Hypothyroid results

[JenVanderhoven]

Hi, Can anyone help me interpret my thryroid results please?

8th August 2013 - TSH 1.8

8th June 2015 - TSH 8.8, Vit D 38.1, Cortisol 633, prolaction 288, FT4 10.6, FT3 5.1, Serum Thyroid peroxidase Ab >600.

I'm currently on 50mg levothyroxine

Do you have the ranges of your tests, please. Labs differ in their ranges and it makes it easier to comment although I do see your TSH has risen so you require your dose of hormones increased and 50mcg of levo is usually a starting dose.

[JenVanderhoven in reply to shaws]

TSH should be 0.27-4.2

FT4 should be 12-22

FT3 should be 3.1-6.8

Vit D should be >50

cortisol should be <536

antibodies should be <34

Jen, FT4 is below range. Will take a while to get it halfway to the upper quadrant.

VitD is low, optimal is 75-200 and most are comfortable around 100. Supplement 5,000iu for a 8 weeks then take on alternate days. Retest in 6 months and take vitD 4 hours away from Levothyroxine.

I have been given 200iu vit d to take - is this too low?

[Clutter in reply to JenVanderhoven]

jen, infants are given more than 200iu. My sister was prescribed 20,000iu x 2 weekly when vitD was 40.

Jen, Thyroid peroxidase antibodies are positive for autoimmune thyroid disease and it is this which has caused your hypothyroidism. Many people find 100% gluten-free diet helpful in managing Hashi flares and reducing antibodies.

TSH rises in response to low FT4 &/or low FT3.

TSH 8.8 is quite high, FT4 looks low but I can't be sure because you haven't included the lab ref range. FT3 is good but this probably due to your high TSH stimulating conversion.

50mcg is a starting dose which will improve FT4 and reduce TSH but you'll probably need an increase in dose in 6-8 weeks to bring TSH down to 1.0 which is comfortable for most people. Have a fasting (water only) blood draw early in the morning when TSH is highest and leave 24 hours between last dose and blood draw.

Members will need to see lab ref ranges to comment on cortisol and prolactin results or you can look on NHS Choices or labtestsonline.org to see what the tests mean.
