Cystatin C is a protein that is freely filtered in the glomeruli before it is reabsorbed and catabolized in the renal tubular cells. Its serum level is independent of muscle mass, making more accurate at estimating GFR than creatinine serum levels. [citation needed]
[10] [11] [12] Although studies are somewhat divergent, most studies find that cystatin C levels are less dependent on age, gender, ethnicity, diet, and muscle mass compared to creatinine, [13] [14] and that cystatin C is equal or superior to the other available biomarkers in a range of different patient populations, including diabetic patients ...
Diagnostic serum creatinine studies are used to determine renal function. [4] The reference interval is 0.6–1.3 mg/dL (53–115 μmol/L). [4] It is simple to measure serum creatinine, and it is the most commonly used indicator of renal function. [6]
Creatinine clearance exceeds GFR due to creatinine secretion, [4] which can be blocked by cimetidine. Both GFR and C Cr may be accurately calculated by comparative measurements of substances in the blood and urine, or estimated by formulas using just a blood test result ( eGFR and eC Cr ) The results of these tests are used to assess the ...
Outside the United States, blood tests made up of the majority of the same biochemical tests are called urea and electrolytes (U&E or "U and Es"), or urea, electrolytes, creatinine (UEC or EUC or CUE), and are often referred to as 'kidney function tests' as they also include a calculated estimated glomerular filtration rate. The BMP provides ...
On 1 January 1999 the ICD-10 (without clinical extensions) was adopted for reporting mortality, but ICD-9-CM was still used for morbidity. Meanwhile, NCHS received permission from the WHO to create a clinical modification of the ICD-10, and has production of all these systems: ICD-10-CM, for diagnosis codes, replaces volumes 1 and 2. Annual ...
ICD-10 is the 10th revision of the International Classification of Diseases (ICD), a medical classification list by the World Health Organization (WHO). It contains codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. [1]
Acute kidney injury (AKI), previously called acute renal failure (ARF), [1] [2] is a sudden decrease in kidney function that develops within seven days, [3] as shown by an increase in serum creatinine or a decrease in urine output, or both.
