    Thyroid Labs for Dixiewrecked

    Lexapro can possibly effect cortisol testing. Am I correct in guessing that it hasn't helped with the lethargy? OpenEvidence: Escitalopram can affect cortisol blood tests. Multiple randomized controlled trials and clinical studies have demonstrated that escitalopram, a selective serotonin...

    Thyroid Labs for Dixiewrecked

    Am I understanding this correctly? 8am cortisol was 10 ug/dl, then at noon it was still 10 ug/dl? What time do you normally wake up? If you normally wake up around 4am then it may be normal. Noon cortisol should be somewhere around 1/2 the morning cortisol level. A flat cortisol curve can be...

    Thyroid Labs for Dixiewrecked

    This is from OpenEvidence: Glucocorticoids—including oral, intravenous, inhaled, topical, intra-articular, and intranasal formulations—are the medications most commonly associated with disruption of the normal daily cortisol rhythm. Chronic or supraphysiologic dosing suppresses the...

    Thyroid Labs for Dixiewrecked

    My 2 cents, I agree that sounds low. Are you taking any glucocorticoids like Hydrocortisone, Prednisone, Triamcinolone? Azole antifungals? Opiates? I'd test cortisol at 8am along with ACTH. Anything under 10 ug/dl at 8am, especially with low or low normal DHEAS, then I'd pursue adrenal...

    New to TRT. Received first labs. Concerned and need help.

    Post exertional malaise is usually what distinguishes ME/CFS from other types of fatigue. PEM can be exacerbated by physical, mental, and/or emotional exertion. Basically, if you work out too hard or do too much (physically or mentally) do you crash for a week? This is a good review...

    Quest Free T reference range change in 2025?

    Just curious if anyone knew why they changed the reference range? The reference range used to be 46-224pg/ml for free testosterone by equilibrium dialysis. In 2025 it changed to 35-155pg/ml. That's roughly 1.4% of the total testosterone reference range (250-1100ng/dl). 1.4% of 250 is 35. 1.4% of...

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
