Can someone help me with results of a Thyroid Peroxidase Antibodies test result?

[depauwbd]

I received my test results on my Thyroid Peroxidase Antibodies test and it was 810.4.  I have been leaving messages for my Endocrinologist and he has not returned my calls.  I only saw him once so I don't think he is that responsive  I went to see him for insomnia, weight gain, always being cold, depression, difficulty swallowing, mood swings, etc.  I cannot find any information on what a normal range is for this test.  Does any know?  Or can anyone tell me where to find this information?

I copied your results from the other thread just to make it easier for eeryone:

                          Normal           Abnormal
K Serum             4.5
CL                                              110
CO2                   25
Glucose             85
BUN                   13
Est. GFR             62
Creat.                 1.0
T3 Uptake           35.0
TSH                    1.78
TSI                       97
T3 Total Serum   88
T4, Free            0.94
Thy,Peroxid, AB                        810.4

When you post labs, you have to post reference ranges as well since those vary lab to lab and have to come from your own lab report.  The best way to do that is usually to list test, result and range in parentheses, e.g.:

TSH 1.78 (0.3-3.0)

As far as your TPOab is concerned, you can see that reference range is 0.0 to 9.0, and your result is 810.4, clearly way above range.  However, antibody counts are basically either positive or negative, and raw numbers don't mean a lot, i.e. someone with an antibody count of 100 can feel worse than someone with a count of 800.  We often see antibody counts in the hundreds or even thousands.  Just to give you some perspective, my TPOab on diagnosis was 900+, and my TGab was 3,000+.  

If you post your other ranges, we can comment further.

The lab results list 0.0-9.0 IU as normal and show my results as abnormal. However, it does not say HOW abnormal 810.4 acutally is.  So I guess I need to sit and wait for the doctor to call and let me know.

I just accidentally posted my test results on someone else's question...oops!  Not used to this site....Look at the question by Mrstarz and you can see my test results.  My physician just called me and said he never rec'd my results....right...In any case, when I told him what the results were and asked him what it meant, he just blew it off and said he was going to have to see the results from the lab first.  Which, I guess is probably appropriate.

TPO antibodies are measured in either IU (international units) or U (units). I've had my TPO antibodies measured in both IU and U.  My lab work lists normal range is <6IU or <60U.

He did another test that came back as abnormal but it is difficult for me to understand exactly which test it is.  I can just see that the results were 110.  It looks like it is my "CL" which I believe is my chloride???

Ranges vary lab to lab on TPOab, but we often see the normal range on it as "less than 20" or "less than 40".

810.4 is clearly a positive on TPOab.  It indicates that you have autoimmune thyroid disease, probably Hashimoto's thyroiditis (hypo, except in early stages.  However, TPOab is sometimes elevated with Graves' (hyper) as well.  

Did your doctor test any other thyroid functions?  FREE T3, FREE T4 or TSH?

Hashi's is one of the most prevalent causes of hypo in the developed world, so you have lots of company...I was diagnosed a few years ago.
