  • Red blood cell count (RBC) or erythrocyte count - the total number of red blood cells in the sample. 
  • Hematocrit (HCT) - the percentage of the sample that was made of RBC.
  • Hemoglobin (HGB) - the volume of the protein hemoglobin in the RBCs. 
  • Mean corpuscular volume (MCV) - the average volume of the RBC.
  • Mean corpuscular hemoglobin (MCH) - the average amount of hemoglobin in the RBC.
  • Mean corpuscular hemoglobin concentration (MCHC) - the average concentration of hemoglobin in the RBC.
  • Red cell distribution width (RDW) - an indication of the size of the RBCs.
  • Platelet count - the total number of platelets in the sample.
  • Mean platelet volume (MPV) - an indication of the size of the platelets.
