Lipid profile (total cholesterol, triglycerides, HDL cholesterol, LDL cholesterol) derived from a 24-hour urine collection

Why This Test Is Done

Your doctor may order this test if you have symptoms like unexplained fatigue, swelling in your legs, or if tests suggest your kidneys aren’t working well. It can also be part of routine checks for people at higher risk of kidney disease, especially those with diabetes, high blood pressure, or a family history of kidney problems.

What to Expect Before the Test

You’ll need to collect all your urine for 24 hours, starting and ending the collection at the same time each day. Drink plenty of water to help your urine flow normally. Avoid certain medications or supplements that might affect fat levels in your urine, as discussed with your doctor.

How the Test Works

Your urine sample is analyzed to measure specific fat-related substances, including cholesterol and triglycerides. These substances are broken down differently in your body, and their presence in urine can reflect how well your kidneys filter them out.

What the Results Mean

High levels of these substances in urine may indicate problems with fat metabolism or kidney function. Your doctor will compare your results with what’s typical for healthy individuals and discuss them with you based on your overall health.
