2 - 4 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Royal blue-top (EDTA) tube
Separate plasma immediately, and transfer to a certified metal-free plastic transport tube (PeopleSoft N° 111166) for shipment to the laboratory.
Maintain specimen at room temperature.
Certified metal-free plastic transport tube not submitted
Evaluate industrial exposure
In evaluating toxicity, the serum level may have returned to normal while neurological damage persists. In evaluating possible deficiency states, the human deficiency syndrome is poorly defined, making interpretation difficult. Levels are reportedly reduced mildly in epilepsy, and raised in hepatitis or jaundice. Manganese levels are 60% lower than normal in hemodialysis patients.
This test was developed and its performance characteristics determined by LabCorp. It has not been cleared or approved by the Food and Drug Administration.
Inductively-coupled plasma/mass spectrometry (ICP/MS)
Environmental exposure: <2.5 μg/L
Toxic exposure may occur from dry cells, fungicide (maneb), and in the steel industry or chemical industry. Manganese is present in the coloring agents for glass and soap, in paints, varnish, enamel, and in linoleum. It is used in the manufacture of chlorine gas and now in lead-free gasoline. Industrial manganese poisoning has been recognized since 1837. Some water supplies are sufficiently contaminated by manganese that endemic psychiatric and neurological disease is present.
