The diagrams below take inter-cycle and inter-woman variability into account in displaying reference ranges for estradiol, progesterone, FSH and LH. Levels of estradiol (the main estrogen), progesterone, luteinizing hormone and follicle-stimulating hormone during the menstrual cycle. [88]
English: Reference ranges for the blood content of the hormones estradiol (the main estrogen), progesterone, follicle-stimulating hormone and luteinizing hormone during the menstrual cycle. As a rule of thumb, the narrower ranges may be used when more is known about the individual woman.
Reference ranges for the blood content of follicle-stimulating hormone levels during the menstrual cycle. [ 12 ] - The ranges denoted By biological stage may be used in closely monitored menstrual cycles in regard to other markers of its biological progression, with the time scale being compressed or stretched to how much faster or slower ...
Some other blood tests are suggestive but not diagnostic. The ratio of LH (luteinizing hormone) to FSH (follicle-stimulating hormone), when measured in international units, is elevated in women with PCOS. Common cut-offs to designate abnormally high LH/FSH ratios are 2:1 [101] or 3:1 [94] as tested on day 3 of the
"Providers are encouraged to consult with their local lab(s) to obtain hormone level reference ranges for both 'male' and 'female' norms, [which can vary,] and then apply the correct range when interpreting results based on the current hormonal sex, rather than the sex of registration." [3] Fenway Health: United States: 100–200 pg/mL <55 ng ...
Levels of estradiol in premenopausal women are highly variable throughout the menstrual cycle and reference ranges widely vary from source to source. [62] Estradiol levels are minimal and according to most laboratories range from 20 to 80 pg/mL during the early to mid follicular phase (or the first week of the menstrual cycle, also known as ...
Reference ranges for the blood content of luteinizing hormone (LH) during the menstrual cycle. [ 27 ] The ranges denoted By biological stage may be used in closely monitored menstrual cycles in regard to other markers of its biological progression, with the time scale being compressed or stretched to how much faster or slower, respectively, the ...
