How does a Quantitative buffy coat analyzer work? Simple |
|
Definition
-Uses measurements from an expanded buffy coat. - Stains agran.'s green and gran's orange/yellow -Can only do a simple diff. -Gives agran and gran %'s only |

Advantages to a buffy coat analyzers? |
|
Definition
-easy to operate -compact size of the machine -low maintenance -minimum consumables to track -service is relatively inexpensive |
|
|
Term
Disadvantages to a buffy coat analyzers? |
|
Definition
-Requires live specimens -highest cost per test -slow turn around time - 10mins -No quality control -limited diagnostic application |
|

Term
How does the impedance method/coulter counter principle work? Simple |
|
Definition
-cells are passed through an opening containing electrical current created by two electrodes. Each cell that passes through the electrodes creates an interruption/impedance which is measured by the machine. The machine is set to measure within a certain threshold/range. |
