Ferritin of 23 with fatigue and slow recovery, should I ask GP?

[Natureismedicine]

I am 45 and on HRT, so I think hormones are sorted somewhat. But I’m a fairly active person. Walk over 10000 steps, gym three times a week, a couple of short runs a week.
Anyway, I don’t seem to recover quickly and feel drained a lot of days. Also have an injury that doesn’t seem to heal despite physio etc.
For some reason yesterday I decided to have a look at my blood test results from last year and I noticed my ferritin , despite saying normal range is 23 which seems on low side to me.
I asked chat GPT who said yes low side so I started looking into this. I seem to have a lot of symptoms which could explain how I feel most days.
NICE guidelines say under 30 should be treated as iron deficiency?
is this correct? Anyone can shed some light on this?
why didn’t GP mention this as reason I went to docs was the reasons mentioned above

My lab gives a reference range of 15 and above being normal for women (30 and above for men) so technically your result may have been within normal limits. Ferritin can also be elevated due to other reasons eg inflammation so a normal ferritin does not exclude iron deficiency.

you could go back to your gp and ask for iron or transferrin saturation levels to get a clearer picture of your iron status or take a supplement

There is an argument that “normal” levels for women are suboptimal
