Comparing vitamin D test methods for hospital staff
This study compares three ways to collect a blood sample for vitamin D testing: a finger-prick, a device on the upper arm, and a standard blood draw from a vein. It aims to see which method gives the most accurate results and which one people prefer.

This study compares two types of vitamin D supplements – one made from fish waste and one synthetic – to see if they work equally well in healthy adults who have low but not severely low vitamin D levels. If you qualify, you would take one of the two supplements and your vitamin D levels would be monitored over time.
This trial compares a new blood test (Maglumi X3 SNIBE) for measuring vitamin D levels against standard methods. It includes healthy volunteers and patients scheduled for major surgery, to see how well the new test works.
This study tests how accurately a vitamin D blood test works with fresh versus frozen samples. Your blood samples will help researchers understand the best way to store and measure vitamin D levels.
This study compares different forms of vitamin D3 to find which works best for adults with low vitamin D levels. If you have a vitamin D deficiency and are generally healthy, this trial may help determine the most effective supplement for you.
This study compares finger-prick blood samples with traditional arm vein blood draws taken during your regular clinic visit. It aims to see if finger-prick testing is a good alternative for monitoring conditions like autoimmune diseases, transplants, or mental health disorders, especially for children.
This study checks whether people can collect their own blood sample using the Tasso+ kit and still get reliable test results. It may help make future diagnostic testing easier by supporting at-home or self-collection of samples.
