Panels that include this biomarker

  • Iron, Total and Total Iron Binding Capacity 7573

    3 analytes · Serum · Fasting not stated · Turnaround Set up: Mon-Sat; Report available: 3 days

    Method and collection
    Method
    Spectrophotometry (SP)
    Preparation
    Samples should be taken in the morning from patients in a fasting state, since iron values decrease by 30% during the course of the day and there can be significant interference from lipemia.

Verify these ranges and sources

We compile this page from named laboratory catalogs, guidelines and studies. Labs calculate reference intervals from the people they test, for one assay method and one population group, so an interval describes that population rather than an optimal target.
