Renal labs are diagnostic tools that detect kidney dysfunction before it reaches advanced stages. These tests measure how well kidneys filter waste from the bloodstream. Main markers include eGFR, which indicates filtering efficiency with normal values above 90 mL/min/1.73m², serum creatinine with normal ranges of 0.74–1.35 mg/dL for men and 0.59–1.04 mg/dL for women, and BUN with a normal range of 7–20 mg/dL. Understanding renal function labs helps nurses identify early warning signs and interpret renal panel labs while recognizing when kidney labs require immediate clinical intervention.
Approximately 8% of the general population has elevated liver enzymes, yet many people feel confused when they receive abnormal results. Up to 30% of these elevations resolve on their own within three weeks. Liver function tests use a blood sample to measure substances made by the liver. They assess how well it works and whether damage may be present. We'll break down what ALT, AST, and ALP values mean in this piece. You'll learn why liver enzymes become high and how to interpret the hepatic enzyme results. (31 pages)
