About This Test
Vitamin B12 keeps your nerves and brain working well and helps your body make healthy red blood cells. Low levels can cause tiredness, pins-and-needles, poor balance, and memory trouble. Levels can drop with low intake, stomach issues, or some medicines. This test is commonly included in routine check-ups to detect problems early.
