Patient X was discovered to be a platelet clumper when using EDTA
anticoagulant. A repeat platelet count was performed on a 3.2% buffered
sodium citrate (blue top) evacuated tube with a 4.5 mL draw. The corrected
platelet count should be multiplied by a factor of
a. 1.1.
b. 3.2.
c. 4.5.
d. 1.406. - ✔️
✔a️. 1.1.
Critically low platelet counts are called to the doctor/nurse when the count is
a. below 20 x 10<sup>9</sup>/L.
b. above 120<sup>10</sup>/L.
c. between 150-400 x 1,000/μL.
d. between 150-400 x 10<sup>11</sup>/μL. - ✔️
✔️a. below 20 x
10<sup>9</sup>/L
A slightly hazy body fluid is submitted for a manual cell count. It is diluted
1:100. All nine squares are counted on the hemocytometer, totaling 101
leukocytes. The reported leukocyte count should be
a. 11.2 x 10<sup>9</sup>/L.
, b. 1.12 x 10<sup>9</sup>/L.
c. 112 x 10<sup>6</sup>/L.
d. 11.2 x 10<sup>6</sup>/L. - ✔️
✔️a. 11.2 x 10<sup>9</sup>/L.
If one is doing an electrophoresis of hemoglobin and is using cellulose
acetate at an alkaline pH of 8.6, permitting the flow of electrons from the
cathode to the anode, which hemoglobin migrates the fastest to the anode?
a. HbA
b. HbS
c. HbC
d. HbD - ✔️
✔a️. HbA
What is the difference between polymerase chain reaction (PCR) and reverse
transcriptase PCR (rtPCR)?
a. Following amplification, PCR generates a DNA product and rtPCR
generates a RNA product.
b. Substrate used for rtPCR is RNA instead of DNA.
c. Deoxyribonucleotides is added to the reaction mixture of PCR versus
ribonucleotides added to the rtPCR reaction mixture.
d. None of the above. - ✔️
✔️b. Substrate used for rtPCR is RNA instead of
DNA.
On blood films prepared with Wright's stain, what is/are abnormally early
released of the RBCs from the marrow into the peripheral blood and is
indicated by the presence of nucleated RBCs or polychromatophilic
macrocytes on blood films prepared with Wright's stain?
a. Shift cells
