Question

1. Parameters measured in the use of flow cytometry for the diagnosis of hematologic malignancies include all of the following except A. Forward angle light scatter B. Right angle light scatter C. Bound antibody surface fluorescence D. None of the above 2. Forward angle light scatter is proportional to A.Cell size B. Nuclear/cytoplasmic complexity C. Both 3. The purpose of the fluidics channel is used to: A. Allow detector measurement of scatter B. Allows cells to pass through laser one cell at a time C. Allows Fluorophores to emit light D. All of the above 4. The purpose of optics are to: A. Convert signals to usable data B. To sense the light C. To gather the light 5. The purpose of detectors are to: A. Convert signals to usable data B. To sense the light C. To gather the light

Answer 1

1, d, None of the above
Flow cytometry is a fast and reliable method for phenotyping tissue sample it detects easily infrequent hematological malignancies.
2, a, Cell size
Forward scatter signal intensive is proportional to cell size. It allows for the discrimination of cells by size.
3, b, Allows cells to pass through laser one cell at a time
Fluidics in technology that flows a cell by sensing volumes to obtain a serial analysis of particles one at a time basis.
4, a, Convert signal to usable data
In data processing, geometrical optics have image-forming properties of the mirror, the lens of the devices that make use of light.
5, b, To sense the light
Photodetectors are called photosensors(sensors of light). The photon detector is the human eye that detects visible light with a wave length.
