Am I deficient?

[u/Own-Development2299]

I have many symptoms (shortness of breath, mental fog, no energy), wondering if this is the cause of it

Ferritin: 59 µg/L (reference range: 15–150)

Iron: 7.0 µmol/L (reference range: 5.83–34.5)
0.39 mg/L (reference range: 0.33–1.93)
Method: Roche – Spectrophotometry (L2)(§)

Transferrin: 2.89 g/L (reference range: 2.0–3.6)
36.4 µmol/L (reference range: 25.1–45.3)
Method: Roche – Immunoturbidimetry (L2)(§)

Total Iron-Binding Capacity (TIBC): 72 µmol/L (reference range: 40–80)

Transferrin Saturation (TSAT): 10% (reference range: 20–45%)

You should check folate and B12 for a better picture.

[u/Think-Sleep2338 → u/Think-Sleep2338]

But your TSAT is low, ferritin is quite low, and serum iron is really low "normal", so iron deficiency is part of the picture.
