<H3>Special Instructions</H3>
 Only PDQ Patient Demographics Supplier (PDS) and Patient Demographics Consumer (PDC) actors which support the <i>Patient Demographics & Visit Query option</i> will run this test.
 
 <h3>Description</h3>
 This tests the interaction between the PDS and PDC actors for the QBP^ZV1 query and RSP^ZV2 response messages.
 <p>
 Patient demographics fields for query (from the PID segment) are tested in the PIX_CLIENT test.  The visit fields (from the PV1 segment) are tested in this test.  PDS and PDC actors may support one or more of the fields listed in the Evaluation section; neither actor is required to support all.  PDS and PDC partners need to speak to each other to discover which fields are supported in common.  (It may be difficult to find partners to exercise all of the fields your application supports.)</p>
 <p>Once common fields are discovered, ensure that the PDS contains records that will show that the query results distinguish between different patient records.</p>
 <H3>Evaluation</H3>
 Verify that the <b>Patient Demographics Supplier</b> is able to issue queries based on filters specified by the Patient Demographics Consumer in the fields listed below.  
 <p>Verify that the <b>Patient Demographics Supplier</b> supports responding to queries based on filters specified by the Patient Demographics Consumer in the following fields.  
 </p>
 <p>

 <ul>
 <li>PV1.2 - Patient Class</li>
