Vitamin B12 is crucial for the formation of healthy red blood cells and plays a key role in maintaining a healthy nervous system. Deficiency can lead to issues like anemia and nerve damage.
On the other hand, low levels of Vitamin D3 can lead to reduced bone density, increasing the risk of fractures and conditions like osteoporosis. Adequate Vitamin D3 levels are vital for bone health and overall well-being.
Vitamin D deficiency is common and may affect bone strength, mood, and immunity. Testing helps your doctor decide if supplementation is needed.
Fasting is typically not required for a vitamin D blood test unless bundled with fasting panels.
Reports are usually available within 24–48 hours via secure digital delivery.
