MCHC and MCV, or mean corpuscular volume, levels are both used to test a person for anemia. MCHC tests for the levels of hemoglobin in the blood. This test is also referred to as an MCH test.
Civilization first developed in the Indus River valley in present-day Pakistan in the middle of the 3d millennium B.C., more than a thousand years earlier than it did in China. In fact, the civilization of the Indus valley, usually called Harappan after its chief city, rivals Sumer and Egypt as humanity's oldest. But like Sumer and its successor civilizations in the Middle East, Harappan civilization was unable to survive natural catastrophes and nomadic invasions.
The Indus Valley, or Harrapan, civilization was a Bronze Age culture spanning roughly 3300â1700 BCE. The level of civilization was comparable to Mesopotamia and Ancient Egypt. Although the original names are unknown, the two main city sites are known as Harrapa (after a nearby modern town) and Mohenjo-Daro (Hill Of The Dead.)
