24-Hour Urinary Manganese Excretion Rate
This test measures how much manganese your body excretes in urine over a 24-hour period. Manganese is a mineral that plays a role in metabolism, but high levels can indicate exposure or health concerns.

Why This Test Might Be Ordered
Your healthcare provider may recommend this test if you have symptoms like neurological issues, liver problems, or signs of manganese toxicity. It’s also used in research or occupational health settings to monitor exposure to manganese, often found in certain industrial jobs or from environmental sources.
What to Expect Before the Test
No special preparation is needed beyond collecting your urine over a full 24-hour period. You’ll typically start and end the collection at the same time each day, storing the urine in a container until it’s sent to the lab.
How the Test Works
The lab analyzes the total manganese content in your collected urine sample. This helps determine your body’s excretion rate, which can reflect how your kidneys and metabolism handle manganese.
Possible Results and Interpretation
Results are usually reported as the amount of manganese excreted per day (e.g., micrograms or milligrams). Your provider will compare these results to what’s considered normal for your body and context, such as exposure history or symptoms.
Reference range
Premenopausal: 20-400 pg/mL; Postmenopausal: <30 pg/mLN/A
No special preparation usually required. Stay well hydrated. Inform your healthcare provider of all medications and supplements you are taking.
