Using SQL Server 2008:

I have this query :

Select       
      Distinct TR.Serial_Number,      
    CASE
      WHEN (TR.Test_Result LIKE '%PASS%') THEN  'Pass'
      ELSE ''      
      END   as 'DecayResults',
      MAX(TR.Date_Time)  as 'DecayDate'      
FROM
      dbo.Test_Results TR  
WHERE       
      (TR.Date_Time BETWEEN '2013-12-18 00:03:44.890' AND '2013-12-20 00:03:44.890')  
      AND (ISNULL(TR.Serial_Number,'')<>'') AND LEN(TR.Serial_Number) > = 14
      AND (TR.System_ID LIKE '%Decay%')
Group By
      TR.Serial_Number,TR.Test_Result
      

I am getting the results below:
SerialNumber                    DecayResults      DecayDate

I want to eliminate duplicate serial numbers from my above query....

Also I want to keep 'Pass' records and eliminate records without 'Pass' for the same SerialNumber....


Any Idea?
