T3 - Rt3 conversion and ratio

[Guest guest]

Hello all,

I am hoping that some kind sole in this group can help me out with a problem I

have in working out the ratio between the blood test results I have for T3 and

RT3.

I recently used Genova diagnostics to have my levels checked and had the results

back which were T3 - 10.4 pmol/L (2.6 to 5.7) and RT3 - 0.51pmol/ml (0.14 to

0.54). I also had my T4 and TSH done which were T4 - 15.2pmol/L and TSH 0.01

mu/L (0.2 to 5.5).

My t3 is so high because I am taking 2.5 grains of Armour Thyroid in an attempt

to reduce my previous RT3 resuly of 0.38 ug/l.

I am able to calculate the ratio betwen the latest blood test as both results

are measured using the same system ie pmol and I believe the ration to be

(10.4/0.51)=20.39 which I believe to be within the normal range althoug I have

my doubts given that the ration is only correct because of my high T3.

My previous results were T3 1.5nmol/L (1.3 to 3.1) and RT3 0.38ug/l (0.09 to

0.35).

The problem I have is that the above results are measured in nmol/L and ug/l and

as I understand it there is no simple way to calculate the ratio without first

calculating the molecular weight of both the T3 and Rt3.

I have contacted the Lab that did the first tests and they say that there is no

conversion formular available which to be honest I doubt very much as given the

importance of Ratio between T3 and RT3, the results as given are almost

pointless.

I hope that someone will be kind enough to look at my results and be able to

help me do the conversion so that I can make a comparison between my previous

results and the results taken since I have been taking Armour Thyroid.

I also had a Salivary Cortisol and DHEA test done which required me to take four

saliver samples at various times throughout the day and the results were as

follows.

Sample 1 8am 22.6 (12 to 22)

Sample 2 12am 1.5 (5 to 9) DHEA am 0.14

Sample 3 5pm 0.5 (3 to 7)

Sample 4 10pm 0.8 (1 to 3) DHEA pm 0.17

Total daily cortisol 25.4

DHEA mean 0.16 (0.2 to 0.7)

DHEA/Cortisol ratio 0.61 (0.6 to 3.0)

They say that this shows Resistance Stage 3 - Maladaptation but I have no idea

what this means of if it it relative to my thyroid results.

I would really appreciate any help that any of you can offer.

Many thanks

Many thanks for your reply Nick.

I had actually made a mistake when I said that I was taking 2.5 grains of Armour

Thyroid, it is actually 4.5 grains I am taking. Would it be possible for you to

review your reply with this in mind. Also, thanks for your advice to join the

Adrenal group. I will join it and ask them to look at my cortisol results.

Finally can you give me the website to order cytomel as I bought some in past

which were horendously expensive and I understand that there are cheaper places

offering generic t3 which are just as good as the brand name.

Thank you again for taking the time to respont to my questions.
