Dialysis Adequacy Test

This test measures how well your dialysis treatments are cleaning your blood. It checks the level of waste products, such as urea, in a blood sample taken before and after a dialysis session, so your care team can see how much waste was removed during treatment.

The Water Ammonia Test measures the concentration of ammonia (NH3) in water samples. Ammonia in water can come from natural sources, industrial contamination, or bacterial breakdown of organic matter. This test is crucial in healthcare settings where water is used for critical medical procedures.

A nurse or technician takes a small blood sample, usually from your dialysis access, at the beginning and again at the end of one of your dialysis sessions. The samples are sent to a laboratory, where the results are compared to calculate how effectively the treatment removed waste from your blood.

A water sample is collected from the designated source (such as a dialysis machine water supply). The sample is then analyzed using chemical methods to determine the ammonia concentration. The result is typically reported in moles per volume (mol/L) or milligrams per liter (mg/L).

This test helps your care team make sure you are receiving enough dialysis to stay healthy. If the results show that too much waste is remaining in your blood, your doctor can adjust your treatment plan, which may lower your risk of problems such as fatigue, poor appetite, heart strain, and hospital stays.

In dialysis treatment, the water used must meet strict purity standards. High ammonia levels in dialysis water can be toxic to patients, as ammonia can enter the bloodstream during treatment. Regular testing ensures patient safety and prevents complications from waterborne contaminants.
