Hydrogen is a chemical element with chemical symbol H and atomic number 1. With an atomic weight of 7000100794000000000â 1.00794 u, hydrogen is the lightest element on the periodic table.Its monatomic form (H) is the most abundant chemical substance in the universe, constituting roughly 75% of all baryonic mass. Non-remnant stars are mainly composed of hydrogen in its plasma state.ritium (hydrogen-3), produced in nuclear reactors, is used in the production of hydrogen bombs, as an isotopic label in the biosciences, and as a radiation source in luminous paints. The triple point temperature of equilibrium hydrogen is a defining fixed point on the ITS-90 temperature scale at 13.8033 kelvins.
What Abnormal Results Mean. If the RBC is low or any of the RBC indices are abnormal, some form of anemia is indicated. If the values are high, it is a condition called polycythemia. It is necessary to consider all these values to get the right diagnosis.
When MCV values are normal, the red blood cells are normal in size. They are called normocytic. However, a person with normocytic red blood cells can still be anemic when there are too few red blood cells or when other RBC indices are abnormal. This is called normocytic anemia.
