Emergency diagnosis Treatment/monitoring Clinics Doctors’ office testing (POL) Self or home testing Bed side Operating theatres Applications of POCT
9
Faster TAT Small sample size Reduced pre-examination errors Eliminate or minimize preparation steps Improved patient satisfaction Faster decision making and follow-up with patient Better management of therapy Convenience Advantages of POCT
