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 common points where the plates touch one another is where the earthquake starts or the focus. As seen in the picture above, subduction zones are on the borders of each tectonic plate. As they crash together one plate moves below the other which causes subduction zone earthquakes. Earthquakes are one of the biggest natural disasters known to man. Earthquakes occur when there is a sudden release of energy below the earths crust at the focus.
