Codes from http://snomed.info/sct|http://snomed.info/sct/83821000000107/version/20250702Codes from Logical Observation Identifiers, Names and Codes (LOINC)
26604007Full blood countmaps loosely to57021-8CBC W Auto Differential panel - BloodAn England FBC usually includes the white cell differential. Without it, 58410-2 CBC panel - Blood by Automated count. The LOINC panel members are not the same as a laboratory's FBC.
252167001Urea and electrolytesmaps loosely to24321-2Basic metabolic 2000 panel - Serum or PlasmaNo LOINC panel matches U&E (sodium, potassium, urea, creatinine, eGFR). The basic metabolic panel also has glucose, calcium, chloride and bicarbonate, and no eGFR.
26958001Hepatic function panelmaps loosely to24325-3Hepatic function 2000 panel - Serum or PlasmaSame test, different members: the LOINC panel has AST and direct bilirubin. An England LFT is usually bilirubin, ALT, ALP, albumin and total protein, with GGT at some laboratories.
271244005Measurement of serum lipid levelmaps loosely to24331-1Lipid 1996 panel - Serum or PlasmaThe LOINC panel is cholesterol, HDL, calculated LDL and triglyceride. An England lipid profile usually adds non-HDL cholesterol and the cholesterol/HDL ratio.
135842001Serum C reactive protein levelis narrower than1988-5C reactive protein [Mass/volume] in Serum or PlasmaThe LOINC code is serum or plasma; the SNOMED CT concept is serum. High sensitivity CRP is a different code (30522-7).
371981000000106Hb A1c (Haemoglobin A1c) measurement - IFCC (International Federation of Clinical Chemistry and Laboratory Medicine) standardisedis equivalent to59261-8Hemoglobin A1c/Hemoglobin.total standardized per IFCC-RMP for CDT in BloodIFCC standardised HbA1c, reported in mmol/mol.
47758006Hepatitis B surface antigen measurementis broader than5195-3Hepatitis B virus surface Ag [Presence] in SerumThe LOINC code is a qualitative (presence) test in serum; the SNOMED CT concept does not give the scale or specimen.
700152009Human papilloma virus screeningis broader than82675-0Human papilloma virus 16+18+31+33+35+39+45+51+52+56+58+59+66+68 DNA [Presence] in Cervix by NAA with probe detectionHigh risk HPV as tested in NHS cervical screening. The LOINC code names the HPV types, specimen and method, so the right code depends on the assay.
113076002Glucose tolerance testis broader than72171-2Glucose tolerance 2 hours panel - Serum or PlasmaThe 2 hour (75 g) oral glucose tolerance test. Gestational and other protocols have other LOINC panels.
401324008Urinary microscopy, culture and sensitivitiesis broader than50554-5Urinalysis microscopic panel [#/volume] - Urine by Automated countNo single LOINC order code for urine MC&S: it maps to microscopy, culture and susceptibility. Manual microscopy has other LOINC panels.
is broader than630-4Bacteria identified in Urine by CultureThe culture part of urine MC&S.
is broader than29576-6Bacterial susceptibility panelThe sensitivities part of urine MC&S.
