Theoretically, all patients on antibiotics need a drug sensitivity test, but not all patients are tested clinically. The need for drug sensitivity testing depends on the type of antibiotic used. With the widespread use of antibiotics nowadays, the rate of drug resistance is gradually increasing, and in terms of national strategy control, patients are required to be sent for drug sensitivity testing when they encounter certain levels of antibiotics. If you do not send a drug sensitivity test, the clinical aspect is a non-compliant practice. The drug sensitivity test is because the use of antibiotics is mostly empirical, but empirical treatment causes further increase in antibiotic resistance. Accurate drug sensitivity testing, on the other hand, allows doctors to target their patients with a very precise use of an effective antibiotic to reduce the incidence of resistance. For patients, it can also reduce their financial burden and shorten the treatment cycle.
