Blood test results - grateful for any help analysing them!

[surreygirl1987]

Hi all, I just got my blood test results back this morning (taken on CD3) and have just spent the past hour or so trying to analyse them. They have come back with everything as ‘normal’ which is obviously great news, but I am surprised too as I have some symptoms of both Hyopthyroidism and PCOS so am also a little frustrated that there’s not an obvious ‘quick fix!

Below are some of the main results and some questions I have about them for anyone who is really kind and more knowledgable than me! I’ve not included the full blood count results or urea or electrolytes as I they are normal and I didn’t anticipate any issues with them.

FSH: 5.1
LH: 9.1
TSH: 2.1

Firstly, while my FSH and LH numbers seem fine, I have read that a 1:2 ratio can be a sign of PCOS. Should I take this further with my GP?

Secondly, I don’t like my TSH number. My test says normal is 0.3-3.94 but thyroiduk.org.uk says for conception it should be 0.5-2 so I’m just outside the upper end... and I have read elsewhere that it should be as close to 1 as possible.

With that in mind, is it worth getting my T3 and T4 tested too? I was surprised they weren’t part of the test as I had specifically asked to be tested for hypothyroidism. Is there anything else I need testing for thyroid / low temperature / circulation issues?

Any advice would be gratefully received - the support on here is so appreciated! I’m going to make an appointment to speak to my GP about my results ASAP but she doesn’t seem to know much about fertility at all (eg at my last appointment she told me that all women definitely have a 14 day luteal period) so I want to be well informed before I speak to her - I get the impression my GP is the gateway to testing but not specialised enough for th detaled analysis! :(

Hm. Those numbers are pretty good, but I would have exactly the same questions as you.

Do you have any pcos symptoms? It's probably worth a scan to see if you have polycystic ovaries. Are your cycles regular? Do you ovulate most/ every cycle? TBH there isn't much they can actually DO about PCOS besides help you ov if you don't already. Metformin can help regularise some people's cycles if yours aren't already but that is simply to encourage regular ovulation... Losing weight is supposedly helpful. I am trying to get to BMI 20-22 as 'some evidence' suggests this can be helpful for conception.

Your TSH looks great. Anything below 2.5 is good to go for ttc. At 2.1, your dosing would be ridiculously low and pose a very real DANGER of you turning hyper which is super dangerous. At 2.3, my GP said my TSH was a 'total non-starter.' Despite the fact that I used to take thyroxine and have diagnosed hypothyroidism and my levels used to be much higher. My GP is not at all helpful with ttc and is a massive pain, but he was just following the guidance.

Thanks so much for the reply, @physicskate. No I'm not overweight (at least not for my height; I'm heavy but tall!); my BMI is generally low 20s and acrually when I stated to ttc my body fat percentage was only 19% I think so I purposefully started eating full fat stuff to get it up to a better ttc %.
I do have (embarrassingly) one symptom of PCOS which is unusual hair; hairs I have to pluck out of my chin, the occasional one on my chest, and lots on my abdomen! However I had an ultrasound in April when was still on the pill (because my body was doing a weird two periods a month thing) and nothing was flagged up then. It's the 1:2 ratio that I'm wondering about now!

Your thyroid comments are interesting: I've read that TSH closer to 1 is optimum for conception... is that not correct? Your GP's comments must be frustrating!

Anyway thanks for the time you have taken to read my plea for help and for yiur insight! :) It's scary not really knowing what it all means and knowing my GP doesn't really know either! Will make another appointment with her and ask to be tested for T4 at least!
