I recently had the thyroid hormone 24 hour urine test completed but I don't know how to interpret the results.
T3 = 1248 (pmol/24h) normal range = 592 -1850
T4 = 421 (pmol/24h) normal range = 347 - 1994
T3 : T4 Ratio = 3.0 normal range = 0.50 - 2.00
I went to my doctor with these results and he told me that my T3 and T4 were in the normal range. I said I understood that but the ratio of T3:T4 was outside the normal range. He said they don't even look at that any more and that there's nothing wrong with me, go on away home.
I couldn't find enough information online before I visited him about the ratio of T3:T4 so I couldn't argue with him over it's relevance. Can anyone explain?
