Background: Vasopressin, secreted in equimolar amounts with copeptin, is implicated as a stimulus for ACTH secretion during dynamic tests, such as Glucagon Stimulation Test (GST) or Insulin Tolerance Test (ITT). Some individuals with intact ACTH-cortisol axis, demonstrate, however, a lack of further cortisol stimulation during GST. We have assessed whether failure of further ACTH-cortisol increase during GST may be associated with an inadequate vasopressin/copeptin release.</p...

The reference ranges of thyroid function tests during pregnancy are still being debated, even in ethnically homogenous populations. The defining of the normal range is of importance, as it influences therapeutic decisions, particularly the use (or over-use) of levothyroxine in this vulnerable population. The study was aimed at the longitudinal assessment of thyroid function tests results in marginally iodine sufficient Polish population of pregnant women. The study was perform...

IntroductionDiagnostics of thyroid dysfunctions is frequently based on the measurements of TSH serum concentration only. Currently, due to a tendency to minimize stressful situations for a child (such as venipuncture to take a blood sample), some tests (i.e. TSH assessment) are performed at the Primary Healthcare Centre while other diagnostic tests (e.g. during an infection) are run. If TSH serum concentration is outside the reference range, it leads to ...
