Description
Why It’s Done:
The 24-hour PCR test may be recommended for the following reasons:
• Detect and monitor kidney disease: Such as diabetic nephropathy, glomerulonephritis, or hypertensive kidney disease.
• Assess kidney function: Especially in patients with conditions like diabetes, hypertension, or autoimmune diseases.
• Evaluate severity of proteinuria: Helps guide treatment decisions and monitor disease progression.
• Screen for preeclampsia: In pregnant women showing signs of high blood pressure and protein in the urine.
• Monitor effects of treatments: For kidney disorders or systemic illnesses affecting the kidneys.
Preparation:
• No fasting required: You can eat and drink normally unless your doctor advises otherwise.
• Medication disclosure: Inform your healthcare provider about all medications and supplements, as some can affect urine protein levels.
• Follow collection instructions carefully:
o Discard the first urine sample of the day (start with an empty bladder).
o Collect all urine passed over the next 24 hours, including the first urine the next morning.
o Store the urine container in a cool place, preferably refrigerated.
