    3 Version 2 of the pathology import of data into i2b2 is based on the mapping of the top 100 Blood Sciences and Microbiology tests ordered from GGH Cardio Locations.
     3Version 2 of the pathology import of data into i2b2 is based on the mapping of the top 100 Blood Sciences and Microbiology tests ordered from GGH Cardio Locations.  The test have been mapped to [http://www.connectingforhealth.nhs.uk/systemsandservices/data/uktc/snomed Snomed CT] codes and [http://loinc.org/ LOINC] codes to see which best serves our requirements.

     7The Snomed CT mapping was carried out using the [http://www.snoflake.co.uk Snoflake] and [http://www.snomedbrowser.com/ NPEx] Snomed search engines.

     9It was not always possible to find Snomed CT codes for the exact finding associated with the test.  In these instances a code for the procedure was used if one was available.  At times Snomed CT had codes for specific findings (for example, a high, low, normal or abnormal level), but not a code for the more general finding.

     11== LOINC Mapping

     13The LOINC mapping was carried out using the [http://search.loinc.org/ Search Loinc] and [http://www.hipaaspace.com/Medical_Billing/Coding/Logical_Observation_Identifiers_Names_Codes/LOINC_Codes_Lookup.aspx HIPAA Space] LOINC search engines.

     15LOINC has a lot more codes for the tests required and seems to provide a better match for the codes from the iLab system.  LOINC provides multiple codes for each test depending on the sample analysed (blood, or serum or plasma) and the units used (mass/volume, moles/volume, count/volume, etc).  The units for each test are recorded in iLab and so a match could be made.  Where available both sample codes were recorded so that Paul Smalley could be given a choice when he checked the results.
