LOINC Code 77253-3: Albumin/Creatinine DL <= 1.0 mg/L (U) [Ratio]

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 Albumin/Creatinine. It is commonly used with the system or sample type Urine.

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
• Method: Detection limit <= 1.0 mg/L

What it does not mean

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

Key facts

• Microalbumin/Creatinine [Ratio] in Urine by Detection limit <= 1.0 mg/L
• Albumin/Creatinine
• Measures the albumin excretion in urine to aid in the early detection of kidney disease (and increased risk of cardiovascular events) for patients with diabetes. Normal 24 hour urine albumin excretion is less than 30 mg/day in adults. 24-hour urine excretion results between 30-300 mg/day are defined as microalbuminuria (MAU) which may occur with kidney damage. While a 24-hour urine is preferred, a random urine sample can be tested as well.
