Kt/V

Kt/V is a measure used to evaluate the effectiveness of dialysis in removing waste from a person’s blood. It represents the ratio of the amount of cleaning (clearance, K) multiplied by the time of dialysis (t) to the volume of the patient’s total body water (V). A higher Kt/V indicates more efficient removal of toxins. Think of it like a cleaning rate: how much “dirt” is cleaned from the blood relative to the amount of water in the body. Healthcare providers use Kt/V to ensure dialysis is effectively maintaining a person’s health.
