Hello Doctors,
I am posting this query on behalf of my 20-year-old sister. Her recent blood tests show low haemoglobin (9.3 g/dL), low iron (30 µg/dL), low transferrin saturation (7%),
Vitamin D (12.1 ng/mL) and
Vitamin B12 (191 pg/mL).
We would like your advice on what could be causing these deficiencies, whether any further tests (such as serum
ferritin) are required, and what treatment or supplements you would recommend.
Thank you.
