Hello Chuck,

My name is Cora coming from HK. I was diagnoised to have Hypothyroidism in

November 2010 when i delivered a baby about 7 months ago. Would you help me to

interpret the findings. Many thanks

my findings in April 2011 are

Free T4: 16.2

TSH: 2.58

HBs Ag : Negative

Anti- thyoid microsamal antibody: postive, Tire 1:400

Since i took a blood test in public hospital  so that i could not have the Free

T3 test . And i am going to have one in May

What does it mean 1:400? What is the normal range? And i am taking about three

quarter of 50mcg thyroxine. And the doctor said if my figures within the normal

range, he would help me to reduce the dosage gradually. However, as i know for

the Hashimoto, it is better not to stop the medications. Would you have any

advice for me. Besides, in HK, i never find a doctor who would adopt the

desiccated thyroid supplement, What can i do ?

many thanks!

Cora

Actually, no. FT4 is converted to EITHER RT3 or T3, in about equal amounts, but

your system is sensitive to the ratio of FT3 to RT3. Elevated RT3 not only means

that too large a fraction of T4 is not going to T3, but the RT3 blocks the T3

receptors in the cells. This double whammy makes the RT3 indicator more

sensitive. However, such an imbalance is relatively rare, which is why few

doctors resort to it without serious indications of conversion issues. Roni is

one of the clear exceptions.
