Understanding Lab Tests for High Protein Diet
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
A high protein diet is a dietary approach that emphasizes increased protein intake, typically representing 25-35% or more of total daily calories. While there is no single blood test to diagnose whether someone follows a high protein diet, certain lab tests can reveal the metabolic effects and impacts of increased protein consumption on the body.
Top Recommended Test
Urea Nitrogen (BUN)
This test measures urea nitrogen, a waste product created when the body breaks down protein. A high protein diet typically increases urea production as more protein is metabolized, which may lead to elevated BUN levels. This test helps monitor kidney function and protein metabolism efficiency.

Why Blood Testing is Important for High Protein Diets
Blood tests are fundamental for monitoring how your body responds to increased protein intake. These tests can help assess protein metabolism, kidney function, and overall nutritional status, ensuring that your high protein diet is supporting your health goals without causing adverse effects.
Other Relevant Tests
Albumin
This test measures albumin, a major protein produced by the liver. Higher albumin levels can reflect increased protein intake, as greater dietary protein consumption can lead to elevated albumin production in the body. Monitoring albumin helps assess how well your body is utilizing the increased protein.

Understanding Your Results
These tests can provide valuable insights into how your body is processing increased protein intake. Elevated levels may indicate that your high protein diet is having measurable metabolic effects, while also helping ensure that your kidneys are handling the increased protein load effectively.
