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.
This civilization is known by many names: Ancient India, Indus Valley, and Harappan Civilization. Historians and archeologists believe the Indus Valley Civilization began around 3000 BCE. There is evidence of trade between Ancient India and Mesopotamia as early as 3200 BCE.
