Advice on my blood tests please.

DoodleMoo profile image
9 Replies

I would be very grateful if anyone could advise me on my latest blood results. I have an appointment with my Endocrinologist on Saturday. I am currently taking 50mg of Levothyroxine and 20mcg Thybon Henning in the morning and 10mcg Thybon at 4 pm.

T3 4.63 (3.1 - 6.8)

T4 8.6 (11.0 - 23.0)

TSH 0.01 (0.27 - 4.5)

My Endocrinologist looks at TSH and as I am feeling as well as I have to date, I am nervous she will drop my dosages as TSH is suppressed.

Thanks very much.

Looking at previous posts..before T3 was added you were on 125mcg daily?

Think your levothyroxine has been reduced too much. Many find levothyroxine only needs reducing by 25mcg …..or less

Many, many members find they need BOTH Ft4 and Ft3 at least 50-60% through range

Ft4 is BELOW RANGE

FT3: 4.63 pmol/l (Range 3.1 - 6.8)

Ft3 only 41.35% through range

Suggest you increase levothyroxine to 75mcg daily and retest in 8-10 weeks

ALWAYS Test thyroid levels early morning, ideally before 9am and last dose levothyroxine 24 hours before test

Day before test split T3 into 3 smaller doses spread through the day….and last 1/3rd of daily dose approx 8-12 hours before test

You may find you need less T3 as levothyroxine dose is increased slowly upwards

When were vitamin D, folate, ferritin and B12 levels last tested

What vitamin supplements are you currently taking

On almost any dose of T3 TSH is almost always suppressed….it’s irrelevant

Most important results are always Ft4 and Ft3

Thank you very much for your reply.

Yes, I was on 125mcg Levothyroxine daily. The last year or so has been a bit of a nightmare chopping and changing doses, on/off with mixing in Armour, and now back to decreasing Levo and building up T3. I was at my worst on Armour 0.5 grains + T3 20mg .

Some of my vitamins were last done in March 2022:

B12 578ng/l (197.0 - 771.0)

Folate 503ug/l (2.0 - 18.7)

Ferritin 227.7ug/l (20.0 - 260.0)

Vit D 62 nmol/L

I take selenium, zinc, magnesium, vit C, probiotics and vit B complex (Igennus) and Omega 3 on a regular basis.

suggest changing vitamin B complex to Thorne next time

Igennus contains vitamin C. Vitamin C might increase how much iron you’re absorbing and ferritin is already quite high

Vitamin D needs improving to at least around 80nmol minimum

Folate result….did you mean 5.03?

Yes, sorry - folate is 5.3ug/l! I will work on upping my Vitamin D and change to Thorne next time for Vitamin B. Thank you so much for pointing that out to me.

Thank you very much for your advice.

folate is low

In week before blood test, when you stop vitamin B complex, you might want to consider taking a separate methyl folate supplement and separate B12

Hi SlowDragon.

I have finally retested myself (Medichecks) after raising Levo to 75mg daily and T3 20mg AM and 10mg PM since our last communication.

TSH 0.01 (0.27 - 4.2)

FT4 8.9 (12 - 22)

FT3 5.3 (3.1 - 6.8)

The only thing I didn't do was split my AM T3 dose but took 20mg 24 hours before and 10mg 12 hours before.

My symptoms are a bit confusing to me: I generally feel okay but sometimes maybe over medicated - racing heart and lots of hot sweats. Lots of hair loss + eyebrows and eyelashes again. On the other hand I have had significant weight gain (not just Christmas!) and sometime my feelings of being cold have returned.

I would be very grateful for you advice.

Thanks very much, Fiona

well we are all different

But I would suspect you need LESS T3 and more levothyroxine

Ft4 is still way below rangev

Suggest you try reducing T3 by 5mcg per day.

After 2-3 weeks on lower dose T3 ……then try increase levothyroxine to 87.5mcg

Retest in 6-8 weeks

Most people when adequately treated find they need both Ft4 and Ft3 roughly equal through range

Thank you so much for your advice. I will try your suggestion.

Would it be best to reduce my T3 in the AM or PM? At the moment I take 20mg AM and 10MG PM (around 4.30pm)?

Not what you're looking for?
