The different lab test methods and new results (edited post)

[Guest guest]

Hi Fragrance

Sensitive TSH 6.100 mIU/l (0.270-4.200) This is still too high. It needs to be around 1.0 for you to feel better.

FT4 16.680 pmol/L(12.000-22.000). This is also too low. FT4 when being treated should be in the upper third of the reference range.

FT3 4.630 pmol/L (3.100-6.800) This is also low. This should be above the half way line at least for you to feel good. You are not taking enough L-thyroxine.

TPOAB >600 Iu/mL (0.00-34.00)---why don't specify the level? You have Hashimoto's. This is a cause of hypothyroidism.

TGAB 30.05 % (0.00-30.00) tested by RIA in another machine

Following are my previous lab results, which do you think they are less precise/accurate for their testing method? I don't know what method they are using.

FT3 4.42 pmol/L (2.5-6.5)

FT4 17.48 pmol/L (11.5-23.2)

TSH 6.02 mIU/l (0.35-5.5)

rT3 0.12 ng/mL (0.2-0.64)

TPOAB before treatment 1000.00 IU/ml (0-35)

So do you think I should go to the newly visited hospital to have better tests? Does the .000 other than .00 matter much? However, their results for TPOAB seems not accurate, just >600?

Not sure Fragrance, both these results show you to be hypothyroid. I know nothing of the different forms of testing. Somebody else may be able to help you with this.

Thanks

----Sorry, Sheila, I forgot to attach the results of antibodis, so post another one. please delete the first one. thanks.

" Third generation " really refers to the precision and limits of sensitivity, not

to the technology involved. For most tests, it only makes a big difference at

the end of the scale, TSH less than 0.1, for example. That used to be all they

could measure. High precision really only makes sense for research.

That means your antibodies saturated the limits of the assay. It does not make

much difference to say HASHIMOTO'S! rather than just Hashimoto's.

If you have to travel a great deal or pay more for the extra precision, it is

not worth it.

Thanks. Sheila and Chuck

Yes, I have to increase my dose ASAP cuz I feel very hypo as if I went back to the pretreatment condition. For that, I am considering that it could be possible I need another 50 mcg to fill in the defficiency gap.

It is almost the same payment that I have the two forms of tests. but I think it is better for me to follow up my results in the same lab, which could be easy to compare with one another for dose increments even though I could calculate for % of TSH and FTs. And I noticed that the lab span/range for "normal" TSH is narrower than the other. (0.270-4.200) vs (0.35-5.5). Since the unit they use is the same, that means it is more reasonable in elevating one's thyroid's health?

It depends on how they define the reference range. Usually it is the one-sigma

range for a random group of untreated asymptomatic people. However, one or both

ends may be adjusted to accommodate concerns about safety during treatment.
