Hi could I have some advice please on my full thyroid blood test results that came back today.
I am currently in my first trimester of pregnancy. Iam taking prenatal vitamins topping up with D3 2000iu + Calcium with magnesium tablet+ Iron. Still taking levothyroxine 100mcg pre-pregnancy dose. I would really appreciate some feedback especially medication dose to chase up with Gp.
Also really interested to know does the result show any sign if my hypothyroidism changed into an autoimmune? I was first diagnosed with hypothyroidism in August 2019 ,start off medication was 100mcg and wasn't changed since then. I was always given same levo~ brand. I have been trying to get off gluten, dairy and eat as clean as possible . it's challenging but taking steps towards the right direction of improving to make positive dietary changes.
Test results as follows:-
Vitamin b12 - 635 Pg/ml range 197-771
Folate (serum) 10.9 ug/L range >2.9
Ferritin - 47 ug/L. range 13-150
C reactive protein *8.5mg/L range <5
Total thyroxine (T4) 102 nmol/L range 59-154
TSH 3.55 mIU/L range 0.27-4.2
Free Thyroxine 16.1 pmol/L range 12.0-22.0
Free T3 4.2pmol/L range 3.1-6.8
Thyroglobulin antibody <10.0 IU/mL range 0-115
Thyroid peroxidase antibodies <9.0 IU/mL range 0-34
25 OH vitamin D 53 nmol/L range 50-200
Reverse T3 *28 ng/dL 10-24.
Many thanks

Eating iron rich foods, plenty of red meat, pumpkin seeds and dark chocolate, plus daily orange juice or other vitamin C rich drink can help improve iron absorption
This is interesting because I have noticed that many patients with Hashimoto’s disease and hypothyroidism, start to feel worse when their ferritin drops below 80 and usually there is hair loss when it drops below 50.
How long have you been taking vitamin D at 2000iu.
What could it mean Reverse T3 being higher than the range?
I wouldn't worry about that. High rT3 can be caused by many things, but only one is to do with the thyroid and that is when there is a build up of unconverted T4 and you don't need a reverse T3 test to show this, it will be shown by a high FT4 and a low FT3 which is not the case with you as your FT4 is only 41% through range.
It could be caused by low ferritin, or high cortisol, by an infection, by low-calorie diets, etc
Things that can cause high reverse t3 include selenium or zinc deficiency, cortisol issues, stress, dieting, chronic illness, inadequate or low iron, chronic inflammation, high cortisol, or liver issues and any other chronic health issues. and probably several more things.
Other conditions that contribute to increased Reverse T3 levels include:
· Chronic fatigue
· Acute illness and injury
· Chronic disease
· Increased cortisol (stress)
· Low cortisol (adrenal fatigue)
· Low iron
· Lyme disease
· Chronic inflammation
Also selenium deficiency, excess physical, mental and environmental stresses. Also Beta-blocker long-term use such as propranolol, metoprolol, etc. Physical injury is a common cause of increased RT3, also illnesses like the flu. Starvation/severe calorie restriction is known to raise RT3. Diabetes when poorly treated is known to increase RT3. Cirrhosis of the liver. Fatty liver disease. Any other liver stress Renal Failure. A fever of unknown cause. Detoxing of high heavy metals.
