Re: first post with lab results

[Guest guest]

Honestly I am not used to reading Doctor's Data results but it looks like you are 76% saturated. Without a bromide level it is hard to tell if this is a true number or not. You may be lower if your symporters are blocked by bromide. If that is the real number you are low - target is 90%.

first post with lab results

Hello, I am new here and am happy I found this helpful site.I've been learning a lot from the group and thought I'd post my first question.I had some iodine tests done in the past so I thought I'd see what you guys thought about the results. I have hypothyroidism and am a member of the NaturalThyroidHormones group. My symptoms continue even though I take all suggested supplements and am up to 3 grains of ERFA.One thing I don't do is take Iodine. So I thought I would start looking into this. I just ordered some Iodoral and Dr. Browstein's book today.Here are the two tests I've had that I was wondering about. Do they say I am low in Iodine? Doctor's Data 24-Hour Urine Iodine (Loading Test) 08/24/2009Iodine 38 (ref 0.1 - 0.45 mg/24 hr)% Excretion/24 hr 76%(I noticed that my result of 38 is way outside the reference range. No, I didn't miss a decimal point.)Creatinine 1330 (ref 600 - 1900 mg/24hr)Quest Diagnostics 09/16/2010Iodine, random urine 91 (ref 34 - 523 mcg/L)Thank you! G. in Philly

Something here sounds wrong.

If the Iodine excreted during the 25 hour loading test is 38 mg, and the loading

dose is 50 mg, then Doctor's Data report of 76% excretion seems correct.

But the reference range doesn't. Based on a 50 mg loading dose, that range

corresponds to an excretion rate of 0.2% to 0.9%. That does not make sense.

Normally, the reference for this test is 10% excretion (90% saturation). I don't

think I've ever heard anyone claim that people on iodine should aim for greater

than 99% saturation! Maybe Superman could do that, but not the rest of us.

It's hard to be sure, but I'd guess that while you are indeed iodine deficient

based on this test, with an excretion of 76% instead of the desired 90%, it's

not nearly as dire as that reference range would suggest. But perhaps I'm

missing something.

Your doc could call Doctor's Data for a clarification of these results, and in

particular that strange reference range.

Thanks a lot for your responses. I will give Doctor's Data a call. I too thought

that reference range seemed incorrect - or something.

Are urine sample tests worth looking at? Mine was:

Iodine, random urine 91 (ref 34 - 523 mcg/L)

Thanks!

The iodine reference range is based off a baseline iodine test. This is the test

that you do before taking the 50mg of iodine. This is done to make sure that

there is no supplemental iodine taken before the loading test (this would

increase your % excreted).

0.1-0.45mg/24hr is 100-450ug/24hr. This is what you typically see in a

non-supplementing iodine " sufficient " individual.

My guess is that they used the wrong reference range because it says (loading

test). They also doubled the mg amount to show % excretion.

To the person who posted a random urine iodine spot test result. Your iodine

level is a bit lower than normal for a non-supplementing individual (Based on

WHO numbers). This level can vary based off of what you eat, when you eat, urine

dilution and the diurnal iodine variation. It would also be helpful to know

what time of day you took the test. The test ZRT offers looks at two spot tests

done at specific times to determine a baseline iodine level in the

non-supplementing individual.

Ted, thanks so much for message. It's quite helpful. I'll give them a call to

see what happened...And thanks for the info on the urine test as well!
