high Rt3, ratio, and out of range labs

[froggykar]

Brand new to site and new to detailed Thyroid info. labs out of range/ratio. Very confused. Help please!

History: diagnosed LADA (T1 diabetes) 3 years ago. On insulin and metformin. Started thyroid meds about same time.
Currently on Tirosint 88 and have been on this amt for over 1 yr.
Recent past FT3 labs (two separate testings over the last month or so) came back:
2.2 L        (Range 2.3-4.2) with
TSH .875  (Range: .350-5.500)

Dr. prescribed 5 cytomel without much more info. Started some reading re thyroid. Did not start cytomel as I wanted additional testing. So...


Redid FT3 test again with additional tests last week. These most recent labs came back as follows:

TSH: 0.337 L (Range .350-5.500)
FT4:  1.65     (Range: .89-1.76)
FT3:  2.4       (Range:  2.3-4.2)

Anti-TG  <20  (Range <41)
TPO       33    (Range <61)
Thyroglobulin (TG)  2.4  (Range: <55)

RT3:    443 H   (Range: 90-350)

Iron Serum: 67 (Range:30-170)
TIBC: 284        (Range: 250-450)
Ferritin: 48       (Range: 10-291)

Vit B12:  1219 H  (Range: 211-911)
Vit D 25:  50.5     (Range: 30-100)

What does all this mean--the very high RT3 and Vit B!2, especially? My Dr. keeps saying I have Hashi's, but do the labs indicate this? interpretation and some direction would be so appreciated!!

Thank you!

Results from 1012 were:

TSH:   2.441 (rR .350-5.500)
FT4:    1.27   (rR: .89-1.76)
TPO:   37      (rR; <61)
Anti-TG: <20  (rR: <41)
C3 complement: 86.2 L  (rR: 90.0-170.0)

FT3 was not done at the time.

Thank you, gimel.

If you still have lab test results from 2012 please post them, along with reference ranges.  I'd like to see what the doctor used to diagnose Hashi's at that time and start you on thyroid med.

gimel: current symptoms would be tiredness only.

gimel: Thank you for staying with me here.  I thought the reason for the high RT3 was oversupply of T4 from Tirosint, hence the reduction in my Tirosint dose. No?
My endo sent me an email ( in response to my latest labs) which said: "take the Cytomel". There was no further instruction. I'm not comfortable with that. And at this point I'm now questioning whether I need any thyroid med at all. The labs from 2012 and most recent do NOT show elevated hashimotos antibodies.

Red Star and Barb135: Thank you both for responses and for the info and sources. (I will look for that video.)
My experience with T1 and low carbing does allow me to take a lesser amount of insulin, particularly meal time bolus. I feel safer operating this way, as I have found it difficult to consistently correctly cover meal time carbs. Even with the identical meal on two different days, and the identical amount of insulin, I can have pretty different results, depending on factors i do know about--such as exercise, and factors only my body knows about!

LCHF is not for everyone and does not guarantee that all diabetics will be able to reduce to one insulin shot/day... My son was diagnosed Type I diabetic at the age of 10 (he's now 43), eats LCHF and still needs multiple shots/day... You have to follow your body.

Okay well too much B12 then.  That was easy. :)  A video that is worth checking out: Troy Stapleton - I Manage My Type 1 Diabetes By Eating LCHF.  LCHF stands for low carb high fat.  I don't think he mentions how many carbs he eats on the video but I found online he eats under 50 grams a day of carbohydrate. This is a poll of those who have hypothyroidism eating LCHF...

"Question:

Are you on thyroid medication for hypothyroidism? Have you started an LCHF diet after being diagnosed? What happened?


After I started an LCHF diet I...

...had to increase the hormone dose a lot.  8.67%  (28 votes)


...had to increase the dose a bit  11.46%  (37 votes)


...need the same dose.  41.18%  (133 votes)


...could decrease the dose a bit.  14.55%  (47 votes)


...could decrease the dose a lot.  11.76%  (38 votes)


...could stop taking thyroid hormone.  12.38%  (40 votes)


Total Votes: 323"

Now if you have to increase the thyroid dosage then consider the bonus of 1 injection of insulin a day. I think this is a no brainer for me as I hate injections. :)


Diet Doctor: One Year on an LCHF Diet with Type 1 Diabetes...

"How does an LCHF diet work with type 1 diabetes? Here’s a one-year update:

Today I celebrate 1 year with LCHF, or I could say that I celebrate 1 year in good health! I can certainly endorse the LCHF diet as being good for type 1 diabetics.

Besides a more stable blood sugar and a more easily managed diabetes, I’ve gotten rid of pain in my legs, headaches, GI problems, and constant throat infections. Previously, I had recurring yeast infections, but during this past year I haven’t had a single one!

I only need one injection daily, instead of the previous 5-9. I eat delicious food, and I don’t miss anything. I have more energy and I’m happier than ever before! During the past year I’ve also gotten to know, and come in contact with, a lot of great people through Instagram and my blog!

I could go on about more positive things, but now I’m off to make dinner. A fatty, smoked rainbow trout to honor the day!"
