A few weeks ago my GP finally sent me for more blood tests after I complained about my ferritin repeatedly dropping and I took private blood results to show her it was low in range. I'd mentioned it a month before and they didn't want to check because it was all 'normal' before.
After seeing the adults she decided to recheck ferritin and after I asked why it kept going low she said probably because of periods, but decided to add a coeliac screen.
I managed to get a printout of my results but I'm not really sure what they are telling me, if anything.
TTG (IgA) <0.1 (0-7)
Serum IgA L 0.21 (0.8-4 g/L)
Oh and ferritin had dropped to 9.5 (20-300 ug/L) so I'm now on iron tablets twice a day.
