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.
Where the plates meet, their relative motion determines the type of boundary: convergent, divergent, or transform. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along these plate boundaries.The lateral relative movement of the plates typically ranges from zero to 100 mm annually. Convergent boundaries (Destructive) (or active margins) occur where two plates slide toward each other to form either a subduction zone (one plate moving underneath the other) or a continental collision.
