Macrocytic RBCs are large so tend to have a higher MCH, while microcytic red cells would have a lower value.. MCH is one of three red blood cell indices (MCHC and MCV are the other two). The measurements are done by machine and can help with diagnosis of medical problems.

Map showing the location of Pavlof Volcano near the end of the Alaska Peninsula. The boundary between the North American Plate and the Pacific Plate is shown by the gray toothed line.The Pacific Plate is to the south of the boundary, and the North American plate is to the north of this boundary. The A-B line shows the location of the cross section below.avlof eruptions often produce pyroclastic flows. These are hot clouds of rock, gas and ash that sweep down the flanks of the volcano at speeds of up to 100 miles per hour. They are dense enough to knock down trees and hot enough to incinerate everything in their path. Lava flows are produced by many Pavlof eruptions.
