What Does This Test Measure?
This test quantifies manganese intake by analyzing your dietary consumption over a full day. Unlike blood or urine tests, which measure manganese levels in your body, this test focuses on what you eat and drink.
Why Might You Need This Test?
Your healthcare provider may order this test if you have symptoms or conditions linked to manganese exposure, such as chronic kidney disease, certain genetic disorders, or if you work in environments with high manganese exposure.
How Is the Test Performed?
You’ll keep a detailed food and drink diary for 24 hours, recording everything you eat and drink. This diary helps track manganese sources like nuts, tea, or supplements. No blood or lab sample is drawn for this test.
What Are Common Food Sources of Manganese?
Common dietary sources of manganese include whole grains (like brown rice), nuts (such as almonds and peanuts), dark chocolate, tea, and some vegetables like spinach. Processed foods and refined sugars typically contain less manganese.

Frequently asked questions
High manganese intake over time may pose risks, especially for individuals with kidney issues or genetic conditions affecting manganese metabolism. Chronic exposure can lead to neurological symptoms or other health concerns. This test helps monitor dietary habits to prevent excess intake.
A high manganese intake may indicate overconsumption of manganese-rich foods or supplements, which could be linked to dietary habits or specific health conditions. Your healthcare provider will review your results in the context of your overall health and symptoms.
This test is typically not a routine screening. It may be recommended periodically if you have known risk factors for manganese exposure, such as kidney disease or occupational hazards.
