There is a great increase in the need for better health care in recent years. The point of care technology (POCT) devices has become an essential part of health care due to its convenience and speed. A growing problem in the world is the increasing number of obese people in the world. A way of determining whether a person is obese is by determining the adiponectin level in their body. The work will show experimental proof of this determination theory. This work also presents a system that will make use of magnetic particle assay (MPA) as a means of implementing this diagnosis. The work also includes a discussion on the sensor that is used to quantify the number magnetic particles after performing MPA on the sample as well as a prototype developed as a proof of concept for this work.
