Muscle deterioration, also known as muscle atrophy or muscle wasting, is the progressive loss of skeletal muscle mass and strength. It is caused by prolonged inactivity, malnutrition, chronic diseases like cancer or kidney failure, neurological disorders, and aging-related sarcopenia. The Microalbumin Random Urine with Creatinine test is the most important test for assessing muscle deterioration because it measures creatinine levels, a direct byproduct of muscle metabolism that decreases as muscle mass declines.

Muscle deterioration is caused by prolonged immobility, inadequate protein intake, chronic diseases such as cancer or chronic kidney disease, neurological disorders like muscular dystrophy or amyotrophic lateral sclerosis (ALS), severe infections, and age-related sarcopenia. When muscles are not used regularly or when the body lacks sufficient nutrients, muscle protein breaks down faster than it can be rebuilt. Hormonal imbalances, particularly low testosterone or growth hormone levels, and inflammatory conditions like rheumatoid arthritis also accelerate muscle loss by disrupting normal muscle metabolism.
The Microalbumin Random Urine with Creatinine test is the most important test for muscle deterioration because it measures creatinine levels, which directly reflect muscle mass and metabolic activity. Creatinine is produced during muscle metabolism, so lower than normal creatinine levels in urine indicate reduced muscle mass and severe muscle wasting. This test allows healthcare providers to quantify the extent of muscle loss and track changes over time, making it essential for monitoring disease progression or improvement with treatment interventions.
You should get tested if you notice unexplained muscle weakness, difficulty performing daily activities like climbing stairs or lifting objects, visible reduction in muscle size, unintentional weight loss, or chronic fatigue that limits physical function. Testing is especially important if you have been bedridden for extended periods, have a chronic illness like kidney disease or cancer, are experiencing rapid aging-related muscle loss, or notice that your muscles appear smaller despite maintaining your usual diet and activity level.

What this means
Your testosterone levels are slightly below the optimal range. While this is not necessarily cause for concern, it may contribute to occasional fatigue, reduced motivation, or lower muscle mass over time.
Recommended actions
Increase resistance or strength training
Prioritize 7–8 hours of quality sleep per night, try to reduce stress
Include more zinc- and magnesium-rich foods (like shellfish, beef, pumpkin seeds, spinach)
Consider retesting in 3–6 months
Not overhyped or overpriced. Just comprehensive blood testing made simple and for everyone.
