🗑
|
||||
| Maintenance of quality across all aspects of the testing process | show 🗑
|
||||
| show | to evaluate the system and prevent errors
🗑
|
||||
| show | Pre-analytical because there's less automation for this and we see an increase with human error

🗑
|
||||
| why liquid QC over lyophilized | show 🗑
|
||||
| analyzed by the manufacturer so the concentration of the analyses they contain is known | show 🗑
|
||||
| concentration of the analyses is unknown and must be determined by the lab | show 🗑
|
||||
| show | maintenance is done, something is suspected to be wrong, reagent lot change, major component replacement
🗑
|
||||
| A sudden change due to an analyzer malfunction | show 🗑
|
||||
| a gradual change due to reagent deterioration | show 🗑
|
||||
| show | rerun once, ask questions, contact service technician if problem is not resolved
🗑
|
||||
| concentration of a substance is proportional to the amount of light absorbed | show 🗑
|
||||
| measures the intensity of light at selected wavelength | show 🗑
|
||||

🗑
|
||||
| show | scavenger layer
🗑
|
||||
| show | reagent layer
🗑
|
||||
| reacted sample collects for spectral analysis | show 🗑
|
||||
| show | support
🗑
|
||||
| measures the absorption of light by an element in its ground state | show 🗑
|
||||
| show | determining blood lead levels
🗑
|
||||
| Valence electrons from some substances are able to absorb light energy, exciting the electron, electron returns to ground state and gives up energy as a photon of light which results in a fluorescence emission | show 🗑
|
||||
| show | fluorochromes/fluorophores
🗑
|
||||
| commonly used fluorescent dye in the lab | show 🗑
|
||||
| two ways light scatter is measured | show 🗑
|
||||
| show | nephelometry because more light is scattered than transmitted
🗑
|
||||
| show | turbidimetry
🗑
|
||||
| test done by turbidimetry | show 🗑
|
||||
| the measurement of scattered light by a particulate solution | show 🗑
|
||||
| lab test performed by nephelometry | show 🗑
|
||||
| impedance-based technology that is used to analyze cells | show 🗑
|
||||
| Four main component of a flow cell cytometer | show 🗑
|
||||
| show | hydrodynamic focusing
🗑
|
||||
| show | lenses collect light and focus it on a photodiode and the light is converted to electrical current; measures cell size
🗑
|
||||
| show | uses wavelength-specific mirrors and filters to transmit light specific to the wavelength of the dye that is used; measures cell complexity
🗑
|
||||
| lab test performed by flow cytometry | show 🗑
|
||||
| show | scintillation counter
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
