The age term is (140 – age). This means that a 20-year-old person (140 – 20 = 120) will have twice the creatinine clearance as an 80-year-old (140 – 80 = 60) for the same level of serum creatinine. The C-G equation assumes that a woman will have a 15% lower creatinine clearance than a man at the same level of serum creatinine.
The typical human reference ranges for serum creatinine are 0.5 mg/dL to 1.0 mg/dL (about 45 μmol/L to 90 μmol/L) for women and 0.7 mg/dL to 1.2 mg/dL (60 μmol/L to 110 μmol/L) for men. The significance of a single creatinine value must be interpreted in light of the patient's muscle mass.
The proportion of AST to ALT in hepatocytes is about 2.5:1, but because AST is removed from serum by the liver sinusoidal cells twice as quickly (serum half-life t 1/2 = 18 hr) compared to ALT (t 1/2 = 36 hr), so the resulting serum levels of AST and ALT are about equal in healthy individuals, resulting in a normal AST/ALT ratio around 1.
Heart disease, high blood pressure, anemia [3] [4] Duration: Long-term [5] Causes: Diabetes, heart failure, high blood pressure, glomerulonephritis, polycystic kidney disease [5] [6] Risk factors: Smoking, genetic predisposition, low socioeconomic status [7] Diagnostic method: Blood tests, urine tests [8] Treatment
Creatinine might not be a direct indicator of protein toxicity; however, it is important to mention that creatinine could increase due to overwork by the kidneys exposed to high levels of protein waste. Also, high serum creatinine levels could indicate decreased renal filtration rate due to kidney disease, increase byproduct as a consequence of ...
In medicine, the urea-to-creatinine ratio (UCR [1]), known in the United States as BUN-to-creatinine ratio, is the ratio of the blood levels of urea (mmol/L) and creatinine (Cr) (μmol/L). BUN only reflects the nitrogen content of urea (MW 28) and urea measurement reflects the whole of the molecule (MW 60), urea is just over twice BUN (60/28 ...
While in general creatine supplementation resulted in slightly elevated creatinine levels that remained within normal limits, supplementation did not induce renal damage (P value< 0.001). Special populations included in the 2019 Systematic review included type 2 diabetic patients [ 73 ] and post-menopausal women, [ 74 ] bodybuilders, [ 75 ...
GGT is also elevated in 30% of the hepatitis C patients. GGT can increase by 10 times in alcoholism. GGT can increase by 2 to 3 times in 50% of the patients with non-alcoholic liver disease. When GGT levels is elevated, the triglyceride level is elevated also. With insulin treatment, the GGT level can reduce.
