Antibiotic Resistance and Diagnostic Tests: What You Need to Know

What Is Antibiotic Resistance? 

Antibiotics are drugs used to treat infectious diseases. However, these drugs have been overused in people and animals for so long that they are becoming less effective. Antibiotic resistance means that an antibiotic is no longer effective against a certain type of bacteria. When this happens, doctors have to try other antibiotics to treat an infection. Unfortunately, antibiotic resistance is only getting worse. As a result, medical and public health professionals across the world are calling for an end to misuse and overuse of these drugs so antibiotics will continue to work when they are needed. 

Why Should You Care?

Antibiotic resistance has led to a rapid increase in drug-resistant infections and is changing the practice of modern medicine. If current trends continue, doctors will be unable to treat common ailments such as urinary tract infections. Without effective antibiotics for prevention and treatment of infections, the success of organ transplantation, cancer chemotherapy and major surgery will be compromised. Antibiotic-resistant bacteria could turn even a simple cut or scrape into a life-threatening or deadly infection. 

How Can We Fight Antibiotic Resistance?

There are several ways to fight antibiotic resistance including: changing the way antibiotics are used; reducing unnecessary uses of antibiotics in people and animals; and improving infection control efforts. Another important tool to help in the battle against antibiotic resistance are diagnostic tests that can identify the cause of an infection and, in turn, help improve prescribing decisions. 

What Is a Diagnostic Test?

A diagnostic test is a medical procedure that can help healthcare professionals determine what infections require treatment with an antibiotic and those that do not. Diagnostic tests hold the potential to differentiate viral from bacterial infections as well as predict which antibiotic will be most effective. These tests also can help determine when antibiotics are no longer needed. Diagnostic tests continue to evolve and are providing more information in a shorter period of time, thereby allowing better decision-making by healthcare providers to improve patient care and combat antibiotic-resistant bacteria. There are many innovative, safe and effective diagnostic tests available to doctors and clinicians today. 

What You Can Do

➔    Ask your healthcare provider if a diagnostic test is available to determine whether you need an antibiotic or not.
➔    Never demand an antibiotic from your healthcare provider.
➔    Only take an antibiotic when you need it and finish the full course as directed by your doctor and pharmacist.
    Learn about antibiotic resistance and urge your friends and family to use antibiotics only when absolutely necessary.
➔    Urge Congress to support investments in the development of new diagnostic tests.
