Above range MCV and MCH

[Digger031145]

Hi

I always get results saying my MCV and MCH are both above range. I’ve read it can be due to hypothyroid

Anyone know if ft3 plays a part in this ?

Raised MCV generally means that the red blood cells are larger than normal (macrocytic). Causes of macrocytic anemia include:

Vitamin B12 deficiency

Folate deficiency

Liver disease

Alcoholism

Hypothyroidism

Some medications, eg chemo drugs

MCH parallels MCV.

3 months ago you posted these results in this thread and had great advice from Humanbean:

Folate is 4(3.5-20.5)

B12 is 400(150-883)

So looking at those I'd be thinking it's more to do with that than anything to do with FT3. But what are your current thyroid test results?

[Digger031145 in reply to SeasideSusie]

Blood results from June 125mcgs Levo plus 15mcgs T3

Last dose 8.25 previous day

TSH <0.03 (0.35-4.94)!

Ft4 15.5 (9-19) 69%

Ft3 3.9 (2.6-5.74)41.4%

Add 20% 4.68 66.24%

In that case I wouldn't think your FT3 is causing any problems. The adding 20% is a bit of a guesstimate really, much better to get an accurate result by splitting dose the day before the test and taking last portion of dose 8-12 hours before blood draw.

If I took T3 12 hrs before blood test it would be 8pmIf it was 8 hrs before blood test it would be midnight.

I can’t take it after 4 pm as it keeps me awake

Are you taking vitamin B complex and B12 to improve low levels?
