Pregnant - do these blood tests mean anaemia?

Hi all

I’m nearly 17 weeks pregnant and I’ve had some blood tests from GP recently including the following:

Red blood cell (RBC) 3.78 - just* *under normal threshold

Haematocrit 0.348 L/L - also under normal threshold

Mean corpusc. Hb. conc. (MCHC) - 358 g/L which is at the very top of normal, 2 off being too high (also linked to types of anaemia)

Serum ferritin 75 which I think is ok?

These levels were all middle of normal pre-pregnancy. I have been taking pregnancy supplement which includes iron (which I didn’t before pregnancy).

The GP/clinician’s written comment against the results is “Abnormal - no action as not significant”

Anyone any good at reading these results or has had similar during pregnancy? I’m not sure if it’s normal or I should be supplementing iron more now so it doesn’t keep dropping and then become a problem. My vitamin D is also nearly below normal, and was really good pre-pregnancy.

I’ll contact GP but prepared for them to brush it off to be honest. I’ve already had problems with my thyroid and want to be as careful as possible.

Thanks!

Your blood volume increases when you’re pregnant which changes the blood results so a small variation from normal is expect. To show anaemia you would need your Hb value.
