What does high mean cell haemoglobin with low red blood cell distribution mean?

[Chui]

Hi. Post Covid I've had several issues which may overlap with or add to my ME, or be just (!) Covid. My doc has done a whole raft of tests. Most are within range albeit at one end or the other. Except for these. Its minimal so perhaps they will ignore them, but any ideas as to what it could mean please?

Mean cell haemoglobin level 32.1 pg [27.0 - 32.0]

Above high reference limit

Mean cell haemoglobin concentration 340 g/L [315.0 - 345.0]

Red blood cell distribution width 11.1 %CV [11.6 - 14.0]

Below low reference limit
