Description
Why Choose the Holo Transcobalamin Test?
• Early Detection: Detects B12 deficiency before total serum B12 levels drop
• More Accurate: Measures only the bioavailable (active) portion of Vitamin B12
• Better Diagnostic Clarity: Especially helpful when total B12 levels are borderline or inconclusive
Preparation Required:
• Fasting is not required, but follow your physician’s instructions if part of a broader health panel
• Inform your doctor about any B12 supplements or medications you’re taking
