Guest guest Posted April 27, 2009 Report Share Posted April 27, 2009 I posed this question on the Natural Thyroid Hormone group and only got one response and it was to see you folks here. I sure hope you can help. I have a feeling I am T3 resistant, just not sure. I am very confused by an issue I am having in figuring out my FT3/RT3 ratio. The STTM book (pages 161-162)says the following: " When you view your lab results, you might notice that your free T3 might be measured in PG (picograms) and your RT3 result might be measured in NT (nanograms). They are each just different units of measure, such as liters to pints. And the only way to find the ratio is to first convert one measurement to match the other. Since there are 1,000 picograms per 1 nanogram, you would move the decimal of picograms 2 spaces to the right, or move the decimal of the nanograms 2 spaces to the left. Or in other words, 10 PG equals .01 NG. When they are both in the same unit of measurement, you then divide your RT3 into your free T3. You are looking for a ratio greater than 19 if the free T3 was originally measured in pg/mL and the RT3 was in ng/mL. For example, say your free T3 is 600 and your RT3 is 200 (though the range for RT3 is up to 350). By dividing the 200 into the 600, the ratio will be 30-ideal!! On the other side of the coin, if your free T3 was 600 and RT3 was 400, and you divided the 400 into the 600, your ratio would be 15-not ideal and reveals your body is making too much RT3. " Well here is my labwork from 02/25/09 and on 105 mg of Armour TEST UOM RANGES MY RESULTS FREE T4 ng/dL .70-1.48 .97 FREE T3 pg/dL 210-440 209.00 T3, TOTAL ng/dL 97.0-219.0 115.00 T3 REVERSE ng/dL 11.0-32.0 31.00 NEAR TOP OF RANGE Labwork from 04/10/09 at 165 mg Armour TEST UOM RANGES MY RESULTS FREE T4 ng/dL .70-1.48 1.05 FREE T3 pg/dL 210-440 378.00 NOT YET TOP OF RANGE T3, TOTAL ng/dL 97.0-219.0 182.00 T3 REVERSE ng/dL 11.0-32.0 40.00 TOO HIGH Okay, here is the confusion. Based on the calculations from the STTM book the ratio is figured out as follows. 378.00 in pg converted to ng is 37,800 37,800/40 = 945 How can 945 be the correct ratio? If I make this calculation: 378/40 = 9.45 This is more realistic however based on what I read it is very low. Is there a mistake in the STTM book? My doctor wrote me an email after my tests and said, " Free T3 level much better this time. The reverse T3 is also a little higher due to more free T3 but the ratio is still ideal. " Does anyone have any official sites they know of that I can send the links to my doctor? I wanted something concrete I can give her to prove she has a misconception of what " ideal " is. So far I have found nothing. I was feeling really good for awhile. Afternoon sleepies were gone, constipation lifted after 9 years of only going once every 6 days, depression lifted, body temperature was normal plus a lot of other little things. Now it feels like I am sliding backwards. I would really appreciate some insight into this. I have not yet taken the adrenal stress saliva tests. I wanted to see what response I got from your group. Thanks, Hillary Quote Link to comment Share on other sites More sharing options...
Guest guest Posted April 27, 2009 Report Share Posted April 27, 2009 It is much simpler than thatyou simply divide 378 by 40 to get your ratio of 9.45 it needs ot be 20 or higher . You definitely have an RT3 problem. -- Artistic Grooming- Hurricane WV http://www.stopthethyroidmadness.com/ http://health.groups.yahoo.com/group/NaturalThyroidHormonesADRENALS/ http://health.groups.yahoo.com/group/RT3_T3/ http://groups.yahoo.com/group/HypoPets/ Quote Link to comment Share on other sites More sharing options...

Guest guest Posted April 27, 2009 Report Share Posted April 27, 2009 Thanks, that means the STTM is incorrect with how to do the calculations. Well at least now I understand what to do. It is okay to divide without converting the pg to ng. Also, do you know some kind of study that shows what the correct ratios should be? I want to site them to my doc and hopefully educate her that 9.45 ratio is not " ideal. " Then the next thing is, what do I do about this? Thanks, Hillary It is much simpler than that you simply divide 378 by 40 to get your ratio of 9.45 it needs to be 20 or higher . You definitely have an RT3 problem.

Guest guest Posted April 27, 2009 Report Share Posted April 27, 2009 The ratio I got from som3one that got it from his doctor, so i si nto written easy to find anywhere. But I an tell you this from the labs I have seen here it is pretty accurate and T3 onyl is the best way to treat it. -- Artistic Grooming- Hurricane WV http://www.stopthethyroidmadness.com/ http://health.groups.yahoo.com/group/NaturalThyroidHormonesADRENALS/ http://health.groups.yahoo.com/group/RT3_T3/ http://groups.yahoo.com/group/HypoPets/ Quote Link to comment Share on other sites More sharing options...

Guest guest Posted April 27, 2009 Report Share Posted April 27, 2009 Val, At this time I do not take any iodine. Since I was a child I was always told not to. I had Grave's disease as a kid and had RAI at 16 and again at 25. I was on T4 only until 2 yrs ago and only it the last 3 months have I been upping the dosage to the correct therapeutic levels. When I think of the 24 wasted years of being treated by TSH it makes me sick. Anyway, would taking iodine help me break down the T4 better so that it will not turn into RT3?
