 What does 1.9 creatinine level indicate? 

Creatinine is a waste product that is produced by the muscles and is normally filtered out of the blood by the kidneys and excreted in urine. Elevated levels of creatinine in the blood can be a sign of kidney dysfunction or impaired kidney function. The normal range for creatinine levels can vary slightly. However, in general, a normal creatinine level for adults is usually between 0.6 and 1.2 mg/dL. A level of 1.9 mg/dL would be considered higher than the normal range. In many cases, kidney disease can cause a decrease in the kidneys' ability to filter creatinine from the blood, leading to higher levels in the bloodstream. Dehydration can also lead to a temporary increase in creatinine levels because the kidneys may conserve water and reduce urine output, leading to higher concentrations of creatinine in the blood. In addition to these, some medications can affect kidney function and lead to elevated creatinine levels.
