Many people who have their blood tested may come across elevated levels of vitamin B12. While vitamin B12 is essential for our health, excessively high levels of B12 in the blood, may indicate an underlying health issue. In such cases, it is important to investigate the underlying cause of the elevated B12 levels. One test that can be used for this purpose is the B12 binding capacity test. In this article, we will discuss the role of the B12 binding capacity test in understanding elevated B12 levels.
When we consume vitamin B12, it is absorbed into the blood stream and eventually it is bound to a protein called transcobalamin. This vitamin B12-transcobalamin complex is then transported to and into our cells. It is here inside the cells where vitamin B12 is used for its various functions.
B12 Binding Capacity Test
The B12 binding capacity test measures the amount of transcobalamin molecules in the blood sample.
If a person has a lot of transcobalamin in their blood, they are likely to have a lot of binding capacity. Transcobalamin is one of the binding proteins for B12 and helps transport the b12 throughout the blood. If a person has a lot of binding capacity, it means that there are lot of available places for B12 to bind to.
Deeper Understating of Your Elevated B12 Levels
People can have high B12 for many different reasons. The advantage of this test is it helps narrow down what some of those reasons could be. In the case of elevated B12 levels, a high B12 binding capacity, indicates that a lot of transcobalamin molecules are floating around in the blood. In this case too even though the b12 level is high there are still plenty of binding place available. In this scenario we would conclude that this person's body has a surplus of transcobalamin. This can happen in certain health conditions and scenarios.
On the other hand, if a person has elevated B12 levels but a low B12 binding capacity, it indicates all the transcobalamin has b12 on it. This person is likely consuming too much B12 through their diet or supplements. Alternatively they are not making enough transcobalamin binding proteins.
Using transcobalamin Binding Capacity test
It is important to note that the B12 binding capacity test is not typically a standalone test or diagnostic tool. It should be used to provide additional information and context to the results of other tests and symptoms you might be experiencing.
We would typically use it for people that have persistently elevated B12 levels and experience other ongoing health symptoms. This will help us understand if the elevated B12 level is coming from too much intake of B12 or from some deeper health issue.
So elevated B12 levels can be an indication of an underlying health issue, and it is important to investigate the cause of the elevation. The B12 binding capacity test can provide additional information to help understand the elevated B12 levels, but it should not be used as a standalone diagnostic tool.
