High Free T4, Low T3, and Off the Chart High B12 Level: What's Going On?

Just got lab work back and I have high Free T4 but low T3 and off the chart high b12 level (over 1500) with low MPV. Which seems to be contradictory from what I know. I’ve been trying to figure out what’s going on for a few months now but so far not much help from doctors or trying to look up what’s linked to what and what it could possibly be. I’ve had a lot of worsening/debilitating symptoms and new issues this year but honestly they’re too many to list. I’d could be fine or unconcerning but my theory is if I can figure out what’s going on I can work to fix it rather than just ignore until it’s too bad like my doctors have advised me to do. If anyone has knowledge to share that’d be greatly appreciated!

Also, being somebody who draws blood I know that if the blood was drawn incorrectly it can cause skewed results. Maybe request a redraw

can you explain how someone can draw blood incorrectly? Is it because they store it wrong after drawing or actually putting in the needle and getting the blood out could be done wrong??

thanks for the comment! I didn’t know that and will ask about a redraw to be safe if I can’t figure it out soon.

Sometimes when you have high T4 I can start converting to reverse t3 so maybe check reverse. This is what my doctor told me

thanks for the input! Do you know if you can supplement with more iodine if that’ll prevent conversion of reverse t3 or is it more complex than that?

This is confusing me, and I can tell it's confusing you as well. Low MPV and low T3 make me think hypothyroid. The high free T4 points to hyperthyroid. Did you have a TSH done as well?

Yes so confusing! Thanks for your reply! I went over recent labs to check about TSH. So I’ve had 3 different labs done within this year from different doctors/specialists and my TSH is normal range for all of them. The previous labs T4 was tested but not as FREE T4 and those came back in normal ranges. This year I’ve had lot of different labs test levels off then the next time they’re checked it’s back to normal aside from - low sodium, high albumin, low alk phosphate, and “managed” anemia, but those have been like that for years now and not too far out of normal ranges. Im trying to learn more about hormones and levels so I can get a better understanding but if you have further direction to point me in I’d appreciate that.
