What is a common laboratory test used to monitor dialysis patients?

The serum creatinine test is a common laboratory test used to monitor dialysis patients due to its importance in assessing kidney function. Creatinine is a waste product generated from muscle metabolism, and healthy kidneys filter it from the blood. In patients with kidney dysfunction, such as those undergoing dialysis, serum creatinine levels typically rise because the kidneys aren't able to efficiently remove it. Therefore, by regularly measuring serum creatinine, healthcare providers can gauge how well dialysis is working for the patient and adjust treatment plans as necessary.

Monitoring serum creatinine also helps indicate the overall progression of chronic kidney disease and can provide insight into other complications that may arise from renal failure. While other tests, like a complete blood count or electrolyte panel, are certainly important in managing the health of dialysis patients, serum creatinine specifically relates to the effectiveness of renal function and dialysis treatment.
