Clarify applicable standards for lab results

There is a need for appropriate lab codes (LOINC and SNOMED) to pass from LIS to EHR.  The codes need to be readily available in the EHR.  We are aware that this is a known issue: https://www.healthit.gov/public-course/interoperability-lab-exchange/HITRC_lsn1085/docs/LIS_Implementation_Challenges_Guide.pdf Lab results that are physical quantities should use UCUM for units. Coded lab results for microorganisms should use SNOMED CT.  Antimicrobial susceptibility test interpretation should use HL7 V3 Observation Interpretation.  

Applicable stsandards for lab results

The Regenstrief LOINC team recommends adding the following Applicable Standard(s) text to the Values/Results row: “SNOMED CT for qualitative results, UCUM units of measure to accompany quantitative results.”
