Blood test results - what are high MCV & MCH please?

[KatyMac]

I'm getting there (I think) with understanding them - but these 2 are a bit confusing

MCV is number of blood cells & MCH is lots of haemoglobin - is that right? So how does that relate to Pernicious anaemia?

Thanks

How high are they? Sometimes you can be out of range but it is not a concern.

Only just outside I think 102 & 37. Something

But my mum has pernicious anaemia and I'm having some problems (gastro/mouth ulcers/pain/tiredness)

So we're trying to work it all out

It basically means that you have larger than normal red blood cells which can be associated with certain disorders including pernicious anaemia.

Thanks

Is it connected with auto immune or rheumatoid arthritis or anything like colitis?

Can be. Probably best discussing with your GP or gastroenterologist. Your results are only just outside the normal range though - presumably you've had your B12, folate and thyroid checked? I know you've had quite a few tests lately.

Thyroid yes, but the others are booked for tomorrow

I think the GP has been so 'used' to my previous diagnoses we are struggling to rethink iyswim

Thyroid was 3.09 & 15 so I think they are fine

Don't have a gastro yet - but I think I'm getting one

As far as I know, they are not considered when considering a dx for rheumatoid arthritis or ulcerative colitis. Given that they are only slightly outside of range, most doctors will not think much of them. A specialist is the best person to see to get proper investigations.

P.S. bit grim but do you get globules of blood in your stool? That is a key sign of colitis.

I have had (mixed with mucous?) & quite dark; more recently only when I've accidentally exposed myself to something I've excluded

The GP is looking at borderline stuff because after 20 years of IBS/CFS & several years of FM things are getting worse & while it could be a recurrence of the CFS it's possible/likely it's something else (& may have been all along)
