LOINC Code 72392-4: Cortisol/Cortisone [Mass ratio]

72392-4 is a LOINC code used to identify Cortisol/Cortisone [Mass ratio] 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 Cortisol/Cortisone. It is commonly used with the system or sample type Ser/Plas.

What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Cortisol/Cortisone. It is commonly used with the system or sample type Ser/Plas.

When is it used?

  • Used in lab systems, EHRs, and clinical data exchange.
  • May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
  • Status: ACTIVE
  • Order vs observation: Observation

What it does not mean

  • The code identifies the observation or test, not the actual result.

Key facts

  • Cortisol/Cortisone [Mass Ratio] in Serum or Plasma
  • Cortisol/Cortisone
  • Apparent mineralocorticoid excess is a rare recessive genetic disease that is characterized by childhood onset of hypertension, hypokalemic alkalosis, and low plasma renin and aldosterone level. Hypertension is due to impaired conversion of cortisol to cortisone due to an inactive 11β-hydroxysteroid dehydrogenase. This condition may be diagnosed with elevated cortisol metabolite to cortisone metabolite ratios in urine or serum. It is recommended that cortisol/cortisone ratios (F/E) be tested in hypokalemic hypertension cases where aldosterone, deoxycorticosterone, and renin are all low. Elevated cortisol/cortisone ratios may be found in chronic renal failure, or excessive ingestion of glycyrrhetinic acid or derivatives, or in liver or bile-acid abnormalities.
