RATED A+
what falsely decreases ESR ✔✔low blood/ room temps, air
bubbles, tests <1 hr, improper mixing of blood, improper dilution
lactic acid collection ✔✔separate from serum and put on ice
coefficient of variation ✔✔(standard deviation/ mean) X 100
Carbon dioxide electrode measures what ✔✔Used to measure
free carbon dioxide ions by detecting pH. The change in pH is
measured by an internal pH sensor, which is proportional to the
carbon dioxide level.
patient that had a random glucose >200 and an FPG >126. What

Picture of target cells with hemoglobin C crystals. The white
count was high on instrument 1, so
