Clinical relevance

Steroid hormones are structurally derived from cholesterol and play a role in a wide range of physiological processes, including carbohydrate metabolism, fat and protein metabolism as well as in stress response. They are secreted by the adrenal cortex, testes, ovaries, and during pregnancy by the placenta. They are transported through the bloodstream to the cells of various organs where they influence and regulate the organs’ physiological functions.

The determination of hormones is important for the diagnosis of a number of diseases such as adrenogenital syndrome, hyperaldosteronism, or tumours. By using LC-MS/MS, not only high sensitivity and specificity can be achieved, but also the efficient measurement of multiple analytes in a single run.


Product advantages

  • 13 steroids – 2 panels – 1 analytical column
  • One sample preparation for all parameters
  • Each parameter safeguarded by its own internal standard


The MassChrom® Steroid reagent kit allows the quantitative determination of 13 steroid hormones in serum/plasma by LC-MS/MS and includes the clinically most relevant parameters. Sample preparation is identical for the two steroid panels and is conducted by means of an efficient solid phase extraction using individual SPE columns (Sample Clean Up Columns). Optionally, there is another method available from Chromsystems that uses 96 SPE well plates. The use of stable isotopically labelled internal standards for each analyte ensures reproducible and reliable quantification of the steroids. This method also does not require a high-end LC-MS/MS system.

  4. Centrifuge 1 min at 200 x g, check for complete run through, discard effluent
  5. Add 2 x 1 ml Wash Buffer and centrifuge 1 min at 200 x g
  6. Centrifuge 2 min at 3000 x g to dryness, discard effluent
  7. Place Steroid 96 SPE Well Plate onto Steroid Collection Plate or put autosampler vials with conical bottom into tubes for sample preparation, then put Sample Clean Up Columns on top
  8. Add 500 µl Elution Buffer and centrifuge 1 min at 200 x g

Clean-up and injection

  1. Evaporate eluates in Steroid Collection Plate or autosampler vials under nitrogen or compressed air at 45­°C to dryness
  2. Reconstitute with 100 µl Reconstitution Buffer, close autosampler vials with crimp caps
  3. Shake Steroid Collection Plate  for 2 min at 900 rpm or vortex autosampler vials for 15 s
  4. Centrifuge 5 min, collection plate at 3000 x g, autosampler vials at 15000 x g
  5. Seal Steroid Collection Plate with adhesive seal, transfer to autosampler
  6. Inject 10–40 µl eluate into the LC-MS/MS system
