How this service works
LOINC lab test codes: look up a code or search by test name, with the long name and a deprecated-code warning.
Output
Returns the LOINC code, its official long name, component, a summary description, a verdict on validity, a deprecated boolean flag, the data source URL, an 'asOf' timestamp, and a disclaimer. May include a list of reasons and a 'degraded' flag if the data source is partially unavailable.
Example use cases
EHR lab result code verification
“I have a lab result tagged with LOINC code 2160-0 — can you tell me what the full official name is and whether that code is still current or has been deprecated?”
Clinical documentation code search
“I need to find the LOINC code for a hemoglobin A1c test — can you search by that test name and give me the top 5 matching codes with their long names?”
Health data pipeline enrichment
“We're ingesting lab data with LOINC code 17861-6 and need the long name and component details, plus a flag if the code is deprecated — can you look that up?”
Technical details
Endpoint
GEThttps://medical-codes.x402tookit.com/loinc-lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve or validate a specific LOINC code, look up its official long name and component, or search for LOINC codes by lab test name. Prefer this over ICD-10 or HCPCS endpoints when the data involves laboratory observations and measurements rather than diagnoses or billing supply codes.
Side effects
- Unknown LOINC code returns null or empty result with no match
- Misspelled or ambiguous search term returns zero results
- Deprecated code returns result with deprecated=true and a warning in reasons
- Service degraded flag set to true when upstream LOINC data source is partially unavailable
- Invalid query format (empty string) may return an error
