85624-5 Kidney failure 2-year risk [Likelihood] by KFRE

Term Description

The two-year "treated kidney failure" risk as calculated by the Kidney Failure Risk Equation (KFRE), for patients with chronic kidney disease stages 3 to 5. "Treated kidney failure" is defined as kidney failure that is treated with either dialysis or kidney transplant. The KFRE includes the following variables: patient age, sex, estimated glomerular filtration rate (eGFR), and urinary albumin-creatinine ratio (ACR). In this model, all variables are time-independent, in that the baseline measurement is used for all calculations. PMID: 26757465

LP101395-4   Sex
In LOINC, sex refers to the biological sex of an organism, which is most commonly determined based on anatomy and physiology or genetic (chromosome) analysis. Our definition is based on the World Health Organization's definition of sex and gender: sex (male, female) refers to biological and physiological characteristics, and gender (masculine, feminine) refers to socially constructed roles, behaviors, activities, and attributes.

32294-1 Albumin/Creatinine [Ratio] in Urine

Part Descriptions

LP32035-5   Creatinine
Creatinine or creatine anhydride, is a breakdown product of creatine phosphate in muscle. The loss of water molecule from creatine results in the formation of creatinine. It is transferred to the kidneys by blood plasma, whereupon it is eliminated by glomular filtration and partial tubular excretion. Creatinine is usually produced at a fairly constant rate and measuring its serum level is a simple test. A rise in blood creatinine levels is observed only with marked damage to functioning nephrons; therefore this test is not suitable for detecting early kidney disease. Creatine and creatinine are metabolized in the kidneys, muscle, liver and pancreas.

LP6118-6   Albumin
A non-glycosylated protein that is synthesized in the liver parenchymal cells, regulated by colloid osmotic pressure from interstitial fluid surrounding hepatocytes, and catabolized in nearly all organs. Albumin comprises >50% of plasma proteins in plasma, CSF and urine, and therefore is a key contributor to intravascular oncotic pressure and regulating fluid concentration in tissues. Albumin also binds and transports a variety of endogenous substances and medications. Serum albumin measurement is a reflection of hydration and nutritional status, blood oncotic pressure, liver and kidney function, and other chronic diseases, and the ratio of albumin in the CSF and serum can be used to evaluate blood brain barrier disorders. [Tietz] Urine albumin of less than 30 mg/day is considered normal. Microalbuminuria is defined as urine albumin of 30-300 mg/day and is an early sign of kidney damage from disorders such as diabetes or hypertension. Albuminuria is urine albumin >300 mg/day and is associated with overt kidney disease. PMID: 25512779 Source: Regenstrief LOINC

Change Reason

System changed from "Ser/Plas" to "Ser/Plas/Bld". According to the National Kidney Disease Education Program (NKDEP) Lab Working Group, estimated GFR may be calculated based on blood, serum, or plasma creatinine levels. Whole blood methods are calibrated to be the same as serum/plasma methods, and the isotope dilution mass spectrometry (IDMS) reference measurement procedure is the same for whole blood, serum, and plasma.
