Active-B12, Holotranscobalamin (holoTC)

What it measures

Vitamins

Clinical significance

Holotranscobalamin represents only 10-30% of the Vitamin B12 circulating in the blood but is the ONLY form of Vitamin B12 that is taken up and used by cells of the body, hence it's other name ACTIVE -B12. An active B12 test measures the amount of B12 that available for your body to use. Vitamin B12 is important for red blood cell formation and a healthy nervous system. B12 deficiency can cause almost any psychiatric symptom, from anxiety, and panic to depression and hallucinations. This is because B12 deficiencies trigger symptoms in the nervous system and red blood cells.

The normal range for holoTC is 23–100 pmol/L. Low holoTC is an early indicator of low B-12.

Emerging evidence indicates that a low level of Active B12 is a more reliable marker of impaired vitamin B12 status than a low level of serum vitamin B12. Moreover unlike serum B12, Active B12 is believed to be stable in pregnancy.

My journey back to health with Healsens. Thank you!!

That's when I turned to a nutritionist and ordered a blood test through Healsens. … Four months later, I retested. My biological age dropped to 24—nearly a decade younger than my real age.

Useful app to track analytics and 2nd opinion

It helps me track main parameters, understanding what do they mean and correlations, and make critical analysis to make preventative changes. Hope too see new fichas soon!

Everything is great! Excellent app! It's very convenient for storing all your test results! The only thing I wish was that you could record blood pressure readings for both arms, as this is sometimes important for blood pressure monitoring.

A useful app. It motivates me to lead a healthy lifestyle and monitor my diet. After the test results, I decided to change my diet – I cut out flour and chocolate. I lost 2 kg in about a week. We'll see how the test results look over time.
