Ranges
Each lab publishes a reference range for the population groups it tests, usually the middle 95% of results. These intervals describe that population, not an optimal or healthy target. How ranges differ
Quest Diagnostics, Tacrolimus and Sirolimus, LC/MS/MS 70006
| Population | Interval |
|---|---|
| The following trough range is a suggested guideline: 5.0-20.0 mcg/L, Sirolimus | Trough: 3.0-18.0 mcg/L |

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.
