Why Is This Test Done?

Your healthcare provider may order this test if you have symptoms like frequent urination, excessive thirst, or signs of kidney problems. It can also be part of evaluating conditions like diabetes, genetic metabolic disorders, or kidney disease.

What Does the Test Involve?

A blood sample is taken from a vein, usually in your arm. The blood is then sent to a lab for analysis to measure mannose levels in your serum.

What Do Results Mean?

Results are compared to a general reference range, though exact values may vary by lab. Abnormal levels might suggest kidney issues, metabolic disorders, or other health concerns that need further evaluation.

What Are Possible Results?

Low mannose levels may indicate kidney problems or certain genetic disorders, while very high levels could be associated with metabolic conditions or errors in metabolism. Always discuss results with your doctor.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Clinical Significance: Mannose in Serum can help diagnose or monitor conditions like hereditary fructose intolerance, certain kidney diseases, or metabolic disorders. It may also be used to assess how well your kidneys filter waste products from your blood.

Short name

Mannose in Serum

Frequently asked questions

What causes abnormal mannose levels?
Abnormal mannose levels can result from kidney disease, genetic metabolic disorders (like hereditary fructose intolerance), or conditions affecting sugar metabolism. Your doctor may also check levels if you have symptoms like fatigue, nausea, or unusual thirst.
How is this test different from urine tests for mannose?
This test specifically measures mannose in your serum (blood plasma), whereas urine tests for mannose often assess excretion levels in urine. Serum tests can provide insights into overall blood sugar metabolism and kidney function, while urine tests may focus on filtering capacity.
Can diet affect mannose test results?
Dietary intake of sugars like fructose or glucose may influence mannose levels, but results are typically interpreted in the context of your overall health and medical history. Your doctor will guide you on how diet might impact your test results.
