B12

Vitamin B12 supports red blood cell production, neurological health, and DNA synthesis. The Vitamin B12 test (Total) measures all circulating forms of B12 in the blood. Deficiency may lead to anaemia, nerve damage, mood changes, and cognitive decline if not detected early.

Why Vitamin B12 Total Test Matters?

This test provides a general overview of B12 levels, helping identify deficiencies caused by poor diet, absorption issues, or medical conditions. Detecting low levels helps guide treatment and prevent long-term complications.
