictive value in a hospital emergency room setting. That means that a negative D-dimer test indicates that it is highly unlikely that a thrombus is present.
