19
Q

RAM

A

random access memory; temporary storage of data in CPU

20
Q

ROM

A

read-only memory; contains instruction for operation ofcomputer installed by manufacturer

21
Q

software

A

coded instructions required to control hardware inprocessing of data

22
Q

storage

A

a place for keeping data; outside computer, it is calledsecondary storage

23
Q

verify

A

to confirm or check for correctness of input

24
Q

computer networks

A

– A group of computers linked for purpose of sharing resources
– Offers advantage
– Individual computer stations are called nodes
– Include simple interoffice connections & complex systems between several organizations in different cities (Internet)
– Speed up processing, increase productivity, & reduce cost

25
Q

Three Basic Components of Computer Systems

A

Input (order)
Process (running of specimen)
Output (result)

26
Q

Three Elements that make up a computer system

A

Hardware
Software
Storage

27
Q

LIS objectives

A
  • File results
  • Accumulate statistics to determine workload
  • Generate report forms
  • Monitor quality assurance & quality control in lab
28
Q

LIS advantages

A
  • Improved accuracy in testing
  • Reduced clerical & billing errors
  • Flexible delivery options for reports
  • Increased efficiency
29
Q

What is the system manager responsible for (LIS)?

A
  • Training personnel & updating them on software changes
  • Solving day-to-day problems that develop after system is installed
30
Q

Four major components of LIS

A

– ID code
– Password
– Icons & mnemonic codes
– Bar codes

31
Q

Radio frequency ID

A
  • Composed of a reader & a tag or label
  • Tag is applied to product or person to identify & track using radio waves
  • Wireless scanner can track more than one tag at a time
  • Used to monitor patients and identify & track specimens, equipment, & records
32
Q

computerized analyzers

A

Sophisticated computer systems designed to manage patient data and to interface w. the LIS & main hospital intranet

33
Q

Connectivity Industry Consortium (CIC)

A

Established to ensure that any POC analyzer can talk to any LIS

34
Q

Computerization Trends

A

– Decentralization & increased POC testing
– Increase in remote lab testing facilities networks

35
Q

Specimen handling

A

preanalytical phase
routine handling or special handling
specimen suitability
centrifugation

36
Q

Routine handling

A

– Mixing tubes by inversion
– Transporting specimens
– Delivery time limits

37
Q

Special handling

A

– Body temperature specimens
– Chilled specimens
– Light-sensitive specimens

38
Q

specimen processing

A
  • Identified
  • Logged/accessioned
  • Sorted by department & type of processing required
  • Evaluated for suitability for testing
39
Q

Specimens are rejected for

A
  • Hemolysis
  • Insufficient amount of specimen (QNS)
  • Clotting
  • Inadequate, inaccurate, or missing specimen ID
  • Wrong or outdated tube
  • Improper handling
  • Wrong collection time
  • Exposure to light
  • Delay in testing
  • Delay or error in processing
40
Q

centrifuge

A

a machine that spins blood tubes at high rpm
Force separates cells and plasma or serum

41
Q

Removing a stopper

A

Face or splash shield
gauze or tissue to cover stopped
pull stopper straight up and off

42
Q

aliquot

A

portion of specimen used for testing.
used when multiple tests are ordered or when tests are performed on different instruments or in different areas.
Prepared by transferring a portion of specimen into one or more tubes labeled
