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.
The lines where they meet are called plate boundaries. There are three main types of plate boundary: divergent, convergent and transform. Plates move away from one another at divergent boundaries. This happens at mid-ocean ridges.Plates move towards one another at convergent boundaries; one plate is forced below another in a process called subduction.Earthquakes and composite volcanoes are common at this type of boundary. Plates move past on another at transform boundaries.The most famous example of this type of boundary is the San Andreas Fault in California.
