Purpose of the test
The primary objective of testing for Total B12 and Active B12 is to determine the levels of vitamin B12 present in the body. Total B12 measures both the active and inactive forms of the vitamin, while Active B12 specifically measures the form that the body can use.
Who Should Get Tested
Individuals who exhibit symptoms associated with a vitamin B12 deficiency, such as fatigue, anemia, neurological features, or sore tongue, should consider getting tested. Additionally, those concerned about thyroid disorders or experiencing unexplained fatigue might benefit from this test.
Blood Test Preparation Guidelines
Time of day
It is recommended to schedule your appointment for blood tests in the morning hours between 7:00-10:00.
Fasting
It is recommended to fast for approximately 12 hours before blood sampling. The last meal of the previous day should ideally be consumed around 6:00 p.m. On the day before the test, avoid heavy and fatty meals as well as alcohol.
Stay hydrated
Drinking water prior to testing can help with sample collection.
Other factors
Tests should not be performed after a sleepless night or intense physical activity. It is recommended to avoid exercise and stress immediately before blood collection and to not smoke. A short rest is recommended.
Medications and supplements:
Blood samples should be collected before the morning dose. Some drugs can interfere with test results. Consult with your doctor whether you can delay your dose because of lab tests.
Biotin supplements:
High doses of biotin supplements can affect test results, causing false elevation or reduction. It's recommended to avoid taking biotin for at least 72 hours before blood collection. If you are taking biotin, inform the personnel collecting the blood so that they can provide specific instructions.
Interpreting Test Results
Total B12 measures both active and inactive forms of the vitamin. However, only Active B12 is available for use by the body's cells. Typically, Active B12 makes up 10% - 30% of all the B12 in the body. A test that only measures Total B12 might show normal levels, but the individual could still have low levels of Active B12. Thus, testing specifically for Active B12 provides a more accurate picture of the body's B12 status. Symptoms of vitamin B12 deficiency can range from fatigue and anemia to neurological issues and bone marrow suppression. If levels are found to be deficient, dietary adjustments or supplements might be recommended.
