A New Cost Effective And Less Cumbersome Method To Detect Levels Of A Vital Vitamin


There is some good news for the patients who are victims of the vital vitamin B12 deficiency. According to recent reports from Press Trust of India (PTI) researchers of University of Adelaide have found a breakthrough approach to detect the vitamin B12 deficiency in humans. They have developed a first of its kind optical sensor which has the capacity to quickly detect any vitamin B12 deficiency in humans. Vitamin deficiency can increase the risk of dementia and Alzheimer’s disease in humans.


This first of its kind device helps tracking levels of vitamin B12 in high-risk patients and also plays a role in early intervention by giving the patients sufficient doses to cover the shortfall. This new method also takes care of the current limitations in testing methods which are considered cumbersome and costly.

According to Georgios Tsiminis, who is a research fellow at the University of Adelaide in Australia, the deficiency of vitamin B12 can lead to a “potential modifiable risk factor” for diseases like dementia and Alzheimer’s. The deficiency of this vitamin in the body according to him leads to cognitive decline.
Mr Tsiminis added that older adults are a higher risk of vitamin B12 deficiency. This is due to age-related reduction which happens because of the decreasing capability of the body to absorb the vitamin B12 received through their diet.

According to Mr Tsiminis,  the sensor which has been developed by the team of researchers from his University is the first step towards “a point-of-care solution” for the purpose of measuring and “tracking B12 in healthy ageing adults”. Mr Tsiminis added that this new method will empower the doctors to tracks the levels of this vital vitamin in the body and give adequate dose when required to overcome the shortfall.

Currently this optical sensor is only at the proof-of-concept stage. But when developed it can have wide-reaching potential applications.

Mr Tsiminis has made it clear that the optical device currently helps in diagnosing deficiency in vitamin B12 in a general practice setting. The research fellow however asserted the fact that this is first time in history that a quick technique is developed the on the basis optical spectroscopy which is able to detect vitamin B12 in human blood serum. Mr Tsiminis feels that it is a first “promising step” on the way towards achieving their goal.

This optical sensor takes less than a minute to measure the amount of vitamin B12 in human blood and it also requires minimum preparation. Using this new method researchers have shown for the first time that vitamin B12 levels in human blood serum can be measured without the help of traditional lab techniques.
