How often do creatinine levels change?

Change in creatine: Creatinine (c) can elevate acutely, in cases of low blood flow to the kidney, dehydration, obstruction to urine outflow and agents toxic to the kidney. When these issues are resolved, it can go down quickly as well. Renal diseases such as diabetes and glomerulonepritis (g) can elevate the c more slowly. Once the c is elevated in diabetes, it will not come down. If the g is treated, c can go down. ...Read more

How to keep creatinine levels above 20 mg/dl? I do not use drugs but need a drug urine test 3 times a week. The level of creatinine must be over 20 mg/dl. I changed nothing in my diet and recently had a level of 14.1 and was told i diluted. I am worrie

The : The most common reason for low creatinine is that you drink a lot of fluids. It is not abnormal to have low creatinine, it's just that the people doing the lab test want the urine concentrated enough that it can pick up trace amounts of the drugs they are testing for. Dilute urine= less of drug in urine sample. Some people have a medical condition that makes them unable to concentrate their urine (low levels of adh (vasopressin), (vasopressin) anti-diuretic hormone) release from the pituitary gland. If you don't have this condition, then on test days avoid liquids (sips ok, glasses not ok) until after the urine test. Best results would be to avoid liquids 4 hours before test. If creatinine is still low, you might want to see an endocrinologist to evaluate for low adh (vasopressin). If the doctor can validate this, then your employer can't legally hassle you about your low creatinine. ...Read more

Is 1.03 bad creatinine level?

Creatinine: Creatinine level depends on many things....Age, race, sex, muscle mass. For women, the usual creatinine is between 0.6 and 1mg/dl. For men, between 0.9 and 1.4mg/dl. As we age, the creatinine should lower slightly (less muscle mass). The number is important but so are the trends.
