I posted here a few days ago regarding results from a blood test i had done via Medichecks. I had some great advice and because the Thyroid test only tested TSH and Free Thyroxine i was informed it didnt really provide a full picture. Therefore i decided to get the full Thyroid blood test done and would appreciate any feedback. Please note the tests were only done a few days apart (not sure if that makes any difference) In my prevous test i also found i was low in vitamin D (37.3 nmol) and have been supplenting now for about a week. I also have b12 injections every 3 months. (Last one was a week ago) im still not feeling 100% however do feel slightly less tired but am getting on and off lightheadedness, pins and needles and achy joints so not sure if this is related toblow vitamin D, B12 or Thyroid, or something else. Anyway here are both results for comparison..
Results from test on 25.07.19:
TSH - 0.901 MIU/L (0.27 - 4.2)
FREE THYROXINE- 12.3 PMOL/L (12-22)
Results from test on 31.07.19.
TSH - 1.61 MIU/L (0.27 - 4.2)
FREE THYROXINE - 13.9 PMOL/L (12 - 22)
FREE T3 - 4.37 PMOL/L (3.1 - 6.8)
THYROGLOBULIN ANTIBODIES - <10 KIU/4 (<115)
THYROID PEROXIDASE ANTIBODIES - 9.94 KIU/L (<34)
As you can see TSH and T4 have increased a bit from the first test but are they still on the low side? I recieved some excellent advice feom seasidesusie who said that i should restest in a few months because i had a baby almost 5 months ago, which can affect hormones. I do plan on doing this so wont jump to conclusions based on these results, but handy to have for comparison in a fee months time.
Thanks x

Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and fasting. This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip, best not mentioned to GP or phlebotomist)
Last Levothyroxine dose should be 24 hours prior to test, (taking delayed dose immediately after blood draw).
Us this how you did the test?
FT4 is too low in both tests. This suggests you need dose increase in Levothyroxine
How much Levothyroxine are you currently taking?
Do you always get same brand of Levothyroxine at each prescription
Perhaps discuss small dose increase in Levothyroxine with GP
Dr Toft, past president of the British Thyroid Association and leading endocrinologist, states in Pulse Magazine,
"The appropriate dose of levothyroxine is that which restores euthyroidism and serum TSH to the lower part of the reference range - 0.2-0.5mU/l.
In this case, free thyroxine is likely to be in the upper part of its reference range or even slightly elevated – 18-22pmol/l.
Most patients will feel well in that circumstance. But some need a higher dose of levothyroxine to suppress serum TSH and then the serum-free T4 concentration will be elevated at around 24-28pmol/l.
This 'exogenous subclinical hyperthyroidism' is not dangerous as long as serum T3 is unequivocally normal – that is, serum total around T3 1.7nmol/l (reference range 1.0-2.2nmol/l)."

Ask your GP to test folate and ferritin
You will need to retest vitamin D after 3-4 months
B vitamins best taken in the morning after breakfast
Recommended brands on here are Igennus Super B complex. (Often only need one tablet per day, not two. Certainly only start with one tablet per day after breakfast. Retesting levels in 6-8 weeks ).
Or Jarrow B-right is popular choice, but is large capsule
If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 7 days before any blood tests, as biotin can falsely affect test results
Im not on any Thyroid medication. Haven't been diagnosed with any Thyroid disorder - I decided to test myself as i have not been feeling right. GP carried out Thyroid test as well as iron etc. when i was pregnant and said was normal (although I dont know the results and ranges) my Ferratin level is fine. Im taking 5000iu vitamin D3 ( this should be my dose according to vitamin D council) also taking with D2 MK7. Not sure what folate level is but think i had this tested by Gp when they tested B12 level.
My B12 was very low - 91 last October and i was pregnant at the time. Had loading injections and then put on injections every 3 months. Most recent one was 2 months overdue though due to changing GP surgeries. There was a suggestion that i may have Pernicious Anemia where my body is unable to absorb B12 properly, but my antibodies test for that came back negative so have not had an official diagnosis. However from my understanding and research, there is no definitive 'gold standard' test for this and results are unreliable 40 - 60% of the time, so i may in fact have it even with a negative result.
Yes i had post partum hemmorage during birth. I lost about a litre of blood but luckily did not need surgery or a transfusion. However i have to take iron tablets for a while. I have looked into sheehans syndrome and it may be a possibility, but i don't seem to have many of the symptoms it describes. I.e hairloss, low blood pressure, no periods etc.
As you say i doubt my GP will think these results stem to a Thyroid problem so not sure if it is worth showing her my results, and suggesting they look into sheehans and Central hypothyroidism?.. Is it possible low TSH and T4 will rectify itself in a few months, maybe hormones are still a bit haywire 5 months post birth? I plan on testing again, as well as vitamin D in about 3 months time to see if results hace changed or not. Could my symptoms be due to low vitamin D and a belated b12 injection? Im just trying to peice together what may be causing me to feel out of sorts. Like i said i do feel slightly less tired since having the b12 but there has been no dramatic reduction in symptoms. Vitamin D supplements i have been taking for a week so maybe not enough time to notice anything yet...
