Blood lab

QuestionAnswer
carrying capacity of blood depends upon: number of RBCs and amount of hemoglobin
how many heme groups are on each hemoglobin protein 4
how many oxygen molecules can each hemoglobin carry 4
too many RBCs polycythemia
hormone made by the kidney and released to increase RBCs erythropoietin
too many RBCs can do what increase blood viscosity and increase blood pressure
some athletes illegally take erythropoietin: why? and what are the risks? WHY- increases RBC - more ox- less tired RISK- heart attack, increased BP
insufficient # of RBCs or hemoglobin anemia
pernicious anemia is a type of macrocytic anemia
what causes pernicious anemia not enough RBC- deficiency in vitamin B12/infolic acid
what happens to RBCs in pernicious anemia RBCs are low but large in size
what type of anemia is known by not enough hemoglobin in RBCs causing them to be pale and small microcytic anemia
what often causes microcytic anemia iron deficiency (iron deficiency anemia)
describe carbon monoxide poisoning carbon monoxide has a higher affinity to bind to hemoglobin causes it to not diffuse as easily, decreases oxygen carrying capacity can result in death
describe neonatal jaundice all RBCs are replaced when a baby is born because babies have special hemoglobin needs to be replaced. Build up of waste product after destruction is billirubin.
normal RBC count in women 4 million -5.5 million
normal RBC count in men 4.5 million - 6 million
percentage of RBCs in blood hematocrit
normal hematocrit in women 42 +-5%
normal hematocrit in men 47+- 5%
normal hemoglobin in women 12-15 g/dl
normal hemoglobin in men 13-16 g/dl
MCV mean corpuscular volume
MCHC mean corpuscular hemoglobin concentration
what is the normal MCV range 82-92 mm3
what is the normal MCHC range 32-36%
MCV is size of RBC
MCHC is percentage of hemoglobin per RBC
how to find MCV hematocrit x 10/RBC count
how to find MCHC hemoglobin x 100/hematocrit
how to count RBC formula (1+2+3+4+5) x 10000
