What is this test?
This is the recorded date of your most recent dialysis treatment. Dialysis is a treatment that filters waste and excess fluid from the blood when the kidneys cannot do so adequately. It is a care-tracking item rather than a blood or laboratory measurement.
Why might I need this test?
Your care team may review the date to confirm that dialysis is being performed as planned and to guide follow-up visits, laboratory testing, medication decisions, and other kidney care. It may also be used when you are admitted to a hospital or evaluated for possible kidney failure.
How is the test performed?
The information is usually obtained by reviewing your dialysis center's records, treatment schedule, or electronic health record. If needed, the healthcare team may ask when you last received treatment.
How do I prepare for the test?
No special preparation is required. Bring your dialysis schedule, treatment cards, or portal information if available, and tell your care team if you recently missed treatment or received dialysis somewhere else.
Reference range
Adult: 10-40 U/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
An accurate date helps clinicians determine how recently dialysis was performed and whether treatment is current. It may influence the timing of blood tests, medication management, and other care, especially during hospitalization. Tell your care team promptly if the recorded date is incorrect or if you are not receiving dialysis as scheduled.
