Test Details
Methodology
Inductively coupled plasma/mass spectrometry (ICP/MS)
Result Turnaround Time
5 - 9 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.
Use
Evaluate manganese stores
Specimen Requirements
Specimen
Packed RBCs and plasma
Volume
3 mL each plasma and packed RBCs
Container
Royal blue-top (EDTA) metal-free tube; metal-free transfer tubes
Collection Instructions
Both packed cells and plasma are required. Separate before shipping. Failure to separate may cause rejection due to hemolysis of red cells and contamination of the plasma. Transfer RBCs and plasma into separate plastic, acid-washed, trace metal-free tubes. Specimen must be received at the testing facility within five days of collection.
