One blood tests is a snapshot in time so not especially reliable - and also depends where on your body you apply the patch and where the bloods were taken, and also when in relation to patch change day. I imagine my oestrogen level is about this - low 200's (last two times it was measured) although I haven't had this measured since I increased my patch dose slightly. I would say it is a low level for that amount of oestrogen but if you are feeling otherwise OK then that's fine? If you are not producing any at all (I think you've had the injection to shut down ovaries?) then you would need more (than me for example) to give just a basic level than those of is still with ovaries as I understand they continue to produce some oestrogen even post-menopause (I think).
The main thing is how do you feel?
