D25 43.3 range (30.0-100.0)

Folate 9.4 ( >3.0 ng)

TSH 0.583 ( 0.450-4.50)

T3 Total 105 ( 71-180)

T3 free 2.6 ( 2.0-4.4)

Ferritin 43 ( 15-150)

No medication was taken morning of the blood test.

I am on 50 mcg levothyroxine on 5 days a week and 75 levothyroxine two days a week.

What do u think?

My dizziness/ vertigo may be a factor.

No FT4 or B12?

Your FT3 is very low, but can't tell if that's because you're under-medicated (you probably are!) or because you're a poor converter without an FT4 reading.

Hair-loss could either be due to low T3 or low ferritin.

Your folate is rather low, so your B12 could be, too, and that could be the cause of your dizziness.

Your vit D is also very low.

But without full testing, it's difficult to say anything more.

Have antibodies been tested?

Suggest you increase levothyroxine to 75mcg 4 days a week and 50mcg 3 days

Retest in 6-8 weeks

Meanwhile working on improving low ferritin by increasing iron rich foods in your diet

Low ferritin levels linked to hairloss

No B12 result

No Ft4 result either

I had increased levothyroxine dose 75mcg to 3 days, doctor suggested reducing to 2 days due to palpitations.Last blood test B12 was good.

Thanks

D25 43.3 range (30.0-100.0)

This result is not very low, it is within the recommended range for the unit of measurement used.

With that reference range and the fact that you are in the US then the unit of measurement will be ng/ml and the Vit D Society, Grassroots Health and the Vit Council all recommend a level between 40 and 60ng/ml, with a recent blog post on Grassroots Health suggesting 50ng/ml. If the unit of measurement was the usual one for the UK, ie nmol/L, then yes it would be low because the recommended level with nmol/L is 100-150 which corresponds to 40-60ng/ml.

Folate would be better in double figures.

Hair loss/ Alopecia Reason?

Ferritin/Iron and hair loss article:

thyroidpharmacist.com/artic...

particularly the part where it says:

According to some experts, ferritin levels of at least 40 ng/ml are required to stop hair loss, while levels of at least 70 ng/ml are needed for hair regrowth. The optimal ferritin level for thyroid function is between 90-110 ng/ml.
