Cost, profitability and value of laboratory diagnostics: in God we trust, all others bring data

AbstractAlthough laboratory tests are the most used diagnostic investigations for screening, diagnosing, prognosticating and therapeutic monitoring of most human diseases, laboratory medicine is currently seen as many other economic industries by some policymakers and administrators, and is hence subjected to scale economy and assessed accordingly, despite the incremental clinical value that laboratory tests can generate. According to a genuine economic perspective, the impact of diagnostic testing on a healthcare budget is lower than 2.5%, whilst its profitability is over 100%, a net profit margin over 7-fold larger than whatever other human industry. Even more importantly, the impact of laboratory tests on clinical outcomes is now clear and virtually incontestable, as their use will improve clinical pathways much more than any other diagnostic investigations. The many ongoing attempts to downsize the importance of laboratory medicine as costs centers, or even the concept that public laboratory services can be safely eliminated or outsourced to external private professional organizations, shall hence be challenged. Laboratory medicine not only is vital to patient care and patient flow, and will remain so for many years to come, but is also a valuable economical resource for the healthcare facilities
