Adequate dialysis treatment is primarily indicated by improvements in laboratory values, particularly urea levels. Urea is a waste product that builds up in the blood when the kidneys are not functioning properly. During dialysis, the treatment aims to remove excess urea and other toxins from the blood. An improvement in urea levels signifies that the dialysis process is effectively filtering the blood, removing waste substances, and contributing to better overall metabolic balance in the patient.

Monitoring these laboratory values is crucial as they provide quantifiable data about the efficacy of treatment and the patient's status. Regular assessments of blood urea nitrogen (BUN) levels help healthcare providers determine how well dialysis is working and make necessary adjustments to the treatment plan.

While beneficial changes in weight, medication requirements, and other health indicators can also suggest effective treatment, the laboratory values, specifically urea levels, remain the most direct and quantifiable measure of the dialysis process's success.
