What is ACTIVE VITAMIN B12 (HOLOTRANSCOBALMIN)?

This test measures the active form of Vitamin B12, called holotranscobalamin, which is the only portion of B12 that cells can readily use. It provides a more accurate assessment of your body's B12 status compared to total B12, helping to detect early deficiencies.

Why is this test important?

Active B12 deficiency can lead to various health issues, including anemia, nerve damage, and cognitive problems. This test is crucial for diagnosing B12 deficiency, especially in individuals with symptoms or those at risk, such as vegetarians, vegans, and people with malabsorption issues.

How to Prepare

Fasting for 8-12 hours before the test is generally recommended. Please confirm specific instructions with your healthcare provider.
