Diagnostic Procedures You Can Expect in the ER


When you visit the ER, diagnosing your condition is the first action the doctors will take. A number of different diagnostic tests can be performed in the ER so that doctors can provide you with the urgent care you need. The right tests for you depend on your symptoms and medical history, but here is a look at some of the tests the ER physicians may order:

Blood Tests

Blood tests can help your doctor diagnose a wide range of conditions. Blood tests can help your doctor determine if you’re suffering from a heart attack, have high or low blood glucose levels, have a problem with your liver, or any number of other health problems. Blood tests are also useful in cases of drug overdoses. In some cases, blood tests may be the only diagnostic exams your doctor needs to perform, while in other instances, they are used in conjunction with other tests.

Diagnostic Imaging

Diagnostic imaging tests, like X-rays and CT scans, are also important components of care in the ER. Imaging tests can diagnose broken bones, inflamed organs, torn muscles, and more. They can also be used to help determine if you are having a stroke. Diagnostic imaging may be used for diagnosis and also to track the effectiveness of your treatment after you’re discharged from the ER.


An electrocardiogram, or EKG, tracks the electrical activity of your heart. An EKG is an important part of diagnosing heart attacks. If you go to the ER with chest pain, then an EKG will almost certainly be part of your care.
