An elevated D-dimer level is not normal. It is usually found after a clot has formed and is in the process of breaking down. If you are having significant formation and breakdown of blood clot in your body, your D-dimer may be elevated. A negative D-dimer test means that a blood clot is highly unlikely.

An alginate impression is used in dentistry to make an exact replica of the patientâs teeth, gingiva, and surrounding tissues in the mouth. The alginate dental impression forms an imprint (i.e. a ânegativeâ mould) of those teeth and gums, which can then be used to make a cast or âpositiveâ model of the patientâs dentition. Alginate impression material begins as a powder. When mixed with water, a thick pasty material, similar to cake frosting, appears.
