Already I wrote how to send an ORM file to Quest lab. Please refer this link – Quest and Mirth – 1
Now I am going to write here how to get/receive a result file (ORU) from Quest Lab.

You may have a different requirements, but as per my need I have created 2 channels for just getting the result and processing them within our system

1. 1st Channel Name : Quest-Results Import
2. Configuration Source:     
   Connector Type : JavaScript Reader
We need to define a timeline to trigger the java script code. Based on this pulling mechanism, your mirth request will be triggered to hit the Quest server for getting the result from them. Coz as I belive, once you send an order to Quest lab, they are not going to convey you that when did they upload the result. Hence we need to automate the process.

In javascript editor box write any valid java script code otherwise leaving it blank will throw you an error. like var app = “Quest”;

3. Configuration Destination:    
Connector Type : SOAP Sender
WSDL Path: https://<UserName>:<Password>@cert.hub.care360.com:443/resultsHub/observations/hl7?wsdl
Service Endpoint URI : https://<UserName>:<Password>@cert.hub.care360.com:443/resultsHub/observations/hl7
Send Response To : Quest Result WS  [This is your 2nd Channle – why? – You will come to know]
User Persistence QueueS : No
Method : GetHL7Results
Now you need to fill up the parameters to above method carefully under “Method” block in Mirth

> Click on string endDate – right side under value fill null
> int maxMessages = 1
> startDate = null
> rest you can leave them blank

Using above method you will get the result from Quest which will be sent to the 2nd channel. But Quest sends you an encoded ORU file (not the plain HL7 ORU file). Hence our target is to decode it and get the right HL7 ORU file.

4. 2nd Channel Name : Quest-Results-WS-Decoder
5. Configuration Source: channel reader ( from 1st channel )
Use the tranformation as below:

//This transformer reads the encoded result message, decodes it, convert it into string and writes to a file.
var qstORUmsg = new XML(msg);
//var qstORUmsgSize = qstORUmsg.*::Body.*::getHL7ResultsResponse.*::result.*::HL7Messages.*.length().toString();
var qstORUmsgSize = qstORUmsg.*::Body.*::getHL7ResultsResponse.*::result.*::HL7Messages.*::HL7Message.length().toString();

//channelMap.put('qstORUmsgSize',qstORUmsgSize);
var encoded = "", decoded = "", finalMsg = "", msgfileId  = "";
for(var i=0; i < qstORUmsgSize; i++){
 encoded = qstORUmsg.*::Body.*::getHL7ResultsResponse.*::result.*::HL7Messages.*::HL7Message[i].*::['message'].toString();
 decoded = FileUtil.decode(encoded);
 finalMsg = Packages.java.lang.String(decoded);
 msgfileId = UUIDGenerator.getUUID();//DateUtil.getCurrentDate("hhmmss.SSS");
 FileUtil.write('C:/MedLink_IX/Quest/Results_Test/Decoded/'+msgfileId+'.hl7', false, finalMsg); 
}

This will be writing each HL7 ORU message into a file with unique name.

5. Message template to be used

Outbound Message Template:
Keep a valide HL7 message of ORU type. [MSH, PID, PV1 …..]
6. Configuration Destination:  
Channel Writer (Dummy destination for WS Decoder) – as you already got the file using FileUtil.write
