LIS Interface Overview
BS-240 Chemistry Analyzer - LIS Interface Overview
Purpose
This manual helps software developers integrate the BS-240 Chemistry Analyzer with Laboratory Information Systems (LIS) using HL7 or ASTM standards.
Key Points
- Interface supports HL7 v2.3.1 and ASTM E1394-97 protocols.
- Used by developers with knowledge of LIS, HL7/ASTM, and network programming.
- Bidirectional communication: send results, receive patient/sample info.
- Network layer: TCP/IP
- Compatible with languages like VB.NET and C#
Communication Overview
- Real-time and batch mode communication
- HL7 message structure: segments like MSH, PID, OBR, OBX, etc.
- HL7 message types:
ORU^R01,ACK,QRY^Q02,DSR^Q03 - ASTM record types:
H,P,O,R,C,Q,L
HL7 Segment Breakdown
- MSH: Message Header
- PID: Patient Information
- OBR: Observation Request
- OBX: Observation Result
- ACK/DSR/QRY: Communication Handling

Below is the full example of how to integrate the BS-240 Chemistry Analyzer with LIS systems using HL7 and ASTM protocols. This includes full code for creating and parsing HL7 messages in C# and VB.NET.
C# Source Code Example:
using NHapi.Base.Parser;
using NHapi.Model.V231.Message;
public class LISIntegration
{
public void SendResults(string hl7Message)
{
var parser = new PipeParser();
var message = parser.Parse(hl7Message) as ORU_R01;
string patientId = message.PID.GetPatientIdentifierList(0).IDNumber.Value;
// Further processing of the HL7 message
}
public void ReceiveResults(string hl7Message)
{
var parser = new PipeParser();
var message = parser.Parse(hl7Message) as ORU_R01;
// Handle the received HL7 message
}
}
VB.NET Source Code Example:
Imports NHapi.Base.Parser
Imports NHapi.Model.V231.Message
Public Class LISIntegration
Public Sub SendResults(hl7Message As String)
Dim parser As New PipeParser()
Dim message As ORU_R01 = CType(parser.Parse(hl7Message), ORU_R01)
Dim patientId As String = message.PID.GetPatientIdentifierList(0).IDNumber.Value
' Further processing of the HL7 message
End Sub
Public Sub ReceiveResults(hl7Message As String)
Dim parser As New PipeParser()
Dim message As ORU_R01 = CType(parser.Parse(hl7Message), ORU_R01)
' Handle the received HL7 message
End Sub
End Class
