Mass Spectrometry Based Cutoffs for Cortisol After Stimulation Tests

Norway232 participantsStarted 2016-05-21

Plain-language summary

There are two main stimulation tests used to decide if a patient has cortisol deficiency. It is the "synacthen test", were we stimulate the patient with intramuscular or intravenous synacthen ( ACTH) to see how much cortisol the adrenals are capable of producing, and it is the "Insulin hypoglycemia test" were we give the patient insulin to provoke a hypoglycemia, and look at the adrenal response to that stimulus. The cut off values for a normal response is based on old immunological assays no longer in use. Assays with a lot of interference and cross reactivity leading to measurement of higher values for cortisol than what we measure on the highly specific LCMS/MS ( Liquid chromatography mass spectrometry methode) that we are using for cortisol today. So, there is a need for new cut off values for a normal response to such tests. The purpose of this study is to produce such new cutoff values by performing the test in 120 healthy controls. We also want to perform the test in patient groups normally going trough this tests according to the same protocol as the control persons, to evaluate the new cutoffs in different patient groups.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

Define a cutoff level for serum cortisol after stimulation with synacthen or hypoglycemia in healthy control persons.
