Kidney Liver Function Screening in Arizona

What this test measures

The kidneys filter waste and excess fluid from the blood and produce urine. The liver processes nutrients, breaks down medications and toxins, and makes proteins and bile. Each organ has its own laboratory markers, and checking both gives a broader view of how the body is handling internal and external substances.

For the kidneys, common markers include creatinine, eGFR, blood urea nitrogen, and urine albumin. For the liver, common markers include alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, bilirubin, and albumin. A combined panel reports these values with reference ranges. Results are read together to build a complete picture.

A provider may order combined testing when reviewing medications that affect both organs, when evaluating a cluster of symptoms such as fatigue, swelling, or changes in urine or stool color, or as part of a general health assessment. Results are interpreted together because findings in one organ can influence the other. A qualified healthcare provider should evaluate the findings.
