About this test
Cystatin C is a blood test that measures the level of a small protein produced by most cells in your body. Unlike some other markers, cystatin C levels are less affected by muscle mass, age, diet, or creatine supplement use, making it a reliable indicator of how well your kidneys are filtering your blood (glomerular filtration rate, or GFR). Elevated cystatin C levels typically indicate reduced kidney function, sometimes even before changes in traditional markers like creatinine are seen.
Who should take this test?
- People who want a more precise assessment of their kidney function, especially if their muscle mass is unusually low or high
- Those who have had ambiguous results from other kidney function tests (like creatinine or eGFR)
- Individuals with risk factors for kidney disease (such as diabetes, hypertension, or a family history of kidney problems)
- Individuals over 60, as kidney function can naturally decline with age

“Deeper insights than a typical annual physical”
I learned much more about my health than what I would typically get from my annual provider check up. I was able to tweak some things and can already notice improvements. Thank you!
“Mito Health made change for me”
Throughout my life (now I'm 67) I was not ready to break my lifestyle for the sake of a more attractive appearance. Looking at the results from Mito Health, I got motivated to lose weight.
“Tired of arguing with my PCP. Mito got me the answers I was looking for.”
After extensive research, I decided Mito was the best option. The physician insights were also very clear and make sense. Mito gave me peace of mind, and a path to follow to correct deficiencies.
“Easy sign up and plenty of customizations for test options”
The draw was easy. Just handed them the order form and was in and out quickly. The dashboard was helpful providing commentary on my results with actionable recommendations.
