|
(RBC)
|
Red blood cell count
number of red cells x 10^12 / L norm- 4.2-6.02 |
|
|
(Hb or Hgb)
|
Hemoglobin
measures concentration of Hb in gms/deciliter 11.5-16 |
|
|
(Hct or crit)
|
Hematocrit
volume of RBCs expressed as % of whole blood. 37-47 |
|
|
(MCV)
|
Mean corpuscular volume
(Hct) / (RBC) in femtoliters 1fl= 10^-15 L 81-99 |
|
|
(MCH)
|
Mean corpuscular hemoglobin (Hb)/(RBC) in picograms (pq)
26-30 |
|
|
(Retic)
|
Reticulocyte count % of young cells
reticulocytes are larger and more spherical , still make Hgb with mRNA, cytoplasm stains Hgb light blue - polychromasia 1-2% |
|
|
(RDW)
|
Red cell distribution width
statistical value describing distribution of MCV standard deviation MCV/MCV 12.1-14.6 |
|
|
Segs
|
segmented neutrophils
|
|
|
Corrected reticulocyte count
|
retic adjusted for Hct
Retic x Hct/ ideal Hct |
|
|
(RPI)
|
Reticulocyte production index
corrects for early release of retics = corrected retic x .5 increased value indicates good bone marrow function. |
|
|
decrease production anemias
|
Fe, B12, Folate, Low thyroid, renal insufficiency, chronic disease, bleeding, myelodysplastic syndrome, Marrow inflitration 1*2, aplastic anemia.
|
|
|
MCV < 80fl
|
microcytic anemia
ex. Fe deficiency, Thalassemia, Sideroblastic anemia (alcohol, lead, B6 def, drugs, myelodysplasia) |
|
|
MCV 80-100
|
normocytic anemia
w/ elevated retic- bleeding, hemolysis Normal retic- chronic (renal), meds suprressing marrow, mixed ( ie B12 and Fe def) |
|
|
MCV > 100
|
Macrocytic anemia
Megaloblastic- B12, folate def, meds, orotic aciduria, Lesch-Nyhan. Non- Megablastic Increased retic (bleeding/hemolysis) Norm/Low retic (liver disease, alcoholism, hypothyroid, MDS, Spurious) |
