Labcorp catalog pageMethod and collection
- Method
- Liquid chromatography/tandem mass spectrometry (LC/MS-MS)
- Collection
- The blood is to be collected by venipuncture into a lavender-top tube containing EDTA and mixed immediately by gentle inversion at least six times to ensure adequate mixing. Do not separate. Transfer whole blood to a labeled amber plastic transport tube with amber stopper and freeze . For amber plastic transport tube and amber stopper, order Labcorp No. 23598. If amber tubes are unavailable, cover standard transport tube completely, top and bottom, with aluminum foil. Identify specimen with patient's name directly on the container and the outside of the aluminum foil. Secure with tape. To avoid delays in turnaround time when requesting multiple test on frozen samples, please submit separate frozen specimens for each test requested.
- Reference notes
- 137−370 µg/L (Note: Reference interval reflects Flavin Adenine Dinucleotide (FAD), which accounts for approximately 90% of the total riboflavin in whole blood.)

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.
