Method
LC-MS/MS — steroid panel
Liquid chromatography–tandem mass spectrometry
Compounds are separated chromatographically in time, then each is confirmed by a mass-to-charge transition specific to that molecule. The result is a structural measurement of the target analyte rather than an estimate of how strongly an antibody binds.
Orderable panels 3
- Sex steroid profile components bill separately
Not a billable panel. Each component bills under its own CPT. See individual analyte pages for reportable ranges — DHT and estradiol both carry range limitations relevant to specific clinical questions.
- Corticosteroid profile components bill separately
Not a billable panel. Each component bills under its own CPT.
- Thyroid profile components bill separately
Not a billable panel. There is no AMA-defined thyroid panel, so each component bills under its own CPT — TSH 84443, free T4 84439, free T3 84481. Total T4 (84436) and total T3 (84480) are available individually and are not components of this profile.
