,components of a CBC WBCs, RBCs, PLTs, Hgb, Hct
leukopenia decreased WBCs
leukocytosis increased WBCs, indicates infection
thrombocytopenia decreased PLTs, indicates bleeding
thrombocytosis increased PLTs
lipid panel components total cholesterol, triglycerides, LDL, HDL
arterial blood gas (ABG) components pH, PaCO2, HCO3, PaO2, SaO2
kidney lab components BUN, Creatinine, urinary output, specific gravity
coagulation lab components aPTT, INR
blood transfusion reaction signs - dyspnea, rales, pulmonary edema
- tachycardia, hypotension, jugular vein distention (JVD)
- fever
- flank pain
- pruritus
- dermatitis
hemoglobin measures gas-carrying capacity of RBC
hematocrit measures packed cell volume of RBCs, expressed as percentage of total blood
volume
platelet count number of circulating platelets
total RBC count number of circulating RBCs per volume of blood
, Red cell indices MCV, MCH, MCHC
mean corpuscular volume (MCV) determines relative size of RBCs (80-95 fL)
low MCV reflect microcytosis
high MCV reflects macrocytosis
mean corpuscular hemoglobin (MCH) measures average weight of Hgb/RBCs (27-31 pg)
low MCH indicates microcytosis or hypochromia
high MCH indicates macrocytosis
mean corpuscular hemoglobin concentration (MCHC) evaluates RBC saturation with Hgb (32-36%)
low MCHC indicates hypochromia
high MCHC indicates spherocytosis
RBC morphology examines shape and size of RBCs
reticulocyte count number of immature RBCs released from the bone marrow into the blood (0.5-2% of
RBC)
WBC differential determines whether each kind of RBC is present in proper proportion. determines
absolute value of each type of WBC my multiplying the percentage of cell type by
total WBC count and dividing by 10
T/F: segmented neutrophils are more mature than banded true
neutrophils
activated clotting time (ACT) evalutes intrinsic coagulation status. more accurate than aPTT. used during dialysis,
coronary artery bypass procedure, arteriograms (70-120 seconds)
