LOINC Code 14350-3: Specific gravity Refractometry (Syn fld)

14350-3 is a LOINC code used to identify Specific gravity Refractometry (Syn fld) in laboratory and clinical observation data. You may see this code in lab systems, lab reports, EHR exports, interoperability feeds, or other structured clinical data exchanges. LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Observation. It is commonly used with the system or sample type Synv fld.
