The hemoglobin test is often used to check for anemia, usually along with a hematocrit or as part of a complete blood count (CBC) . The test may be used to screen for, diagnose, or monitor a number of conditions and diseases that affect red blood cells (RBCs) and/or the amount of hemoglobin in blood.he hemoglobin test is often used to check for anemia, usually along with a hematocrit or as part of a complete blood count (CBC) .

Volcanoes form at hot spots in the Earth's crust, at convergent plate boundaries where subduction of oceanic crust is occurring, and at divergent plate boundaries where gaps i â¦ n the crust are being infilled with rising magma.
Answer by Jake Weatherby. Confidence votes 83.5K. Hot spot volcanoes such as those in Hawaii and the Yellowstone Caldera form as a result of extra hot material rising from deep within the mantle. While most volcanoes can only form near plate boundaries, hot spot volcanoes can form in the middle of a tectonic plate.Unlike at subduction zones, which are generally associated with stratovolcanoes, hot spots that form under oceanic crust typically produce shield volcanoes.nswer by Jake Weatherby.
