What This Test Measures
Your sample will be analyzed for indicators such as protein excretion, sodium, potassium, creatinine, and other electrolytes. These measurements help track kidney function, fluid retention, and mineral balance during pregnancy.
Why It Matters During Pregnancy
Pregnancy places unique demands on your body’s systems. This test helps identify whether you’re retaining too much fluid, managing electrolytes properly, or maintaining kidney efficiency—all of which are vital for both you and your baby’s health.
Sample Collection and Preparation
You’ll collect all urine produced in a 24-hour period in a special container. Drink plenty of fluids during this time, but avoid excessive caffeine or medications that may affect test results unless instructed otherwise.
Common Findings and Their Implications
High protein levels might indicate kidney strain, while abnormal electrolyte levels could signal dehydration or mineral imbalances. Your healthcare provider will review these results alongside your clinical picture to guide next steps.
Reference range
INR: 0.8-1.2 (warfarin: 2.0-3.0)N/A
Inform your healthcare provider if you are taking blood thinners. No special preparation required.
