a count of the number of RBC in a given volume of blood

Question 15

hemoglobin (HGB or Hgb)

Answer 15

a test to determine the blood level of Hgb expressed in grams

Question 16

hematocrit (HCT or Hct)

Answer 16

a measurement of the percentage of packed RBC in a given volume of blood

Question 17

blood indices

Answer 17

calculations of RBC, HGB, and HCT results to determine the average size, hemoglobin concentration, and content of RBC to classify an anemia

Question 18

mean corpuscular (cell) volume (MCV)

Answer 18

calculation of the volume of individual RBCs using HCT and RBC results
MCV = HCT/RBC

Question 19

mean corpuscular (cell) hemoglobin (MCH)

Answer 19

calculation of the content of Hgb in the average RBCs using HGB and RBC results
MCH=HGB/RBC

mean corpuscular (cell) hemoglobin concentration (MCHC)

Answer 20

calculation of the average Hgb concentration in each RBCs using HGB and HCT results
MCHC = HGB/HCT
