Why test for low mood?
While low mood and depression have complex causes, several treatable medical conditions can contribute. Thyroid dysfunction, vitamin D deficiency, iron deficiency anaemia, and hormonal imbalances are all known to affect mood, energy, and cognitive function. Blood testing can identify these physical contributors alongside other care.
