New blood results

[les121]

So I've been taking 100mcg levo and my own Tiromel 25 daily since ...September last year...TSH...0.05...(0.3-5.5)

T3...8.5...(3.1-6.8)

T4...14.3 (12.0-22)

Ferritin...75...(15-150)

Could someone translate please

No other tests done.

When was your last dose of Levo & T3 prior to this test?

Depending on your reply to that question your FT4 is at 53% of range and FT3 over range.

What are you supplementing with?

When were your last tests for vitamins?

How do you feel?

Do you always get the same brand of Levo?

Recommended that all thyroid blood tests early morning, ideally just before 9am, only drink water between waking and test and last dose levothyroxine 24 hours before test

This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)

On T3 - day before test split T3 as 2 or 3 smaller doses spread through the day with last dose 8-12 hours before test

Do you always get same brand levothyroxine at each prescription

Do you normally split T3 as 2 or 3 doses per day

ESSENTIAL to test vitamin D, folate, ferritin and B12

Exactly what vitamin supplements are you taking

Did you stop any supplements that contain biotin 5-7 days before test

when was this test done……and what time of day

[les121 in reply to SlowDragon]

I had my medication that morning and the blood test was done at 5.40pm as it was a cancellation..

No other tests done we know what GPS tests are like ...

I take my t3 in one go also as il probably forget 😅 so this is easiest no supplements...

So you need to retest yourself including vitamins

TSH would have been higher at 9am

Ft4 is falsely high as levothyroxine was not 24 hours before test

Ft3 falsely high as you didn’t split T3 day before testing

Even if you don’t normally split your T3, always split day before testing

You quite likely have room to increase levothyroxine dose and quite likely don’t need to reduce T3

Get retest and come back with new post once you get results

And if not taking any vitamin supplements, quite likely low vitamin levels will need improving

Looks like you are over doing the T3 by quite a bit, I'd drop down to 20mcg or even 15mcg depending on how you are feeling and retest in 6 weeks, a little less T3 might help bring your fT4 up

[SlowDragon Administrator in reply to TiggerMe]

She took whole 25mcg tablet that morning

Though I agree ….might possibly need to reduce by 1/4 of a tablet….but I would retest first

[TiggerMe in reply to SlowDragon]

So that's somewhere between 8 and 12 hours prior to testing?

[SlowDragon Administrator in reply to TiggerMe]

Yes but was whole daily dose….she should have split as 3 doses and only taken last 1/4 of tablet 8-12 hours before test

[TiggerMe in reply to SlowDragon]

Ideally, but this result shows that she is over doing it as this is way too high given it would have peaked several hours before no?

[SlowDragon Administrator in reply to TiggerMe]

I would expect yes ….but I would order test now and retest correctly first

[SlowDragon Administrator in reply to TiggerMe]

actually most people who take T3 as single dose probably have this peak of over range Ft3

That’s why it’s generally better to split dose and exactly why it’s ESSENTIAL to split dose day before test

[TiggerMe in reply to SlowDragon]

Interesting, I do a single dose and have in the past tested 3-4 hours and 12 hours after to see the effect and it would peak at 1.5 higher (though not above 7.5) for the earlier test whereas the later test would be on a par with a split dose result around 6

Blood test timings

Post from yesterday showing the difference when testing correctly

healthunlocked.com/thyroidu...

FT4: 17.9 pmol/l (Range 10.8 - 25.5)

Ft4 only 48.30% through range

March test when left correct timing

Suggests you have room for dose increase in levothyroxine

Aug test when testing unexpectedly

FT4: 22.3 pmol/l (Range 10.8 - 25.5)

Ft4 at 78.23% through range
