An increase in IGs of >2% can be a useful in identification of acute infection. Published studies have shown high specificity of IG count for infectious diseases but low sensitivity, precluding the use of such a count as a screening test for sepsis.
Three types of convergent boundaries are recognized: continentâcontinent, oceanâcontinent, and oceanâocean. Continentâcontinent convergence results when two continents collide. The continents were separated at one time by oceanic crust that was progressively subducted under one of the continents.
Transform boundaries, where plates slide alongside each other. A subduction zone is something that happens only with convergent boundaries. Subduction is where, after colliding, one plate sinks below the other. And a subduction zone is the area where two plates are sandwiched on top of each other, like a tectonic BLT. Features & Location of Subduction Zones. Subduction zones are places of high activity.
