Ferritin is a marker of iron stored in the body. Fatigue is a classical symptom of iron deficiency anaemia - which is due to a decrease in iron levels.

This patient is most likely suffering from a thyroid induced issue, however, even if ferritin is measured, you would expect it to be **below** the normal ranges, not above.

T3 is similar to thyroxine (T4) - it is the precursor to T4. This patient is most likely presenting with hypothyroidism - a decrease in the thyroxine (T4) levels in the body, Since T3 is the precursor to T4, this means that we would also expect to find a **decreased** level of T3 in the body.

c
Triiodothyronine (T3)
QuestionChoice
This patient is presenting with classical symptoms of hypothyroidism. This is a decrease in the levels of thyroxine in her body.

If this is due to the woman's thyroid not producing enough T4, there would be an **increase** in thyroid stimulating hormone (TSH) since this patient's pituitary gland will be trying to compensate for the decrease in T4 levels. This patient's thyroid gland however is not reacting to the increased TSH levels.

Thyroid-stimulating hormone (TSH)
QuestionChoice
Transferrin is a protein produced by the liver that binds to iron. The more iron bound to transferrin, the less transferrin there is available in the body.

Transferrin is a good indicator for iron deficiency anaemia, where you would expect to find an increased level of it.

However, this patient is more likely to suffer from hypothyroidism than iron-deficiency anaemia (IDA). Despite her fatigue, which is a symptom in both hypothyroidism and IDA, her hair loss, weight gain, low mood and cold intolerance are much more indicative of hypothyroidism. TSH levels are more likely to be raised than transferrin in this patient.

Transferrin
QuestionChoice
This woman is presenting with classical symptoms of hypothyroidism. Hypothyroidism indicates a decrease in the levels of thyroxine in the body (hypo- means below in Latin).

You would therefore expect to find a **decreased** level of thyroxine in this patient.

A 38 year old female presents to General Practice with a 5 month history of fatigue, weight gain and hair loss. She also complains that she often feels cold on a hot summer day.
