Why these vitamins matter
Vitamin D supports bone, muscle and immune health, while Vitamin B12 is important for nerves and blood cell formation. Deficiency symptoms can overlap with other conditions.
Common symptoms
Patients may report fatigue, weakness, body pain, tingling, numbness, low mood, hair fall or frequent cramps. Testing helps doctors decide whether deficiency is present.
Who may need testing
Testing may be advised for vegetarians, elderly patients, people with low sun exposure, chronic acidity medicine use, diabetes medicines, pregnancy, fatigue or neuropathy symptoms.
How it fits into packages
Vitamin D and B12 are included in several preventive and premium packages. Your doctor may combine them with CBC, thyroid, sugar and liver/kidney tests for a broader review.
Frequently asked questions
These tests often do not require fasting, but fasting may be needed if they are part of a larger package.
Do not start or change supplements without medical advice, especially if you have other health conditions or take regular medicines.
