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.
The Test. A red blood cell (RBC) count is typically ordered as part of a complete blood count (CBC) and may be used as part of a health checkup to screen for a variety of conditions.n RBC count is ordered as a part of the complete blood count (CBC) , often as part of a routine physical or as part of a pre-surgical workup. When someone has signs and symptoms suggesting a disease that might affect red blood cell production, a CBC that includes the RBC count may help make a diagnosis.
