Why urine tests matter
Urinalysis and urine protein measurements can detect changes that may suggest kidney involvement. Results need interpretation in clinical context.
Kidneys & lupus
Kidney involvement can be quiet, which is why monitoring matters.
Lupus nephritis is inflammation of the kidneys related to lupus. Changes can sometimes appear in urine or blood tests before a person feels obvious kidney symptoms.

Kidney function
Blood tests such as creatinine help clinicians assess kidney function, but no single number tells the whole story.
Kidney biopsy
In selected situations, a kidney biopsy may help determine the type and severity of kidney inflammation and guide treatment decisions.
Treatment and monitoring
Treatment depends on the pattern and severity of kidney involvement. Follow-up may include urine, blood pressure, kidney function and other laboratory monitoring.
What to ask
Ask whether your urine or kidney results have changed, what trend your team is following, how often monitoring is needed and which symptoms should prompt earlier contact.
What should I do now?
Write down new or changing symptoms.Keep your medicines and recent results organized.Prepare your most important questions before your visit.Seek medical assessment promptly for severe or rapidly worsening symptoms.
