help me decifer my t3/t4 results

[niki86]

my free T4 is 0.89 which showed up at the lowest part of the normal range. could this indicate a thyroid problem even though it's still in the normal range?

also, they only tested the t3 and t4 once, but kaiser is listing 2 results for each.
for the same blood test i had yesterday, they're saying my free T4 is 1.02 a little further up on the listing it's recorded as 0.89
for the same blood test my T3 is listed as 118 and also 126

I"ve just recently had thyroid functions done...... TSH was 4.9  lab values .40-4.00...T4 was 1.7 labs..0.7-2.3  and T3 was 4.1 lab vals 0.7-2.3.   Last time I had labs done was 2 years ago and T3 was eleved by 1/10th of a number above normal....... I am very confused and need more info....... the Doc here ignored all the symptoms I am having and said nothing needs to be done at this time....

tsh is normal, t3 is 118. i think that's normal.

It indicates you may be Hypothyroid, or getting very close.

Does your Free T3 look better? Without lab ranges I can't tell. My guess is your T3 is higher than your T4.

Did they run a TSH?

thanks. does this mean that i'm hyper or hypo thyroid? or almost?

A normal Free T4 or Free T3 result should be in the upper half of the lab range, but not clear at the top.

Upper half to two thirds the way up is normal.

Bottom of normal range is too low.
