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.
There are 3 types of plate boundaries-convergent, divergent, and transform. Convergent boundaries occur when 2 plates collide with each other and push each other. Neither plate will give way, so the crust on the plates rise up and form mountains and mountain ranges. Divergent boundaries form rift valleys, volcanoes, and deep-ocean trenches, and transform boundaries cause earthquakes. Plates slide, collide and shift.
