Question

Which of the following statements regarding automated hematology analyzers is not true?

1) Special stains can be used to differentiate various cell populations.
2) Hematology analyzers use light scatter, impedance technology, and various staining methods to count and evaluate cells.
3) Results are generally accurate, reproducible, and ready in a short period of time.
4) Instrument settings for the size of each cell type are universal to all species.

Answer 1

Automated hematology analyzers use various methods to count and evaluate cells. Special stains can differentiate cell populations, but instrument settings are not universal for all species.

Step-by-step explanation:

Automated hematology analyzers are used to count and evaluate cells in blood samples.

They use light scatter, impedance technology, and staining methods to differentiate different cell populations.

Special stains can indeed be used to differentiate various cell populations, which contradicts statement 1.

Results obtained from hematology analyzers are generally accurate, reproducible, and ready in a short period of time, which supports statement 3.

However, instrument settings for the size of each cell type are not universal to all species.

Different animal species may require different instrument settings to accurately measure and classify their cells, so statement 4 is not true.
