Understanding Lab Tests for Muscle Deterioration
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Muscle deterioration, also known as muscle wasting or muscle atrophy, is typically diagnosed through physical examination, imaging studies, and functional assessments. While there isn't a single blood test to directly diagnose muscle deterioration itself, laboratory testing plays a fundamental role in monitoring the body's metabolic response and assessing the extent of muscle breakdown.
Recommended Test
Microalbumin, Random Urine with Creatinine
This urine test measures creatinine levels, which is a byproduct of muscle metabolism. Low urine creatinine levels can indicate severe muscle wasting, as reduced muscle mass produces less creatinine. This test helps assess the extent of muscle deterioration and monitor changes in muscle metabolism over time.

Why Lab Testing is Important for Muscle Health
Laboratory tests are essential for evaluating muscle metabolism, identifying underlying causes of muscle loss, and monitoring the progression of muscle deterioration. These tests help healthcare providers understand how muscle breakdown is affecting overall body function and guide appropriate treatment strategies.
Understanding Your Results
Creatinine levels in urine reflect muscle mass and metabolic activity. Lower than normal creatinine levels may suggest muscle wasting, while tracking changes over time can help monitor the progression of muscle deterioration or improvement with treatment.
