It's interesting that in this heart study, they consider
absolute iron deficiency when ferritine is below 100 ng/ml (= 100 µg/l ) and
relative iron deficiency when ferritine is between 100 and 300 if Transferrine Saturation is below 20%
(just to compare, here what french lab gives as reference ranges!!!)

...
Of the 1.12 million adults seen regularly, 20 219 were classified as having definite or probable HF
....
The most common comorbidities in people with HF were
-hypertension (41.1%),
-chronic obstructive pulmonary disease/asthma (25.1%) and
-depression/anxiety (18.4%). ...
Just over one-third (37.8%) had iron deficiency
....
While anaemia was infrequent, absolute iron deficiency (defined as serum ferritin level of <100 g/L) was surprisingly common.
Haemoglobin levels were available for 17 382 participants in the definite and probable HF populations.
Of these, 611 (3.52%) had a documented haemoglobin level of <100 g/L.
Ferritin levels were available for 13 604 patients with HF, and 6479 patients (32.0%) recorded a ferritin level of <100 ng/mL.
Relative iron deficiency affected a further 7.6%, with 5205 (25.7%) recording a ferritin level in the range 100–300 ng/mL and just under a third of these (1546) also having a transferrin saturation of <20%.1
Therefore, over a third (39.7%) of the 20 219 patients with HF had documented evidence of absolute or relative iron deficiency.
