LOINC Code 72159-7: Inulin renal clearance/1.73 sq M (Stdy U+S/P) [Vol rate/Area]

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 Inulin renal clearance/1.73 sq M. It is commonly used with the system or sample type Urine+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: Both

What it does not mean

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

Key facts

• Inulin renal clearance/1.73 sq M in Urine and Serum or Plasma
• Inulin renal clearance/1.73 sq M
• Inulin is measured to evaluate kidney function by determining the glomerular filtration rate (GFR) -- the flow rate of filtered fluid through the kidney. Inulin is completely filtered at the glomerulus, allowing the clearance of inulin to be used as a highly accurate measure of GFR. The submitter laboratory's testing approach is to collect samples every 30 minutes up to 240 minutes after an 18 hour infusion with inulin (long test) or after an initial bolus injection (short test).
