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.
Colliding Plates. Convergent boundary, divergent boundary and transform boundary are the three types of boundaries that form due to plate tectonic movement. Converging plates usually form subduction zones.Subduction zones ring the Pacific Plate causing frequent earthquakes, volcanic eruptions, and tsunamis.hen the two plates meet the oceanic crustal plate always subducts beneath the continental plate. The subducting oceanic plate bends and plunges beneath the lighter continental plate until it melts. When two oceanic plates meet and form a subduction zone the heavier and denser of two oceanic plates subducts.
