Interfacing Types.

 

  1. Uni-directional Devices 

 

Uni-directional device interfaces normally allow the lab technician to enter patient identifying information (e.g., Medical Record Number (MRN, Name, Date of Birth and sex) using the device data entry function. The device will include this information when it transmits to the Apex LIS when the test is completed. When the LIS receives the patient identifying data it will the data to match the results against an existing order. 

 

 

 

  1. Bi-directional Devices 

A Host Query interface is like a bi-directional interface with the addition that with a Host Query interface the analyzer can request information from the LIS (i.e., AU480). This is a more efficient system because the instrument reads the barcode on the specimen and "queries" the LIS for the test orders. The LIS will be listening on a communication port for queries and will download the requests only when needed. In cases where the LIS transmits data such as test orders or control messages to analyzers the communication is set up to be bi-directional.

Why Lab Equipment Interfacing important.

Lab Information System Laboratory Information System (LIS) allows you to effectively manage the flow of samples and patient data to improve lab efficiency. It improves access to quality diagnostic testing and provides accurate, timely information for patient care. Raster LIS helps in standardizing workflows, tests, and procedures while providing accurate controls of the process. Laboratory equipment (both unidirectional and bi-directional) may be integrated via Raster IoMT with Raster LIS to automate the collection of test data, ensuring they are properly calibrated. The fully integrated configuration tools help in adapting the software to end-user requirements without compromising on support or future upgrades. A key attribute of Raster LIS is the avoidance of platform dependencies. interfacing LIMS to your lab instruments removes many complexities like manual entering of data every time or referring data from other instruments to the LIMS. This altogether saves a lot of time and effo...
