Typically FSH, estradiol and thyroid function, often with LH. Ferritin, a full blood count, testosterone and vitamin D are common additions depending on the symptoms. The useful contents depend on what question you are trying to answer.
What is on it
Las Vegas testing: each marker, and what it shows
FSH usually gets the most attention on a Las Vegas lab report, though it is the marker least able to stand on its own. FSH rises as the ovaries become less responsive, so a sustained high reading supports the picture. During perimenopause it swings day to day, which limits what a single result proves.
Estradiol tells you what estrogen was doing that morning. In perimenopause it can be high, normal or low within the same month, so it is more useful as a baseline before treatment than as a diagnostic.
Thyroid function and ferritin are the two that most often change management. Both mimic menopause closely, both are common in this age group, and both are treatable once identified. Worth reading next: fsh and estradiol testing, hormone testing and thyroid testing go further into it. The two markers most likely to change what we do next in Las Vegas are not the sex hormones at all, which is an argument for running the full panel.
