Clinical Approach

Why We Often Recommend Blood Testing Before Treatment

While some patients attend for ongoing prescribed Vitamin B12 injections, others may be experiencing symptoms such as tiredness, fatigue, or reduced energy without knowing the underlying cause.

Because these symptoms can also be associated with iron deficiency, thyroid disorders, Vitamin D deficiency, folate deficiency, or other medical conditions, we may recommend appropriate blood testing before treatment where clinically suitable.

Our aim is to help identify the underlying cause rather than simply treating symptoms.
