LILY IN THE TEST TUBE is a fine work of creativity that dives into exploring and painting on a canvas the beauty of the treasures in medical laboratory science. We often look at career fields as structured frameworks full of drudgery works that must be done and forget the fine lines and curves that make up these structures, and as such lose sight of the beauty that lies within the romance of human potentials and service provision to humanity in many fields of life work. This book helps every reader to have a basic understanding of the rationale behind the work of medical laboratory diagnostics, how it has evolved through time, the treasures it holds for patients, the medical laboratory scientists who perform the work, and other healthcare professionals who utilize the outputs of the laboratory. It also goes further to outline the challenges faced and suggestions on moving ahead. This book is a useful reminder to every user of healthcare services that a lot of soul and effort go into doing the work of medical laboratory service provision and we the people who benefit from these should also meet it halfway with the reciprocation of due recognition and appreciation it deserves.
