When Should You Worry About Protein in Your Pee? Expert Guidelines Revealed
Published: Oct 08, 2023
Medical guidelines help doctors decide when to worry about protein in your urine. Let's break down what the experts say about proteinuria.
The Numbers Game
According to guidelines, normal protein excretion is less than 150 mg per day. Anything above this might warrant further investigation. For albumin specifically, excretion above 30 mg per day is considered 'moderately increased albuminuria' - what doctors used to call microalbuminuria. This level can be an early warning sign, especially in people with diabetes or high blood pressure.
Who Needs Screening?
Guidelines don't recommend routine screening for proteinuria in healthy adults under 60. However, they do suggest regular checks for high-risk groups. This includes people with diabetes, high blood pressure, or a family history of kidney disease. It's like having a smoke detector - you want it in place for those at higher risk of fire.
When to Take Action
If protein is detected, guidelines suggest confirming it with a second test. Persistent proteinuria (protein in your urine on multiple occasions) usually requires further evaluation. This might include blood tests, imaging studies, or sometimes a kidney biopsy. The level of proteinuria can guide treatment decisions - higher levels often indicate more urgent need for intervention.
Frequently Asked Questions
Small amounts (less than 150 mg/day) are usually considered normal.
Guidelines often suggest annual screening for high-risk groups.
It varies, but often considered for persistent proteinuria over 1 g/day.
Guidelines: Your Health Roadmap
