Can a blood test explain tiredness, low libido or weight changes?
Hormones may be part of the explanation, but the same symptoms can arise from sleep, medicines, nutrition or other health conditions. Describe when the change started and how it affects daily life. Focused testing answers a specific hormone question; a broader panel adds context from general-health markers. Results are most useful when linked to a clear symptom history.
Why check SHBG, LH and FSH alongside testosterone?
Total testosterone measures circulating testosterone overall. SHBG is a protein that binds sex hormones and helps put that result in context. LH and FSH are signals from the pituitary gland involved in reproductive function. A physician uses the pattern, rather than one number alone, to decide whether further evaluation is needed and which tests will be informative.
Does one low testosterone result mean I need TRT?
No. In men, diagnosis of testosterone deficiency requires compatible symptoms and consistently low testosterone. This generally means measurements on two separate early mornings. Illness and sampling conditions can influence results. Kauri reviews symptoms and laboratory findings together before discussing TRT; focused testing or suitable external results can be part of that assessment.
What do thyroid tests and menstrual-cycle timing add?
TSH and free T4 help assess thyroid function, which can affect energy, temperature tolerance and weight. Reproductive hormones such as estradiol and progesterone change through the menstrual cycle, so the same value can mean different things at different times. Tell us your cycle dates, contraceptive use and hormone medicines so collection and interpretation match the question.
Does hormone testing commit me to hormone treatment?
No. Testing helps explain what is happening and guides the next discussion. A result may support reassurance, repeat measurement, changes to an existing treatment or further evaluation. Bring outside reports with their dates, units and reference ranges. If you already use hormonal treatment, tell us the product and the time of your last dose so comparisons are meaningful.
