Introduction

Laboratory Information System (LIS) refers to the subsystems that support the capability
to program patient samples and test requests remotely on the analyzer, to transfer data
regarding the patient and physician demographics, assay quality control data, and to
query the laboratory computer system for test requests. The LIS includes
VITROS

®
5,1 FS Chemistry System software, the laboratory computer system, and the

hardware that connects the two systems.

LIS Functions

Provides a method to receive remotely programmed patient and quality control
sample programs (test requests) from a lab computer (download from lab
computer)

Provides a method to send patient results and quality control results to a lab
computer (upload results to lab computer)

Provides the ability to request sample programs from a lab computer in order to
process sample (host query)

Provides indication to the operator the status of communication between the
analyzer and the lab computer (status)

o The LIS status: Idle, Upload, and download.
o The Query status is: True, False.

Provide the ability to process requests for onboard inventory levels (inventory
query)

Provide a method to send analyzer status information to another system (error
messages/automation status updates)

LIS Communications Protocol

The communications protocol used on the VITROS 5,1 FS Chemistry System was
created by the American Society for Testing and Materials (ASTM). It is designed
specifically for medical devices and supports the transfer of an array of medical data. It
enables speedy communication while using a number of data protection mechanisms,
such as, acknowledgments, timing mechanism, and data recovery procedures. It also
establishes a national standard for communication among medical facilities and may
eventually become an international standard. The ASTM protocol promotes data
integrity while handling a great volume of data.
Information about this protocol can be found in a publication produced by ASTM: Annual
Book of ASTM Standards. Designation: E 1394-97: “Standard Specification for
Transferring Information Between Clinical Laboratory Instruments and Computer
Systems” and Designation: 1381-95: “Specification for Low Level Protocol to Transfer
Messages Between Clinical Laboratory Instruments and Computer Systems.” It is
recommended that these publications be obtained and used as supplements to this
guide.

Operational Overview

Communication occurs over the serial lines from the analyzer to the lab computer using
the ASTM protocol. The communications are bi-directional and include: downloading of
sample programs from the lab computer to the analyzer, uploading of result records
from the analyzer to the lab computer, and querying of sample programs from the
analyzer to the lab computer.

Download Sample Programs

Sample programs (containing specimen ID, patient information, and tests to be
run) are entered into the lab computer

The lab computer initiates communication to the analyzer
The analyzer acknowledges requests for communication
The lab computer transfers the sample program and patient information to the

analyzer
