- 1, 2, and 3 are correct
- 1 and 3 are correct
- 2 and 4 are correct
- only 4 is correct
- all are correct
- Which of the following is a/are general characteristic(s) of discrete multichannel analyzers?
- each specimen is added into a separate compartment along with the reagents
- the absorbance of the reaction mixture is read at a steady-state plateau
- carryover between samples is minimized
- all of the tests done by the analyzer are performed on each specimen
- For random access analyzers, it is true that:
- all of the available tests done by the analyzer are performed on each specimen
- reagent and sample volumes are dependent upon the inner diameter of pump tubing
- the integrity of individual samples is maintained through the segmentation of the sample stream with air bubbles
- the analyses that are performed for a sample are only the ones that were ordered
- The dry—chemical reagent technique has the following features:
- the dry reagent is impregnated on a solid phase
- can be prepared by most laboratories using common reagents
- the measuring reaction begins when sample comes in contact with reagent
- usually cheaper than techniques
- using bulk reagents
- An instrument has 17 reagents available for analysis and can perform 3 tests at a time. The immediate test repertoire of this instrument is:
- 3
- 14
- 17
- 20
- 51
- Stat. Instruments should have high test throughput:
- true
- false
- An instrument can process 40 samples an hour and perform 6 tests on each sample simultaneously. The test throughput of this analyzer is:
- 6
- 40
- 46
- 240
- 280
- Which of the following is not usually considered to be a function of an automated analyzer?
- computation
- proportioning of reagent

Use the following Key to answer Questions 8 through 11:
- 1, 2, and 3 are correct
- 1 and 3 are correct
- 2 and 4 are correct
- only 4 is correct
- all are correct
- Automated Front-End specimen processing includes:
- specimen identification
- specimen sorting
- specimen decapping
- specimen aliquoting
- The goals of laboratory automation are:
- to reduce cost
- to decrease laboratory testing
- to reduce laboratory errors
- to increase workstations
- The major drawbacks of Total Laboratory Automation are:
- Substantial financial investment
- Inability to sort and decap specimens
- Limited availability of laboratory space
- Lack of clot and aliquot capabilities
- In some laboratories, manual Front-End Specimen Processing accounts for:
- Is needed for workstation consolidation
- 60% of the testing cost
- Is required for archiving of specimens
- Is responsible for most of the lost specimens
- Autoverification of laboratory results is the automated reporting of selected test results without verification by the technologist or laboratory supervisor.
- True
- False
- Archiving and retrieval of specimens is a time consuming process that can be automated using stand-alone systems.
