Question 1

In the Technicon H1, leukocyte analysis involves staining with peroxidase in a heated chamber with lysis of platelets and __________.

Accepted Answer

In the Technicon H1 leukocyte analysis, staining with peroxidase in a heated chamber involves the lysis of platelets and red blood cells (RBCs), allowing for the differentiation and counting of white blood cells (WBCs).

Question 2

In the Technicon H1, cells are counted as they pass in front of a laser beam by a __________ detector.

Accepted Answer

The Technicon H1 counts cells using a laser beam and a light scatter detector. As cells pass in front of the laser beam, they scatter the light, and this scatter is detected by the photodetector. Therefore, the correct choice is light scatter. Choices A, B, D and E are not involved in cell counting using the Technicon H1.

Question 3

Enumeration and identification of blood cells by the Technicon H1 automated blood analyzer is based on optical __________.

Accepted Answer

The Technicon H1 automated blood analyzer uses a combination of optical methods for enumeration and identification of blood cells, including flow cytometry, cytochemistry, and light scatter. These techniques allow for the detailed analysis and differentiation of various blood cell types based on their physical and chemical properties.

Question 4

The Technicon H1 instrument identifies and grades (1+ to 4+) various RBC abnormalities including:

Accepted Answer

The Technicon H1 instrument identifies and grades various RBC abnormalities including microcytosis, macrocytosis, hypochromia, and hyperchromia. Therefore, the best choice is E (all of the above).

Question 5

In Technicon H1 technology, red cells and platelets are counted based on their __________ properties.

Accepted Answer

Technicon H1 technology uses light scattering to count red cells and platelets.
