Activated Vitamin B12

Optimal Result: 37.5 - 188 pmol/L.

Activated Vitamin B12, also known as holotranscobalamin (holo-TC), is a significant biomarker for Vitamin B12 status in the body. Unlike total B12, which measures both active and inactive forms, holo-TC specifically indicates the amount of Vitamin B12 that is available for cellular uptake and use. This makes it a more precise marker for assessing B12 deficiency, especially in clinical situations where accurate diagnosis is crucial. Holo-TC is particularly useful because it correlates well with intracellular erythrocyte B12 levels, providing a clearer picture of B12 availability at the cellular level. This biomarker is crucial for diagnosing and monitoring conditions related to Vitamin B12 deficiency, such as neurological disorders and certain types of anemia. The method commonly used for measuring holo-TC is flow cytometry.

What does it mean if your Activated Vitamin B12 result is too low?

Low levels of activated Vitamin B12 (holotranscobalamin) can be indicative of a Vitamin B12 deficiency, which may lead to various health issues. This deficiency can result in conditions like anemia, neurological disorders, and cognitive disturbances. Vitamin B12 is crucial for DNA synthesis, red blood cell formation, and neurological function. Causes of low levels include dietary deficiencies (common in vegetarians or vegans), malabsorption disorders (such as pernicious anemia or gastrointestinal disorders), and certain medications. Diagnosing and treating B12 deficiency is important to prevent long-term health complications. For precise diagnosis and treatment, consulting a healthcare provider is recommended.

What does it mean if your Activated Vitamin B12 result is too high?

Elevated levels of activated Vitamin B12 (holotranscobalamin) are relatively less common compared to deficiencies, and their clinical significance can vary. Elevated holo-TC levels could be associated with certain medical conditions or factors, such as liver disease, renal dysfunction, or certain types of leukemia. However, the interpretation of elevated holo-TC levels should be done cautiously and in the context of a patient's overall health status, medical history, and other laboratory findings. It's important for healthcare professionals to evaluate these levels along with other clinical indicators to determine the underlying cause and appropriate management. For specific medical advice, it's always best to consult a healthcare provider.
